We, at Absolute Opals & Gems (Australia), are second generation Opal Miners, Gem Cutters and Wholesalers, proudly specialising in Australian Black Opal, directly from the mines.
You will find us located in the heart of the busy mining town of Lightning Ridge New South Wales , approx. 750 km or 468 miles, north west of Sydney, Australia.

Here are some images of our mining activity:
Prospecting drill shown here
We prospect for opal with a 9 inch auger drill. When promising material is discovered we drill a 3 foot diameter shaft down to a depth that bottoms on the opal bearing level.
When, what appears to be payable material is found, we lower a mechanical digger down the shaft.
Underground digger shown here.
The dirt is extracted by a “blower” which in reality is more akin to a giant vacuum cleaner.
Truck and blower shown here;
When the truck is full, it is taken to the “agitator”- a modified cement mixer- where the extracted dirt is washed for the duration of the mining week. Up to 10 truckloads of dirt go into each batch of wash, which wears down and accumulates into a concentrate by the end of the week.
Agies shown here.
Then, we just manually sort through the washed clean concentrate called “tailings”, to pick out the gems, often none, but once every few years hard work is rewarded by discovering a pocket of truly beautiful gems!
Rough opal shown here.
Then it is off to the cutting and polishing room.

Many people come to Lightning Ridge for weeks at a time on holiday to fossick through the dumped material where valuable opals are sometimes missed by the miners.
Fossicking for overlooked opal on abandoned mining claims is a popular activity. If you are lucky, and work hard at it, there is every chance you will find valuable opal.
Lightning Ridge is an important paleontological site, with fossils dating back to the Cretaceous period, 110 million years ago. The sandstone rock once formed the bottom of a shallow inland sea where the remains of aquatic plants and animals were preserved. The site is especially important as a source of fossils of ancient mammals which, at that time, were small creatures living in a world dominated by dinosaurs. The fossils are sometimes opalised and discovered by opal miners. Important discoveries at Lightning Ridge include the ancestral monotremes Kollikodon ritchiei and Steropodon galmani.
Plentiful crops of wheat are grown in the dry lakes surrounding the opal bearing ridges.
After a long day, you can relax in the artesian thermal pool- it is free!
