This particular specimen was recovered from two hundred feet down in the Golden Mile in Kalgoorlie, Western Australia. The Golden Mile, named after the estimated sixty million ounces of gold worth around one hundred billion dollars, was the birthplace of the largest gold rush in Australia almost one hundred and thirty years ago when William Brookman and Samuel Pearce leased the Great Boulder mine. The Golden Mile is also the home of the Super Pit, Australia's most well-known mine.The majority of gold deposits will form as a native metal, however, on occasion, it can form a compound with another element, in this case, sulphur. Therefore, this specimen is a rare example of gold naturally forming into a compound mineral with sulphur. 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.A small gold-sulphide ore mineral specimen in shades of silver and grey with flecks of gold. Precious metals are often found in Sulphide Ores, as sulphides usually bind to these metals. They are also extremely symmetrical in crystaline form. Gold-Sulphide Ore occurs when gold forms a natural compound with other elements. In this form, gold can be present in one of two ways. It can be fully immersed in the sulphide, or a portion may be partially free. This specimen has minimal gold visible, with only a few flecks being partially visible.burke museum, beechworth, indigo shire, beechworth museum, geological, geological specimen, mineralogy, gold-sulphide ore

This specimen originated from Mount Lyell on the west coast of Tasmania, where a large group of open cut and underground copper-silver-gold mines began operating in 1883. Between 1893-1994, the Mt Lyell Mining and Railway Company were responsible for operations. The Mt Lyell copper-gold mines produce some excellent crystallised specimens of chalcopyrite and other minerals. The deposits are generally considered to be of Cambrian volcanic origin, but there are indications of Devonian granitic influence on the ores, plus local remobilisation during Devonian deformation. Over 120 million tonnes of ore was produced from several workings, including the main Prince Lyell mine and the North Lyell mine, which was also of great importance. The Mount Lyell mines have a long history of human and environmental disasters, including the 1912 North Lyell fire that killed 42 miners, and two separate incidents in 2013 in which three people lost their lives. The environmental impacts from this complex of mines are extensive, with waste tailings and heavy metal contamination flowing directly into the King and Queen River catchments. In 1954, the eminent Australian historian, Geoffrey Blainey, published 'The Peaks of Lyell' which delves into the history of the 1912 North Mount Lyell Disaster.Chalcopyrite does not contain the most copper in its structure relative to other minerals, but it is the most important copper ore since it can be found in many localities and occurs in a variety of ore types. The brassy-yellow colours in Chalcopyrite mean it is often confused with pyrites and gold, leading to use of the term, "fool's gold." Chalcopyrite has been the primary ore of copper since smelting began five thousand years ago. 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.

Gold usually is found as a native metal, but it also forms minerals with tellurium, sulphur, or selenium. The gold-bearing minerals that contain tellurium are called tellurides. Kalgoorlie, Western Australia contains greater than 1500 tonnes of gold.Seventy to seventy-five percent of the deposit occurs as native gold, but a further twenty percent appears as tellurides. What remains is in the form of 'invisible' gold. Extracting gold from telluride minerals, such as calaverite, which contains around forty-two percent gold, has produced approximately three hundred tonnes of gold. Prior to 1896, rocks containing tellurides were not recognised as rich gold ores, and were discarded.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 from Broken Hill, NSW. Galena is a natural mineral form of lead sulphide and is often found associated with sphalerite, calcite, and fluorite. Galena is an important lead ore mineral, and, in some regions, it is also an important mineral associated with silver ore. Sphalerite is a sulphide mineral that is the main ore of zinc. Rhodonite is an uncommon mineral once used as an ore of manganese in India, however today the scarcity and fragility of the crystals mean it is primarily used as lapidary materials or mineral specimens. In 1883, Charles Rasp who was a boundary rider at the time, discovered what he thought were deposits of tin but were in fact samples of silver and lead. He and six others went on to set up the first mining company in Broken Hill (BHP). The ore body became the largest and richest of its kind in the world mining ore worth more than 42,000 pounds in its first year. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study. Galena contains lead and silver, Sphalerite contains zinc.

