This specimen was recovered from Philip Island in Victoria. Chalcedony is composed of Quartz and Silicon Dioxide represented as SIO2. It has and is still used as a gemstone for thousands of years. This is an excellent specimen Chalcedony that shows its aesthetic properties. 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.

Geological specimen - Malachite in Conglomerate, Unknown
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.

Geological specimen - Common Opal, unknown
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. 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.

Geological specimen - Common Opal, Unknown
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.

Instrument - Weights and measures, Collection of Nested Cup Troy Weights, (23093.3) 1826
The nested cup weights were designed to make the transport of weights, essential items in most commercial transactions, more convenient. This idea goes back to Roman times. In the nested cup form, a series of weights shaped into cups are set one into the other. Each cup fits precisely into the next, larger sized cup which each larger example weighing exactly twice that of the one previous. The Troy weight system was used for precious metals and gemstones.7 x Brass troy measures of various sizes.

Geological specimen - Precious Opal
In Australia, precious opal is found in Cretaceous age sandstones and mudstones. These sedimentary rocks were deeply weathered and this weathering released silica into the groundwater.Australia is the only part of the world where opalised animal and plant fossils have been found. Opal artefacts several thousands of years old have been discovered in East Africa. As early as 250 BC the Romans prized opals, thought to have come from mines in Eastern Europe, the ancient world's main source of opals. There are many aboriginal dreamtime stories that feature opal. Australian opals discovered during the late 1800's found little favour with European markets but their commercial value increased in the 1900's and in 1932 Australia took over as the major producer of opals in the world and remains the largest producer to this day. Opal is found around the world (Brazil, Mexico, Honduras and the western US) however Australia produces 95% of the world's precious opal and it is our official national gemstone. Opal was first mined commercially at Listowel Downs in Queensland in 1875 and later at White Cliffs in NSW. Today, Coober Pedy (SA) is the main producer of white opal, though in recent years this field has expanded and all types of opals are found. Other centres in SA include Andamooka and Mintabe. Lightning Ridge (NSW) is renowned for black opal and formerly White Cliffs was a large producer of high quality opal. Boulder opals (opals in concretionary ironstone) are mined in Queensland from numerous localities in a zone extending from the Eulo and Cunnamulla district in the south and northwest for a distance of over 700 km to Kynuna in the north. The towns of Quilpie, Yowah and Winton are the main opal mining and wholesale centres. Opals are considered gemstones and have been used in jewellery for thousands of years.Throughout much of history, opals were actually believed to be good luck. The Romans thought that opals were one of the luckiest gemstones and a symbol of hope. In the Middle Ages, opals were believed to be bestowed with all the positive properties of coloured gemstones due to its rainbow-like play of colour. Finally, there is a superstition that you should not wear an opal unless it is your birthstone otherwise misfortune will befall you. This, of course, is far-fetched, but the notion could have been promoted in the late 19th and early 20th Centuries by diamond traders who were trying to increase sales of diamonds and deter people from buying opals. Possibly related to this is the thought that you should set opal jewellery with diamonds as their powers of good fortune will override any negativity held by the opal. The great majority of opal does not show play of colour and is called common opal or potch however this is not the case with a precious opal. Opal is a precious gemstone, like rubies, emeralds or diamonds. Opal is rare, and it is expensive to prospect and mine for.Silica is one of the most common minerals on the planet, but precious opal is very rare – far more rare than diamonds. Precious opal is rare because the natural processes that create it rarely occur.Most (at least 95%) of the opal found by miners is common opal without gem colour. In Australia we call it potch. It can be white, grey, black or amber coloured. Even when a miner finds gem-coloured opal, most of it can’t be cut into gemstones because it’s too thin, or sandy. 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.It is not known where this opal originated, except that it is probably from Victoria, as it has been recorded from many localities in the State. Common Opal is formed from silica-rich water circulating through rocks near the Earth’s surface. It consists of minute spheres of silica arranged in different ways. In common opal, the spheres are of different sizes and randomly arranged, unlike in precious opal where the spheres are of similar size and uniformly arranged in three dimensions. These differences account for common opal generally being translucent to opaque and without the play of colours, or opalescence, displayed by precious opal. Common opal is found in many localities and different geological environments throughout Australia and the world. Precious opal requires special conditions to form and is much less common. Australia produces most to the world’s precious opal. burke museum, beechworth, indigo shire, beechworth museum, geological, geological specimen, precious opal, opal, brazil, mexico, honduras, queensland, coober pedy, gemstones, jewellery, play-of-colour, light blue -

