Actinolite is usually found in metamorphic rocks, such as contact aureoles surrounding cooled intrusive igneous rocks. It also occurs as a product of the metamorphism of magnesium-rich limestones. Pyrite is usually found with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic rock, as well coal beds, and as a replacement mineral in fossils. Actinolite is an amphibole silicate mineral. It is named after the Greek word "aktinos" meaning “ray” in allusion to the mineral's fibrous nature. Fibrous actinolite is a type of asbestos and was once mined along Jones Creek at Gundagai, New South Wales. Pyrite or "Fool's Gold" is the most common sulfide mineral. It is named after the Greek "pyr" meaning "fire" because it can be used to create sparks needed for a fire if struck against metal or a hard surface. Due to its gold colour, pyrite can be mistaken for gold and often forms alongside it, causing small amounts of gold to be present in rocks containing pyrite. Most importantly, pyrite is an ore of gold. Pyrite is sometimes used as a gemstone but is not great for jewellery as it easily tarnishes. In some fossils of ammonites – shelled cephalopods that died ~66 million years ago – pyrite also replaces the shell. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.

Malachite is a water soluble, crystalline, triphenyl methylene chloride salt. It has a close relationship to copper because it is common for Malachite and copper to come from the same ore. Malachite often has shades of green, making it also known as Malachite Green. As a result of it's colour, it is known for being a dye and has been used in the dye industry, the textile industry and in medical fields. Cobar in New South Wales is well known for it's mining. This is because of the number of important deposits present in the area and include three important mining belts where most of the materials are found. These are the 'Cobar belt', the 'Canbelego belt' and the 'Girilambone belt'. The 'Cobar belt' runs underneath the main town. Copper was first discovered in Cobar in 1869 and since then, many deposits of other materials have been found, including Malachite.This specimen is significant because it comes from Cobar, NSW and represents the many deposits of materials found there. Cobar has a long history of mining and is a source of Australia's copper minerals. Malachite is often found in copper deposits meaning that it is representative of Cobar's copper production. Malachite is known for it's vivid green colour and as a result, has many uses, such as meaning used as a dye. This makes it a valuable material and highly significant. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