This specimen was found in Cape Patterson, Vic. Cape Paterson is a cape and seaside village located near the town of Wonthaggi, 132 kilometres southeast of Melbourne, in the Bass Coast Shire of Gippsland, Victoria, Australia. These dark, fossiliferous Mudstones were deposited in slow-moving water associated with sedimentary basins & continental shelves. They are rich in carbon which makes them almost black. This is typical of an anoxic, reducing environment such as deep water or stagnant conditions where carbon-rich material would remain unoxidised during subsequent deposition & diagenesis. it has an imprint of a leaf in the rock itself, displaying the fossil of the plant. This specimen is unique due to the leaf impression within the stone itself. Imprint fossils are formed from an organism moving in some way, leaving behind a trace or track. These tracks are preserved when the clay/silt dries slowly and is covered by other sediment. Plants can also leave imprint fossils when they are covered by sediment. The leaf tissue degrades, leaving an imprint of where the leaf once was.

This specimen was found in Harcourt, Victoria. Harcourt is a small historic gold rush town located in a valley at the foot of Mount Alexander (741 m) in the Central Highlands of Victoria. In recent times the goldrush origins of the town have been replaced by a district known for apples, cider and wine. The Traditional owners of Harcourt are The Dja Dja Wurrung people. Granodiorite is a coarse-grained intrusive igneous rock similar to granite, but containing more plagioclase feldspar than orthoclase feldspar. Granodiorite has greater than 20% quartz by volume, and between 65% and 90% of the feldspar is plagioclase. This piece is of significance due to its provenance in Harcourt, Vic. Granodiorite is commonly produced in volcanic arcs, and in mountain buildings where it emplaces as large batholiths in mountain roots. Granodiorite is the plutonic equivalent of dacite.

This particular specimen was found in the Moorabool Slate quarries in Victoria. The Moorabool Slate quarries was established in the 1860’s by a company of Welshmen with a crew of six who purchased land by the riverside to mine for slate. Under the promise of adding to existing recourses the crew mined the slate which was used for paving and roofing. Slate is a fine-grained, low-grade metamorphic rock that is formed by the transformation of mudstone, shale or sometimes volcanic ash under low pressure and temperatures. It dark colour is due to carbonaceous material or to finely divided iron sulphide. It is believed that Evan Rowlands and Theophilus Williams of Ballarat were the first to discover the slate veins. Slate is a one of the most common natural stones in general use. Being used as paving, flooring, roofing and more. However, its history of being mined in Australia is not common as it is considered that the best places to mine slate is Spain and parts of the United Kingdom.

This specimen was recovered from Ceres West of Geelong, Victoria. Greenstone is the name for any metamorphosed basic igneous rock (in the case of this specimen, Gabbro) that gains its greenish colour to the presence of the minerals chlorite, actinolite, or epidote, hence the term 'green' and 'stone'. Greenstone is often formed through metamorphsis along a convergent plate boundary. In the rock cycle (the series of processes that creates the various types of rocks) there are identified three different types of rocks, which are the sedimentary, the igneous and the metamorphic. Metamorphic rocks started out as sedimentary, igneous or earlier metamorphic rocks but changed from their original condition under the effect of high heat, high pressure or hot, mineral-rich fluid. However, if pressure or heat is too high, then the rock will melt, resulting in the formation of an igneous rock. The name used to describe these types of rocks reflects this specific inherent trait of change, since the word “metamorphic” derives from the Greek word “metamorphosis”, meaning “change of form or structure”. Metamorphic rocks form in the Earth`s crust but can be also found on the surface, due to elevation of the Earth`s surface. They are divided into two categories: the foliated metamorphic and the non-foliated metamorphic rocks. Gabbro is a highly useful mineral that is often polished to create cemetery markers and kitchen benches. It is notable for its qualities of durability, being able to withstand extreme elements and wear. Whilst not rare, Gabbro is of great utility and has been highly desirable for its qualities.