Purchased by Mr. & Mrs. H. N. Lord in 1970. Cloisonné, a French word meaning "enclosed", is a metal-working technique. It is an ancient technique for decorating metalwork objects. The resulting objects can also be called cloisonné. The decoration is formed by first adding compartments or cells to the metal object. This is done by soldering or sticking silver or gold wires or thin strips placed on edge. These are visible in the finished piece, separating the different compartments. Coloured enamel is the usual filling for the cells. Cloisonné enamel objects are worked on with enamel powder made into a paste, which then is fired in a kiln. In older times inlays of cut gemstones were often used. They were decorated with geometric or schematic designs, with thick cloison walls.

Jewellery, 3 men's lapel pins, c1900
A tie pin is a neckwear controlling device, originally worn by wealthy English gentlemen to secure the folds of their cravats. They were first popularized at the beginning of the 19th century. Cravats were made of silk, satin, lace and lightly starched cambric, lawn and muslin, and stickpins were necessary accoutrements to keep these expensive fabrics in place and safe. Stickpins commonly used pearls, and other precious gemstones set in gold or other precious metals and were designed specifically for their owners. By the 1860s, wearing cravats had been embraced by the English upper middle classes with a consequently lower quality of materials and designs used in both the neckwear and in the stickpins used to keep it in place. By the 1870s Americans had embraced stickpins and designs were mass-produced. 3 men's metal lapel pins with coloured glass inserts 1 yellow 2 red jewellery, tie-pins, male neckwear, moorabbin, brighton, early settlers, pioneers, cheltenham -

Personal Effects,men's shirt studs, c1900
A shirt stud is a decorative fastener that fits onto a buttonhole on the front of a pleated shirt, or onto the starched bib of a stiff-front shirt. Such shirts have special buttonholes solely for shirt studs. A shirt stud may be fashioned from alloys, precious metals, and gemstones—materials uncommon to buttons sewn on shirts. The stud may have an inlay, such as of pearl or onyx. Dress code of the modern western world reserves shirt studs for men's formal wear and some semi-formal occasions. In the western world, shirt studs were first used in the mid-19th century, when some shirt fronts were too stiff to close with buttons. So remains the case for the heavily starched, modern full dress shirts worn with white tie.

Geological specimen - Unknown, possible Carnelian Agate or Chalcedony
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 -

Geological specimen - Tourmaline in Quartz, Unknown
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.

Geological specimen - Garnet (red crystals) in galena (silvery metallic) and green feldspar, Unknown
Garnet is a popular gemstone used in jewellery due to its hardness and durability. There are about 5 varieties of Garnet, which distinguish the colour of each stone. In Australia mostly Pyrope and Aimandine varieties are found; Pyrope, which is blood-red to black and Aimadine, which is brownish-red to black. Other varieties are rarely found in Australia. The garnets visible in this specimen are likely Pyrope. Galnea is the natural mineral form of lead sulphide and has had various uses throughout history; from makeup to car batteries. It was first mined in South Australia in 1841. Green feldspar is an amazonite mineral, a variety of the potassium feldspar called microcline. This particular mineral is considered uncommon. It has been used in jewellery throughout history. It is likely that this specimen was found in Broken Hill, NSW, presumed due to findings of specimens with similar combinations. Broken Hill is Australia’s longest-lived mining city. The city’s fortunes have come and gone against an extreme economic background of boom and bust which continues today.This geological specimen is a rarity, given that is formed of three distinct minerals and the richness of colour that remains visible in this item attests to the strength of each structure. As we cannot pinpoint exactly where this specimen was found further research can only strengthen what is known about mining within Australia. As such the item is significant due to its scientific rarity and its ability to represent three specimens in one. A solid palm-sized mineral that features shades of grey, red and green. garnet, galnea, green feldspar, minerals, mining, rare specimen
