"Dreaming Opals"

The Koroit opal field is an opal mining area in Paroo Shire in South West Queensland, Australia. It is located about 80 km north northwest of Cunnamulla. It is not a town, nor should it be confused with the town of Koroit in rural western Victoria, Australia. It has neither electricity nor running water. Koroit is close to the town of Yowah which also produces a similar type of opal.

The Koroit opal field is known for the very distinctive type of boulder opal that is found in its mines. In Queensland boulder opal is found within a 300 km wide belt of sedimentary rocks in the Winton Formation. Here opal is found as a kernel in small concretions.

The Koroit Opal field was discovered in 1897 by Lawrence Rostron. The most recent mining events started in 1972 when the popularity and profitability of the stone increased. The mining is done by either open cut large scale mining or by underground shafts.

 

Stone :  Koroit Boulder Opal

Outback Queensland Australia

Cut and Polished. 

This beauty is ready to be set in jewellery. 

Natural and Untreated. (There is a lot of times that cutters use a epoxy to fill the natural holes in the stones which when you hold the stone in your hand it you get a plastic feeling. This has become a common practise)

Good pattern and colour

We use a 100mm Macro Lens to capture as much detail as possible, sometimes these details are not visible to the common eye.

Please note : Not all scales are made the same, so slight variation in measurements and weight are to be expected.

Also with finished stones we generally take thickness measurement in the middle of the stone.

Specializing in Queensland Boulder Opal, all fields. We source our rough directly from miners and miners only on majority of our stock. I had left the business for a few years to follow another career path, this did not last long and back in the game full time. Concentrating mostly on rough and rubs from Yowah, Koroit and some traditional boulder from Winton, Quilpie, Jundah, Eromanga and Opalton. Working hard to bring you the best prices and quality. As time progresses so will my stock level.