This particular specimen is found in Wolgan Valley, New South Wales. It could be linked to the abandoned oil shale mining sites in Wolgan Valley such as Newnes. Newnes was an industrial complex operational in the early 20th century is now partly surrounded by Wollemi National Park. It produced motor spirit, kerosene, and gas oil. Newnes's Torbanite oil shale rock contained around 350 litres of oil shale per tonne. The Torbanite was mined by the Commonwealth Oil Corporation Ltd. Oil shale is a sedimentary rock and also a form of fossil fuel. It is often formed millions of years ago and usually contain fossilised remains of plants and/or animals. Oil shale is rich in kerogen that releases hydrocarbon when heated. These hydrocarbon can be used as an alternative petroleum or natural gas. The oil-shale rock was converted into oil by "destructive distillation"; the rock being heated until it broke down to form an oily vapour and an ash residue. Oil bearing shale is one of Australia's national assets. There are many oil companies established in Australia. It reflects Australia's rich natural resources as well as connection to the Australia's engineering and oil industry. The booming oil shale extraction businesses can be traced as far back as 1920s. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Amazonite is classed as a Tectosilicate and is part of the Feldspar group of minerals. Amazonite forms in a triclinic crystal structure and its chemical formula is K(AlSi3O8). In appearance, Amazonite can range from shades of green to green blue to blue, and often with white streaks or veining. The greenish colour is believed to come from the small amount of lead contained in its composition. Amazonite is named after the Amazon River due to its colour and similarities to another rock found along the riverbanks, although Amazonite is not actually found at or near the Amazon. Although less commonly used in jewellery today, Amazonite has been mined and used by humans for thousands of years and Amazonite jewellery from at least 2000BCE have been discovered in North Africa. Amazonite is found in many locations around the world including Brazil, Peru, Ethiopia, Canada, Russia, Mozambique, Myanmar, Pakistan, China, Madagascar, and the United States of America. This specimen most probably comes from the U.S.A., Amazonite is found in several US states particularly in Colorado, Virginia, Pennsylvania. This specimen is of both scientific and historic significance as a striking blue green example of Amazonite mined prior to 1868 in the United States of America, most likely from Colorado, Virginia, or Pennsylvania. These three states are all locations of significant Amazonite deposits. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Malachite is a green copper carbonate hydroxide mineral and was one of the first ores used to make copper metal. Malachite has been utilised as a gemstone and sculptural material in the past as its distinctive green color does not fade when exposed to light or after long periods of time. Malachite is formed at shallow depths in the ground, in the oxidizing zone above copper deposits. The material has also been used as a pigment for painting throughout history. Malachite is considered a rare gemstone in that the original deposits for the stones have been depleted leaving behind very few sources. In addition, the use of Malachite as gemstones and sculptural materials remains just as popular today as they were throughout history. It is quite common to cut the stone into beads for jewellery. The fact that Malachite has such a rich colour and one that does not fade with time or when exposed to light makes it particularly rare. Although there is no indication available of the locality from which the specimen was sourced, it is likely that the specimen was collected either in South Australia in the vicinity of the Burra Burra mines or in Victoria as part of programs of geological surveying undertaken in the Nineteenth and Twentieth centuries. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Tourmaline specimens are members of a crystalline silicate mineral group based on boron but influenced by elements including aluminium, iron, magnesium, sodium, lithium, or potassium. Specimens present a wide variety of colours and forms according to the specific mix of these elements. Tourmalines are semi-precious gemstones with many applications, including commercial jewellery production. The word 'tourmaline' derives from the Sinhalese term for the carnelian or red-shaded specimens, "tōramalli". This specimen has been classified by geologists as 'Black Schoalou/Tourmaline in quartz'. Schoalou may equate to a common black-hued type of Tourmaline associated since around 1400 with mines in Saxony, Germany near a village called Schorl (today's Zchorlau). If this specimen is part of the 'Schorl' species of tourmaline it is a member of the most common group of Tourmalines, a divalent sodium ion influenced group accounting for 95% of specimens. On assessment, it was noted that the crossed lines (XIs) of this tourmaline have been fractured and rehealed by the quartz matrix in which the tourmaline rests. This item is significant as an example of its type of gemstone and the geological processes leading to its formation.

Agate occurs when amygdales (gas pockets) form in the upper levels of basaltic lava flows. If these pockets or bubbles are iniltrated by water bearing silica in solution, the fluid dries and hardens in layers, forming round or egg shaped nodules or geodes within the rocky matrix. Agate is formed of a silica mineral chalcedony similar to quartz. Although relatively common and semi-precious, agate has been prized since at least 1450 BC - an intricately carved agate seal was found in the 2015 excavation of a grave belonging to a Mycenaeum priest or warrior near Pylos in Greece. Agate is also used in jewellery and other decorative or ritual purposes due to its often striking appearance. Quartz is found all over Australia, including Beechworth in Victoria. It is formed in deep-seated igneous rocks and crystallized through hot aqueous solutions. It can have two forms; Microcrystalline quartz or Crystalline quartz. Microcrystalline quartz is a fine grain quartz where crystalline quartz is often a large crystal. The colour of quartz can vary. These specimens were collected in Victoria in the vicinity of the Burke Museum. Victoria and other regions of Australia were surveyed for sites of potential mineral wealth throughout the 19th Century. The identification of sites containing valuable commodities such as gold, iron ore and gemstones in a locality had the potential to shape the development and history of communities and industries in the area. The discovery of gold in Victoria, for instance, had a significant influence on the development of the area now known as 'the goldfields', including Beechworth; the city of Melbourne and Victoria as a whole.The specimens are significant as examples of surveying activity undertaken to assess and direct the development of the mineral resource industries in Victoria and Australia, as well as the movement to expand human knowledge of earth sciences such as mineralogy and geology in the nineteenth century.Geological specimens of Agate and Quartz respectively; the fist-sized piece of Agate has peach/coral colouring with grey concentric patterning and the smaller piece of quartz is a uniform yellow/orange shade.

