Topaz, a gemstone used in jewellery, has been found in Australia since the 1800s. It is usually colourless but can also be blue, orange, brown, green or pink. In Australia, topaz is found in stream gravels and small-scale mining operations or prospecting. The Australian government has set aside 'Designated Fossicking Areas' throughout the country, where people are allowed to hunt for gemstones and gold. Some of the best places to find topaz in Australia include New South Wales, Queensland, Victoria, Western Australia, and Flinders Island in Tasmania.

Topaz is found in New South Wales, specifically in Oban, Mitchell Rivers, and Lightning Ridge
The Mitchell River in Victoria is surrounded by the Mitchell River National Park, where it passes between high cliffs and several gorges. The river is listed as a Heritage River and is of great biological importance as an example of the large-scale biological systems that were once widespread in south-eastern Australia. The river is also culturally significant to the Gunai/Kurnai nation, especially the Brabuwooloong and the Brayakuloong people of central Gippsland.
Lightning Ridge is a mineral locality in Australia known for its high-quality opals, especially the rare black opal. The area has a history of yielding pretty coloured stones, with the first record made in 1873 by Robert Moore, the manager of Muggarie Station (now known as Angledool). In 1880, Aboriginal people brought topaz to the Parkers, the owners of Bangate Station, who suspected the stones were diamonds. Although no diamonds were found, a variety of other attractive stones were discovered in the area.

Queensland is home to the largest topaz deposits near Mount Surprise and Mount Garnet
Queensland is home to the largest topaz deposits in Australia, found near Mount Surprise and Mount Garnet. Topaz was first discovered in Australia as a by-product of metal mining operations. In 1872, tin was discovered in the New England area of New South Wales, and mining soon commenced. When the alluvial material was concentrated, miners sometimes found topaz pebbles. Waterworn topaz was also found alongside gold, tin, and wolfram deposits throughout eastern Australia.
Topaz is a fluoro-silicate of aluminium and is usually colourless, but it can also be white, yellow, light grey, blue, orange, brown, green, or pink. The most common colours of topaz found in Australia are clear, pale yellow, and pale blue. Topaz is often associated with fluorite, cassiterite, and beryl and can be found in dry creek beds and by digging at the top of hills. The crystals are also collected along the track toward the Six-Mile Creek area.
In Queensland, topaz can be found in the Mount Surprise and Mount Garnet areas, as well as in Central Queensland at the Anakie gem fields. The Mount Surprise fields are close to Mount Garnet, and topaz can be found by walking over undisturbed ground and looking for glints of topaz exposed by the elements. Another method is to move a boulder and dig on the uphill side, as topaz is weightier than average creek gravel and can get lodged in backwash crevices during floods.
Since 1968, the Australian government has designated fossicking areas throughout the country, allowing people to hunt for gemstones and gold, usually on private land, as long as they do not interfere with farming activities. These areas include O'Brien's Creek, where topaz can be found in a few days of digging, and Killiecrankie Bay on Flinders Island, where topaz crystals can be found by digging and sieving beach sediments below the high water mark.

Topaz is found in the gem fields of Torrington in New England, NSW
Topaz is a gemstone that usually crystallises in the orthorhombic system and is typically colourless, although it can also be found in blue, orange, brown, green, or pink hues. In Australia, topaz is found in the gem fields of Torrington in New England, NSW. The New England area of New South Wales became a hotspot for mining after the discovery of tin in 1872. As miners worked to concentrate the alluvial material, they often stumbled upon pebbles of topaz.
The gem fields of Torrington, in particular, are known for yielding gem-quality topaz. This topaz is found in the stream gravels (placer deposits) derived from granites. Topaz forms in the late stages of magma cooling when there is a high enough concentration of fluorine to facilitate its formation. It is often found in cavities of igneous rocks like rhyolite, granite, or pegmatite.
In addition to Torrington, topaz can also be found in other parts of New South Wales, including Oban and Mitchell Rivers in the New England area, Lightning Ridge, and Ardlethan. Oban, in particular, is known for producing some of the finest gem material in New South Wales.
Outside of New South Wales, topaz can be found in Queensland, with significant deposits near Mount Surprise and Mount Garnet in the Etheridge Shire. O'Brien's Creek Fossicking Area in Mount Surprise is a popular destination for those hunting for topaz and diamonds. Additionally, there are deposits near Beechworth, Victoria, Coolgardie and Menzies region of Western Australia, and Flinders Island in Tasmania. The topaz from Flinders Island, known locally as the Killiecrankie Diamond, can be found by digging and sieving the beach sediments below the high water mark.

