Opals, the national gemstone of Australia, are found in several states
Lightning Ridge in New South Wales is famous for its highly prized and rare black opals, which are distinguished by their dark grey to blue-black background. The black opal is the most valuable type of opal, often worth more than some diamonds. The unique nature of carbon and iron oxide trace elements in the soil gives Lightning Ridge opals their distinctive black body tone. The small town of Jundah-Opalville in Queensland is also known for its black opals, discovered over a century ago. The Jundah-Opalville mine is the site of the largest fine boulder opal ever found, named the Galaxy Boulder Opal, valued at two million USD.
In South Australia, valuable opal fields can be found at Mintabie, Andamooka, and Coober Pedy. Mintabie is known for its fine crystal opals, while Andamooka produces some of the most striking pieces of opal, including light and dark opal. Coober Pedy is a rich source of light and white opal, as well as black opal. The opal fields around Andamooka are quite extensive, covering an area of approximately 45 kilometres.
Queensland is another significant source of opals, particularly boulder opals, which are found in western parts of the state. Yowah and Quilpie are well-known centres of boulder opal mining. The unique Yowah nuts, walnut-sized stones with opals at their centre, are a speciality of Yowah, Queensland. The opal-bearing mines in these regions have attracted tourists, with establishments such as hotels, souvenir shops, and even churches springing up around them.

Australia is the world's largest producer of diamonds by volume
Australia is a leading producer of several precious stones, including sapphires, opals, emeralds, rubies, and diamonds. While it is not true that Australia is the world's largest producer of diamonds by volume — in fact, Russia, Botswana, Canada, and the Democratic Republic of Congo are the top producers — it does lead the world in the production of rare pink diamonds.
The Argyle diamond mine in Western Australia is the source of many of the world's pink and champagne-coloured diamonds. These diamonds are tinted by impurities, which also makes them rarer and more valuable than colourless diamonds.
In addition to diamonds, Australia is also a significant producer of sapphires. The precious blue stone was first discovered in Australia in 1851 in the Cudgegong River by miners who were panning for gold. It was later found in New England, New South Wales, in 1854, and in Central Queensland in 1875.
Opal is another gemstone for which Australia is a notable source. The country's opal mines, particularly those in the states of South Australia and Queensland, are known for their production of valuable black, white, and light opal. The opal fields around Andamooka in South Australia are known for producing some of the most striking opals in the world.

Australia is the only place in the world where Mookite is found
Australia is a treasure trove of precious stones, including diamonds, sapphires, opals, and rubies. However, one stone that is unique to this country is Mookite, also known as Mookaite Jasper. This beautiful and unique gemstone is found exclusively in Western Australia, specifically in the Kennedy Ranges near Mooka Creek, for which it is named.
Mookaite Jasper is a type of chert, opalite, or chalcedony, or a combination of these, with the degree of silica determining its exact description. It is characterised by its bold, earthy beauty and fiery fusion of vibrant reds, yellows, and purples. Mookaite is a sedimentary rock formed from the microscopic remains of tiny radiolarians, a type of protozoa. It is often found as nodules in the Windalia Radiolarite formation, a fossiliferous formation that also contains casts of fossils such as ammonites and belemnites.
The Australian Aborigines considered Mookaite Jasper a stone of Mother Earth, imbued with deep earth energies, and used it as a healing stone to bestow strength and vitality. They believed it promoted an ageless spirit, encouraging a willingness to embrace change and seek new experiences, and helped to awaken one's natural instincts in knowing the right direction to take.
Today, Mookaite is still valued for its metaphysical and healing properties. It is believed to enhance one's connection to the earth and promote a sense of stability and grounding. Mookaite is also thought to encourage self-confidence, boost creativity, and support personal growth, making it a popular stone among crystal healers and energy workers.
Australia's unique geological conditions have created a diverse range of precious stones, and Mookaite Jasper is a remarkable example of the country's natural treasures. With its rich history, cultural significance, and stunning beauty, Mookaite is a sought-after gemstone that continues to fascinate and inspire people worldwide.

Australia is known for producing green jade
Australia is known for its production of jade, specifically the nephrite variety. While jadeite is not found in the country, Australia is a major producer of nephrite, with deposits located mainly in Cowell, South Australia. This deposit is the largest source of nephrite jade in the country, covering an area of about 10 km2 and yielding an estimated 80,000 tonnes of the mineral.
The Cowell deposit is the only commercial jade mine in Australia, with mining operations conducted in open pits using excavators and diamond-tipped core drills. The extracted jade is then transported for grading and further processing, such as cutting and polishing, before being exported to various countries, including Asia, Germany, Italy, the USA, Canada, and New Zealand.
The nephrite jade produced in Australia is known for its deep green colour, making it a valuable and sought-after gemstone. It is often used in jewellery and carvings, similar to jade from other regions like New Zealand, Canada, and the United States. The indigenous Māori people in New Zealand refer to nephrite jade as "pounamu" or "greenstone," and it holds significant cultural and spiritual importance in their traditions.
In addition to the Cowell deposit, Australia has other nephrite jade sources. Minor deposits have been identified near Tamworth, Ogunbil, Spring Creek, Mulla Creek, and Nundle in New South Wales. There are also unconfirmed reports of nephrite jade occurrences in the Pilbara region of Western Australia. These deposits contribute to Australia's reputation as a notable producer of green jade, which is valued both locally and internationally.

Australia is a significant source of sapphires, including the rare parti sapphire
The two main sources of Australian sapphires are New England in northern New South Wales and Anakie in central Queensland. The mines of Australia have produced more blue sapphires than any other source, and these stones are highly valued for their unique colour composition. Australian sapphires are predominantly blue due to the high iron content found on the continent. However, they can also be found in a range of other colours, including yellow, green, and pink.
The parti sapphire, in particular, is characterised by distinct partitions of colour, which can include blues, greens, and yellows. These sapphires are sometimes known as bi-coloured or polychrome sapphires, and their value is on the rise due to their increasing popularity among jewellers. The best gem cutters work carefully to maximise the raw crystal and colour zoning to highlight the unique colours of these sapphires.
The Sapphire is known to represent prosperity, beauty, and inner peace, making it a symbolic and meaningful gift. With their long history and connection to royalty, sapphires have been prized throughout the ages and continue to be sought after for their beauty and rarity. Australian sapphires, in particular, are renowned for their quality and unique appearance, making them a popular choice for jewellery and a valuable asset on the global market.