Galena occurs in a range of deposit contexts, often in metalliferous veins, such as Broken Hill, Australia; Coeur d’Alene, Idaho, United States.; Clausthal Zellerfeld, Germany; and Cornwall, England. Large deposits also replace limestone, dolomite, or occasionally organic matter, or have a contact-metamorphic origin. Galena is additionally found in cavities, brecciated (fractured) zones in limestone and chert, and in coal beds. This specimen was recovered from Broken Hill NSW and is 60% lead with 8-12 oz/silver to the ton.Galena or 'lead glance' is a grey lead sulfide and the chief ore mineral of lead. It forms isometric crystals in which the ionic lattice is similar to sodium chloride. Galena is brittle and easily weathers to secondary lead minerals, with the upper part of mineral deposits often containing cerussite, anglesite, and pyromorphite. It usually contains silver, which is mined along with its lead content. Other commercially important minerals that form in close association with galena are antimony, copper, and zinc. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Anthracite typically occurs in geologically deformed areas due to extreme heating – with temperatures ranging from 170 to 250 °C – caused by igneous intrusions or high geothermal gradients. It is most commonly found in northeastern Pennsylvania in the United States; however, smaller amounts are also found in Australia, China, eastern Ukraine, South Africa, western Canada, and other countries. This specimen was recovered from Tasmania and is 85-95% carbon.Anthracite is the mineral name for hard coal and is the least plentiful of all coal types. It is clean to the touch and, when polished, is used for decorative purposes. Before natural gas and electricity, anthracite was used for domestic heating as it produces little dust, burns slowly, and gives off a minor amount of smoke. However, it is also limited in abundance and expensive. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

New Zealand Greenstone, also called Pounamu is found on New Zealand’s South Island in riverbeds and boulders, and colours vary depending on the source, but always include green tones. It is a form of the mineral nephrite, also known as jade, and is a tough stone with a crystalline structure, made up of calcium magnesium and iron silicate. Its hardness means it is ideal for carving, and has been used for this purpose throughout history, especially by the Maori people of New Zealand. Greenstone features heavily in Maori mythology, and the traditional name for the South Island, Te-Wai-Pounamu, literally translates to waters of greenstone. Wearing of Greenstone pendants with different carvings is practiced by Maori to represent connection to land and ancestors, or to endow the wearer with certain attributes. The sticker on the base of the specimen identifies it as a product of Hokitika Jade Company. The company, which was active in the 1970s, sold jade and greenstone specimens and ornaments. Hokitika, which started life as an 1860s gold rush town, is the origin of most nephrite found in New Zealand, and the centre of the Greenstone carving industry. The object has scientific and research potential as part of the Burke Museum's Geology Collection, and as and example of New Zealand Greenstone. It also has spiritual significance for it's role in Maori beliefs and communities, where it is both traditionally worn and features in mythology. As a valuable stone regularly used in carving and jewellery, it has aesthetic significance. Sticker on base: "N.Z.

It is not known where this opal originated. Common Opal is formed from silica-rich water entering the earths crust and hardening into a gel of water and silica-spheres, layered through the specimen. Common opal differs from precious opal in colouration and appearance, with precious opal including more colours, and having a translucent or glossy appearance, where common opal shows less colour and is typically opaque. It scores high on the Mohs hardness scale, and is common throughout the world, especially in Australia, where it is far more prevalent than the highly-prized precious opal. Australia is also the highest producer of opals in the modern world. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Selwynite is a fine-grained, compact green rock made primarily of chromian muscovite (fuchsite) and diaspore. Corundum and fuchsite can occur together in the form of massive aggregates or nodules. Often, copper carbonates are found as earthy films or tiny crystals in joint planes. The mineral name honours the late A. R. C. Selwyn, founding Director of the Geological Survey of Victoria. The particular specimen, a mottled green stone suitable for carving was recovered and found in Heathcote, Victoria, Australia. The rarity and qualities of this mineral attracted commercial mining, which was not successful, but traces of the mine shafts still exist today, and it is still highly valued by mineral collectors.Selwynit is considered to be one of the rare forms of rock because it is composed of phosphate minerals containing zirconium. This is an extremely rare combination found in nature. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