This specimen was recovered from Moonambel, Donkey Hill, Victoria. Established in the early 1860's, Moonambel is a small town in the Pyrenees region of the Australian state of Victoria. In the 1850s the location of Moonambel was part of the ‘Mountain Creek’ pastoral run, but in 1860 reports began to appear of a gold-rush at McKinnon’s ‘Mountain Creek’ station. By 1861, a township had developed on the diggings site, and on 21 October 1861 the “municipal district of Moonambel, on Mountain Creek” was proclaimed. The name 'Moonambel' is believed to be an aboriginal word meaning 'hollow in the hills'. Slate is a stone with a fine grain that is noted for its persistent strength and ability to naturally split into slabs. It forms under low temperatures and is most often created from clay. Pyrite is a crystallising compound that occurs naturally in grey and blue-black slate that is colloquially referred to as slate-rust as it resembles regular rust. 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 was recovered from Adelong, NSW. The initial discovery of gold at Adelong by a Mr Williams took place in 1857. Much of the area is underlain by granitic rocks, while at Adelong itself a prominent norite intrusive body occurs. To the west of Adelong is a belt of intermediate to mafic igneous rocks and sediments which extends from Batlow in the south to at least as far north as the Snowy Mountains Highway. Around 26 tonnes of gold was found at the Adelong goldfield from its discovery in the 1850s until the last miners left in the 1940s. Pyrite has the formula of FeS2 and forms as an isometric (cube) form. It is a common occurring material and is often mistaken for gold, now colloquially known as ‘fool’s gold’. Pyrite that has strongly crystallised is considered stable, but the mineral has the potential to oxidise and decay.

‘Ropy lava’ is known for its sculptural and layered qualities. It occurs in specific lava flows that are slow moving and slow cooling, allowing for unique formations to be created out of the motion. Ropy Lava is a flow that has a hardened crust with molten material underneath, the tension between these states is what creates its characteristic form. The brown/red hue of the stone is an indication of age, as it is oxidised iron deposits. This rock deposit is thought to be sourced from the area by Talbot, in western Victoria. This area has a rich mineral history and experienced the gold rush in the 1850's. The traditional owners of this area are the Dja Dja Wurrung people.This geological specimen shows the conditions in which the Australian landscape was created as well as provides an indication as to how these events occurred. It is representative of a common natural process that contextualises the formation of Australia with the formation of other landmasses.

Although it is not known where these specimens were collected, 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. 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. The term carnelian primarily refers to the reddish shading of the stone; whether the stone is termed an agate or chalcedony type is often influenced by the degree of colour banding the specimen shows. 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.Three small geological specimens that appear visually consistent with images of rough or unpolished Carnelian Agate or Chalcedony. geological specimen, geology, geology collection, burke museum, beechworth, indigo shire, north-east victoria, gemstones, agate, carnelian

Quartz is an extremely common mineral to find across the world. Quartz can have two forms; Microcrystalline quartz or Crystalline quartz. Microcrystalline quartz is a fine grain quartz where crystalline quartz is often a large crystal. This specimen is a crystalline quartz. Made of silicon oxide, this specimen is called smokey quartz crystals because of its brownish colour. However, the colour of quartz can vary. In addition, quartz are formed in deep-seated igneous rocks and crystallized through hot aqueous solutions. This type of crystal can be found all over Australia, including Beechworth in Victoria. Other places quartz can be found is the Ashburton River area in Western Australia, Marlborough in Queensland, the Lune River area in Tasmania and Kingsgate in New South Wales. This specimen is significant because it is common to find this kind of mineral. While the location of where this specimen was originally from is unknown, it highlights the many places in Australia where quartz is found. It demonstrates that quartz makes up a large portion of Australia's geology. In addition, quartz itself can vary in its colour and shape. This specimen represents one of these variations. That being smoky quartz crystals.

Common Opal is a mineraloid that is non crystallising and is classed as an amorphous silicate, the chemical composition for Opal is SiO2 nH2O. Opals can develop in weathered sedimentary rock typical in arid regions where limited water enters small gaps in the rock, and the silicate is hydrated. Common opals, unlike precious opals, do not exhibit ‘play of colour’ in which the colour appears to change depending on the angle of view. While precious opals are highly valuable and cut as gemstones for jewellery, common opals can be cut into inexpensive gemstones and are also mined for various uses including as ingredients in ceramics, insulation, fillers, and abrasives. The source of this common opal specimen is unknown, but common opals are found around the world, notable deposits are found in Queensland, South Australia, New South Wales, Peru, Kenya, Nevada, Oregon, and Mexico. This common opal specimen is of historic and scientific significance due to its donation in 1868 as part of the Geological Survey of Victoria and as a typical example of uncut common opal.

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.

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. 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.A solid hand-sized mineral with shades of brown , white and light green throughout.geological specimen, geology, geology collection, burke museum, beechworth, malachite, copper, water soluble, cobar, cobar mines, cobar mining, cobar nsw, nsw, new south wales, mining belts, ore, copper ore, malachite green, dye, green, dye industry, textile industry, desposits, canbelego, girilambone, alfred selwyn

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.

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.

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. 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.

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.

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.

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.

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.

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.
