Topaz is a gemstone that comes in a variety of colours, including clear, pale yellow, and pale blue. In Australia, topaz is typically found in stream gravels (placer deposits) derived from granites, and most Australian topaz is found in alluvial placer deposits. Gem-quality 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. Topaz has also been found in Queensland, with the largest deposits occurring near Mount Surprise and Mount Garnet. There are also designated fossicking areas throughout Australia that permit people to search for gemstones and gold, such as the O'Briens Creek Fossicking Area near Mount Surprise.

Topaz in New South Wales
Topaz is a gemstone that occurs in a variety of colours, including clear, pale yellow, and pale blue. It is often found in alluvial placer deposits and is known to be associated with minerals like fluorite, cassiterite, and beryl. In New South Wales, Australia, topaz can be found in several locations. Here are some specific places where you can hunt for topaz in this state:
Oban, New South Wales
Oban, located in the New England area of New South Wales, is known for yielding some of the finest gem-quality topaz in Australia. The Oban River has produced significant quantities of topaz crystals, which are often water-worn and range in colour from colourless to pale blue. The topaz found in Oban is highly regarded for its clarity and has been used to create large, faceted gemstones.
Mitchell River, New England Area
The Mitchell River, also situated in the New England area of New South Wales, is another notable source of gem-quality topaz. Similar to Oban, this river has yielded fine topaz crystals, cleavage fragments, and pebbles. The topaz found here is also known for its clarity and has been used in jewellery making.
Torrington Gem Fields
The Torrington area in New South Wales is recognised for its gem fields that produce topaz. These fields are located in the New England region and are a significant source of topaz gemstones. The Torrington area is also mentioned as a site for deposits of industrial-grade topaz, which are found in quartz-rich rocks (silexite).
Lightning Ridge
Lightning Ridge in New South Wales is another location where topaz can be found. While it is not as widely known as the previously mentioned sites, Lightning Ridge has been identified as a source of gem-quality topaz in the state.
Broken Hill and Ardlethan
Primary topaz deposits can be found in Broken Hill, New South Wales. Here, topaz occurs in metamorphic rocks, giving rise to topaz crystals. Additionally, Ardlethan in New South Wales is known for its granite deposits, which also contain topaz.
When searching for topaz in New South Wales, it is important to be aware of designated fossicking areas set aside by the Australian government. These areas, like the Designated Fossicking Area (DFA) near O'Brien's Creek, allow people to search for gemstones legally. Dry sieving in creek beds can also yield topaz crystals, especially after rain has scoured the creek banks.

Queensland's topaz deposits
Queensland is home to some of the largest topaz deposits in Australia. The state's topaz deposits are primarily found in the Mount Surprise and Mount Garnet areas, with notable deposits also located in the O'Briens Creek Fossicking Area, in the Etheridge Shire.
The Mount Surprise deposits are located in North Queensland, about 400km from Cairns. This area is known for yielding high-quality topaz gemstones, with the nearby O'Brien's Creek fossicking site being a popular destination for gem hunters. The site is easily accessible and offers the opportunity to find topaz, along with other crystals such as smoky quartz and aquamarine.
The O'Briens Creek Fossicking Area is a designated area for gemstone hunting, located about 37km north of Mount Surprise. This area is particularly popular for surface fossicking, which involves searching for gemstones on the surface without the need for digging or mining. The site is known for its abundance of topaz, smoky quartz, and aquamarine crystals.
In addition to these sites, Queensland also offers other topaz deposits in Central Queensland, such as the Anakie gem fields. While these sites may not yield gemstones as frequently as the more popular areas, they still offer the thrill of the hunt and the chance to discover unique pieces.
Overall, Queensland's topaz deposits provide a range of opportunities for gemstone enthusiasts, from casual family outings to more dedicated hunting expeditions. With its diverse locations and the potential for significant finds, Queensland is a key destination for those seeking to uncover the beauty of topaz in Australia.

Victoria's topaz sites
Victoria is home to several topaz sites, with the gemstone found in the state's rivers and creeks. One notable location is Big River in Glen Valley, East Gippsland Shire. The river is known for yielding water-worn topaz crystals, which can be found by carefully searching through the riverbeds and along the riverbanks.
Another topaz site in Victoria is the Mitchell River in the New England area. The river has produced fine topaz crystals, fragments, and pebbles that have been used to create large, clear gemstones. The Mitchell River is known for its gem-quality finds, attracting those eager to uncover the shiny stones.
For those seeking a more adventurous topaz hunting experience, Victoria offers the Blue Hills and McDonald Creek fields. Accessible by a four-wheel drive, these sites have been less frequented due to the challenging terrain. However, quality blue topaz can be found in the dry creek beds and by digging at the top of the hills. The weight of topaz, which is heavier than average creek gravel, makes it more likely to be found in these areas.
In addition to the sites mentioned above, Victoria likely has other topaz-bearing locations yet to be discovered or popularized. Designated Fossicking Areas (DFA) set aside by the Australian Government may offer further opportunities for topaz hunting on private land, as long as visitors respect farming activities.

Western Australia's topaz
Topaz crystals, which are usually colourless to pale blue, can be found at various sites in Western Australia. One of the most popular sites for topaz hunting is O'Brien's Creek, located 37km north of Mt Surprise and 400km from Cairns. The area is accessible by conventional vehicles and offers the opportunity to fossick for topaz, quartz crystals, and other gemstones in the sandy creek beds.
Another well-known location for topaz hunting in Western Australia is the Mt Gibson topaz fields. This site has been a popular destination for families and gemstone enthusiasts for decades. While it may require a more rugged mode of transportation to reach the fields, many have found the journey rewarding in their search for topaz.
In addition to these sites, Western Australia also offers Designated Fossicking Areas (DFAs) where people can search for gemstones. These areas are often on private land, and visitors are advised to respect the farming activities that take place there. One such DFA is the Emerald Pool mine in Poona, Cue Shire, which is known for yielding various gemstones, including topaz.
The finest gem-quality topaz in Australia is said to come from Oban in New South Wales, Mt Surprise in Queensland, and Flinders Island in Tasmania. While these sites are outside of Western Australia, they contribute to the country's reputation for yielding high-quality topaz gemstones.

Tasmania's Killiecrankie Diamond
The Killiecrankie Diamond, also known as the Tasmanian Topaz, is a form of brilliant white topaz found only on Flinders Island in the Bass Strait. Flinders Island is the largest island in the Furneaux Group off Tasmania's coast. The Killiecrankie Diamond is not a real diamond, but its name has been used for many years due to its brilliance.

The Killiecrankie Diamond is found in Killiecrankie Bay on Flinders Island. The island is known for its wild and untamed beauty, and the diamond is said to hold a unique place in the hearts of those who visit. The founders of Claudia Jewellers, Scott and Freya, met and fell in love on Flinders Island over 23 years ago, and they continue to draw inspiration from the elusive water-worn pebbles of the Tasmanian topaz for their Furneaux Collection.
The Killiecrankie Diamond is considered a special gemstone with mythical properties. Legend says that it has the power to protect its wearer from illness and unfortunate accidents. It is also fabled to be a talisman that promotes wisdom and connection to the spiritual realm.