A granular metamorphic rock, marble is derived from limestone or dolomite and composed of calcite or dolomite interlocking grains. Heat and pressure from overlying sediments form it from limestone buried deep in Earth's crust. Graphite, pyrite, quartz, mica, and iron oxides can affect rock texture and colour. This specimen was found in Carrara, Italy. Carrara marble is the most common marble found in Italy, and it gets its name from the region where it is located. The marble was also called Luna marble and was used as a decorative element in buildings and sculptures. It has been quarried since Roman times in the Lunigiana, the northernmost tip of Tuscany, just outside the city of Carrara in the province of Massa and Carrara.Marble is one of the most popular and expensive rocks used in sculpture, architecture, interior decorations, statues, table tops, and novelties. It is available in various colors and textures depending on the chemical composition. The strength of the rock and its ability to hold finer details have made it a favorite among designers. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Fluorite comes in a variety of natural colours and crystal formations and glows under ultraviolet light (the word 'fluorescence' comes from the same etymological source). In its pure form, calcium fluoride, it is a colourless combination of the elements calcium and fluorine, but gains its colour from trace elements that infiltrate or replace calcium within its crystal structure during its formation. Although fluorite crystals polish well and can achieve a high level of lustre, the mineral is very soft (4 on MOHS hardness scale) so it is unsuitable for use in rings and must be handled and stored carefully if used in other forms of jewellery. Most crystals of the mineral are too coarse for decorative purposes but have been mined under the name fluorspar for a variety of commercial and industrial purposes. These include the production of hydrofluoric acid, smelting metal alloys, producing glazes and ceramic finishes and use in medical and dental products. An existing label for this specimen indicates that its origin or collection-point was 'probably USA.' Fluorspar, the form of fluorite used commercially and industrially, was mined in significant quantities in the counties of Hardin and Pope in South-Eastern Illinois throughout the Nineteenth and Twentieth Centuries. Fluorite was made Illinois' state mineral in recognition of its contribution to the state's identity and economy. The specimens are significant as examples of surveying activity undertaken to assess and direct the development of the mineral resource industries, as well as the movement to expand human knowledge of earth sciences such as mineralogy and geology in the nineteenth century.The specimen is a piece of purple shaded fluorite (also known as fluorspar), the mineral form of calcium fluoride.

Bituminous coal is the most common type of coal, abundantly found in ancient coal deposits which can be dated back millions of years. Often referred to as soft or black coal, this specimen exhibits a high carbon content, ranging from 76-86%. It also holds a relatively high energy density (27 MJ/kg) meaning that it releases significant amounts of energy when burned. Bituminous coal is most commonly used for electricity generation, as well as in the production of steel. This particular piece of coal was collected as part of the Geological Survey of Victoria in the nineteenth century. It originates from Cape Paterson, a seaside village located in South Gippsland, Victoria (located on Bunurong Country). The discovery of bituminous coal in this locality was first made in 1826 by explorer William Hovell. More discoveries were gradually made over the following decades and in 1859 the Victorian Coal Company commenced the first active coal mining operations in the state by sinking a number of shafts and bores near the area of Cape Paterson. Evidence of this coal-focused past can be found today at the State Coal Mine Museum in the nearby town of Wonthaggi. This specimen is significant as it was collected from the locality of Cape Paterson in Victoria, an area that has since become historically instrumental in the mining of coal and other substances in the state of Victoria. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Malachite is a copper carbonate hydroxide mineral. It has a chemical composition of Cu2(CO3)(OH)2. It often forms within limestone where a subsurface chemical environment favourable for the formation of carbonate minerals can occur. It is a substance that can be found in many different parts of the world including: Australia, USA, Russia and the Democratic Republic of Congo. Malachite has historically been used to produce copper, with mining of the mineral dating back over a period of four thousand years. Due to its beautiful green colourations, it is also commonly used for aesthetic purposes such as in the production of sculptures and jewellery. This particular specimen was collected from the town of Burra, South Australia as part of a geological survey undertaken during the nineteenth century. The locality (located on Ngadjuri Country) has a long history of mining, particularly in copper mining, as the area is rich in copper deposits. The first significant discovery of this was made in Burra (Burra Burra Mine) in 1845 and, at the time, the mine was the largest and richest of its kind in the world, producing nearly five percent of the total world copper output. This specimen is significant as it is considered to be a rare gemstone, as many of the original deposits for the stones are significantly depleted, leaving behind very few sources. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Laterite refers to both a rock and a soil type that is rich in clay, as well as Iron and Aluminium. It is created during a process that is called laterization, where high heat and seasonal heavy rainfall cause there to be wet and dry periods, which over time hardens the soil into rock. Because of this, most laterite is formed between tropics of Cancer and Capricorn. The iron oxide in laterite is what gives it it’s orange-red colouring. The largest religious complex in the world, Angkor Wat in Cambodia, is partially constructed of laterite, particularly its foundations, as laterite is porous and allows rainwater to drain. This specimen of laterite was collected from the Democratic Republic of Congo while it was colonised by Belgium in the 19th century. Laterite forms in many parts of the world, particularly between the tropics. It is used both for ore and as a building material, and comparing specimens from different parts of the world allows us to document the different compositions that this mineral can have when formed at different locations. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria.

Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.a palm-sized solid iron-aluminium oxide mineral specimen in shades of brown, orange and greyburke museum, beechworth, geological, geological specimen, laterite, laterite specimen, geology

Montmorillonite is a type of clay composed of aluminium silicate that forms very small particles that are not well-bonded to one another. This is why it is so soft. When in the presence of water, all types of clay swell. Montmorillonite swells even more than most types of clay, which is why it is often chosen over other types of clay in its practical uses. Montmorillonite has many different practical uses, including in the mining industry, as a soil additive, as a sealant, as a desiccant to draw water out of the air, to clean ponds, to make kitty litter and in cosmetics. Montmorillonite is a common mineral and, despite being named after Montmorillon, France, can be found all over the world, including many deposits in Australia. It is not known where this particular specimen originates from. Montmorillonite is an economically and socially significant material with a wide variety of uses. Having samples of common and important minerals allows collections, like the Burke Museum, to have a more complete view of the land on which they are located, and therefore a more complete view of heritage. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

This specimen is Cassiterite in Quartz. Cassiterite is a tin oxide metal that forms in thin crystals which can have a beautiful lustre. Quartz is made of silicon dioxide, also known as silica, and is one of the most common minerals on earth. Cassiterite has been a fundamental source of tin ore for humans throughout history, including today. Tin is an important metal that has a wide variety of human uses in different areas, from dying fabric, to making mirrors, and their most well-known use ‘tin’ cans. Tin cans are primarily made of steel and are coated with tin in order to take advantage of tin’s property of being non-corroding. This is a massive step in the history of food preservation. Tinned food first reached Australia in 1815 with early settlers, and it began to be manufactured here in the 1840s. It was incredibly popular, and was a highly exported product, which would be a contributing factor to the ‘tin mining boom’ of the early 1880s. This specimen was collected at Jingellic, New South Wales, in about 1852. Although the Goldfields of the 1800s are much more well-known, tin mines existed alongside the gold mines which began in the mid 19th century and extended almost one hundred years, to the mid 20th century. Specimens like this would have been used as evidence to justify tin mining operations in the region as an investment. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study. The Geological Survey of Victoria was headed by British geologist, Alfred Richard Cecil Selwyn (1824-1902), who was responsible for issuing over 60 geological maps during his 17 years as director. These maps were all hand-drawn and coloured and became the benchmark for accuracy for geological mapping. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.

There are 17 opal fields in Australia. This opal bearing stone was found in Lightning Ridge, NSW over what is known as the Great Australian Basin. This basin was formed and covers an area of 1.7 million square kilometers in eastern Australia in the Cretaceous period. This basin used to contain an inland sea, which provided an environment where silcrete eventually formed when water levels changed. This eventually seeped into other structures, and eventually hardened and formed opal. Lightning Ridge has a population of around 2000 people, with about 80 000 visitors every year. It is a historic mining town, and is known for its deposits of a rare black opal. Mining started in the area in the late 1800s, early 1900s when the black opal was discovered. This opal-bearing stone is of social and historical significance. It is from Lightning Ridge, which is well-known for being a large producer of opal stones, most famously black opal. The history of the period dates back to 140 million years, with the discovery of black opal in the early 1900s causing interest in the area.