Flinders Island in Tasmania has topaz known as the Killiecrankie Diamond
Topaz is a gemstone that can be found at various sites in Australia. The finest gem material comes from Oban in New South Wales, Mt Surprise in Queensland, and Flinders Island in Tasmania.
Flinders Island, the largest island in the Furneaux Group off Tasmania's coast, is known for its brilliant white topaz, called the Killiecrankie Diamond. The gemstone is found in riverbeds and washed up on the wind-swept shores of Killiecrankie Bay. The name "Killiecrankie Diamond" comes from its brilliance, resemblance to a diamond, and its origin at Killiecrankie Bay. The diamonds can come in hues of blue, pinky-gold, and crystal clear colours.
The Killiecrankie Diamond is said to bring abundance, peace, and joy to the wearer's life. It is also believed to be a talisman that promotes wisdom and connection to the spiritual realm and protects the wearer from illness and accidents.
For those interested in hunting for topaz and diamonds in Australia, the Australian Government has designated fossicking areas throughout the country that permit people to search for gemstones and gold. These areas are mostly on private land, and landholders allow people to hunt for gems as long as they do not interfere with farming activities.
One popular location for topaz hunting is O'Brien's Creek, where quality blue topaz can be found in dry creek beds and by digging at the top of hills. Topaz crystals can also be collected along the track toward the Six-Mile Creek area by simply walking over undisturbed ground and looking for glints of topaz exposed by the elements.

Topaz is found in O'Brien's Creek, also known as the Topaz O'Briens Creek Fossicking Area
Topaz is found in O'Brien's Creek, also known as the Topaz O'Brien's Creek Fossicking Area. The area is located 37km (22 miles) north of Mt. Surprise and just over 400km (248 miles) from Cairns. It is a popular destination for gemstone hunters and fossickers, who can search for topaz and other gemstones in designated fossicking areas set aside by the Australian Government since 1968.
O'Brien's Creek is known for its topaz deposits, and visitors can try their luck at finding these precious stones by digging in the creek beds or along the banks. The inside of curves and bends in the creek are more likely to have topaz deposits as the outside of a bend has faster-flowing water that doesn't tend to deposit solids. When the creek floods during the wet season, topaz is washed downstream, and it may get stuck in backwash crevices or along the bedrock. Visitors are advised to look for areas where the water flow slows down or hits obstacles, as these are prime spots for finding heavy topaz.
One popular method for searching for topaz is by "specking," which involves walking around with your eyes glued to the ground, looking for glints of topaz sitting on the soil surface. Another method is to dig a hole in a likely-looking spot and then use a sieve to separate the topaz from the sand and rocks. Dry sieving may be the only option if water is not available, but rinsing the sieve in water can help make the topaz sparkle and make it easier to identify.
O'Brien's Creek is also known for its smoky quartz crystals, aquamarine, tourmaline, and other gemstones. Visitors can purchase maps of the fossicking area from the campgrounds or the local tourist shop in Mount Surprise, which also offers fossicking tours. It is important to note that most vendors in the area only accept cash, as there is limited access to banks or mobile phone reception.

Frequently asked questions
Topaz can be found in the gem fields of the Torrington, Oban and Mitchell Rivers in the New England area of New South Wales, as well as Lightning Ridge. The finest gem material comes from Oban in New South Wales, Mt Surprise in Queensland and Flinders Island in Tasmania.
Topaz is usually found in stream gravels (placer deposits) derived from granites. It is also found in coarse-grained granites, metamorphic and sedimentary rocks. It is usually colourless but can be blue, orange, brown, green or pink. Topaz is found in the dry creek beds and by digging at the top of hills. You can also collect topaz crystals along the track toward the Six-Mile Creek area.
Dry Sieving is the most frequently used method to separate the topaz from other gravels. A shovel is used to fill a shaker box with gravel from the deposit. Movement of the box separates out the gravels and dust. Then topaz is hand-picked from the remaining larger pebbles.