It is made up of andalusite. Andalusite is a rock-forming mineral, sometimes found in granite or schist. It is often used to make glass, ceramic products, chemicals, and heat-resistant bricks as it can withstand high temperatures without changing. The chiastolite contains particles of graphite, which arranges in geometric patterns. When crystal growth occurs in the rock, the granite particles concentrate at crystal interfaces and can result in cross shapes. These ‘cross stones’ have been valued and used for their spiritual or religious meaning and used as charms, gems, or amulets. Chiastolite was first discovered in 1754, seen in a description in a published book by a palaeontologist, Franciscan priest, and Spanish author, Jose Torrubia. Deposits have been found in Australia, France, the USA, Chile, Canada, Spain, Brazil, Sri Lanka, and Russia. Deposits have been found in Western Australia and South Australia. This particular specimen was found in Bimbowrie, South Australia. Other chiastolite specimens have been found in Bimbowrie, along with jasper, quartz, and aventurine in the form of rolled pebbles or schist. This chiastolite specimen is socially and historically significant. It is a very rare sort of andalusite mineral. It is from one of only two locations where it is regularly found in Australia. The carbon cross has made it an important religious symbol in the past. Its ability to withstand high temperatures has made it a common ingredient in heat-resistant bricks and ceramics today.

This specimen was donated in 1868 by Alfred Selwyn. Olivine is typically found in basic and ultra-basic igneous rocks around the world, in a variety of colours including yellowish green, olive green, greenish black and reddish brown with a transparent to translucent diaphaneity. The luster of the specimen is vitreous, the luminescence non-fluorescent and when fractured the mineral is very brittle producing small, conchoidal fragments. Chromian diopside is normally found in small sizes as the larger the size of the mineral the darker the colour is, almost black rather than green. Chromium is the element that gives chromian diopside and emeralds their rich green colour. Diopside is found across the world in multiple colours however gem-quality chromian diopside is mined in Siberia, Russia and prominent within the jewellery industry as a more affordable substitute to emeralds. Chromium-bearing diopside has been located across Australia. Chromium-bearing Diopside is located across the world found in North America, parts of South America, and across Australia, Africa, Europe and Asia. Chromium-bearing Diopside is mined in Siberia, Russia and is sold as a commercial substitute for emeralds. The stone is often turned into jewellery. This item is one of many geological and mineral specimens that constitute a broader collection obtained from various regions across Australia (as well as some international locales) and generously contributed to the Burke Museum between 1868 and 1880. A significant portion of these specimens originated from Victoria and were acquired as a result of the Geological Survey of Victoria, initiated in 1852 during the Gold Rush era. The primary objective of this survey was to investigate and chart the geological characteristics of Victoria. The procurement of geological specimens played a vital role in advancing our comprehension of the Earth's scientific composition and was instrumental in supporting research and educational institutions throughout Australia, including the Burke Museum, in their efforts to foster further exploration and study.

This glass slide captures the unveiling of the two cannons at Queen Victoria Park which were secured by Sir Isaac Isaacs and presented to Beechworth in 1901. In the foreground, elegantly dressed ladies and dapper gentlemen can be seen gathering around the park's iconic rock, with excited children looking on from the sides. Atop of the rock stands an intricately designed gas lamp that has since been removed but evidence of its existence still remains. The unveiling of these two cannons would have been a celebratory affair for those in attendance, marking a momentous occasion for Beechworth residents that was captured in this lantern slide. Sir Isaac Isaacs was an influential figure in Beechworth, having grown up and studied there. He began his education at the Common school and eventually graduated as dux of the Beechworth Grammar School. His commitment to public service was evident early on and he was elected to the Legislative Assembly in 1892, representing Bogong, a district which included Yackandandah and Beechworth. During his time in office he pushed for better education, healthcare, employment opportunities and housing for the people of Beechworth. Lantern slides, sometimes called 'magic lantern' slides, are glass plates on which an image has been secured for the purpose of projection. Glass slides were etched or hand-painted for this purpose from the Eighteenth Century but the process became more popular and accessible to the public with the development of photographic-emulsion slides used with a 'Magic Lantern' device in the mid-Nineteenth Century. Photographic lantern slides comprise a double-negative emulsion layer (forming a positive image) between thin glass plates that are bound together. A number of processes existed to form and bind the emulsion layer to the base plate, including the albumen, wet plate collodion, gelatine dry plate and woodburytype techniques. Lantern slides and magic lantern technologies are seen as foundational precursors to the development of modern photography and film-making techniques.This glass slide captures social and historical significance as it represents a moment of celebration for Beechworth residents and symbolises an important milestone in the town's history. This lantern slide stands testament to a special moment in Beechworth’s history and its significance continues to be remembered today. It is also an example of an early photographic and film-making technology in use in regional Victoria in the time period.Thin translucent sheet of glass with a circular image printed on the front and framed in a black backing.

This image shows a pathway in the gardens adjacent to Beechworth's Town Hall at the beginning of the Twentieth Century, around the time of Australia's Federation. The pathway leading to a circular rotunda or covered seating area with a steep conical roof is lined with shrubs set in grass verges that appear to be covered with snow. It is unknown whether the snowfall or a factor to do with the gardens occasioned the taking of the image, which at the time may have been an exotic practice. Climate records going back to 1908 indicate that snow in winter is not unusual due to Beechworth's elevation and orientation, and the Town Hall itself was built in 1859.

Beechworth's Anglican Church, Christ Church St Peter and St Paul, has served the Beechworth community since 1858 in its present form, following its beginnings in a tent in 1855. The Victorian branch of the National Trust classified the building as regionally significant in 1959 and the organ as of significance to the nation in 1992. Building a place for Anglican worship was a priority in the early days of Beechworth's settlement as the town was a site of regional administration due to its association with the economic and social expansion of Victoria during the Gold Rush period. The Church garden features several significant trees monitored by the Beechworth Treescape Group, including a cork oak growing near the Ford Street entrance, an Atlantic cedar, a bunya or bunya-bunya pine and two kurrajongs. Some of these long-established trees may be visible in this lantern-slide image.

This image shows the gorge adjacent to Beechworth in approximately 1900. Although the exact location of the photograph is yet to be determined, the present-day Beechworth Gorge Walk includes views of the Cascades at the point at which Spring Creek flows into the valley on the level below. Gold-sluicing techniques in use in the town during periods of active gold extraction may have altered the landscape since the photograph was taken, however. In the 1850s a mill was built at the top of the Spring Creek falls by Russian-born Louis Chevalier, brother of artist Nicholas Chevalier. The mill supplied the town with lumber that supported the town's initial construction boom.

This image shows a semi-aerial view of a property along a river adjacent to Beechworth in approximately 1900. The photographer has capitalised words in the label, indicating that 'The Precipice' may have suggested a particular rather than a general vantage point to local people at the time. Although the exact location of the photograph is yet to be determined, Beechworth Gorge is popular today with hikers and nearby Mt Stanley is noted for its views.

This image appears to show nurses at what is now the Mayday Hills Mental Asylum arriving for work in approximately 1900. These individuals are part of a long history of nursing in Beechworth. Three medical or social welfare facilities opened in the mid-1800s as part of a push by the township to become a regional centre for Government services. These were the Ovens District Hospital (opened in 1857), the Ovens Benevolent Asylum (opened in 1863), and the Beechworth Mental Hospital (opened in 1867 and renamed Mayday Hills Hospital at Centenary celebrations in 1967). It was recognised that the unsettled living conditions, poverty and relative isolation of the Goldfields environment could produce 'mental disturbances' which required local treatment facilities as services in Melbourne were too far away. Carole Woods' publication 'A Titan's Field' describes activities undertaken by patients at Beechworth Mental Hospital as including monthly balls and occasional concerts as well as work to make the facility self-supporting such as farm work and making clothes. She mentions a report in 1870 that the approximately 300 patients were clean and neat with 'no-one in restraint or seclusion' but that by 1905 the organisation had 623 patients which placed strain on building infrastructure such as heating and water supplies, leading to high turnover of nurses and other issues. A program of building works to extend and improve facilities followed over subsequent decades.
