There is a well-appointed bowling club with its eight artificial-grass bowling greens. Temperatures in summer can reach into the high 40s Celsius, but below ground the temperature remains continually at around 22 degrees, year round. The Lightning Ridge area is a world-renowned centre of the mining of black opals and other opal gemstones. Lightning Ridge has the largest known deposits of black opals in the world.
The name Lightning Ridge is said to have originated when in the 1870s some passers by found the bodies of a farmer, his dog and 200 sheep which had been struck by lightning. Absolute Opals is a second generation mining enterprise, Here are some pictures of our mining activity. We prospect for opal with a 9 auger drill. When good material is discovered we drill a shaft down to reach the opal level.
When payable material is found, we put a mechanical digger down the hole. The dirt is removed by a blower kind of like a giant vacuum cleaner.When the truck is full, it goes to the Agitator, a modified cement mixer where it is washed during the week. Up to 10 truckloads of dirt go into each batch of wash, which accumulates and wears down to concentrate by the end of the week. Then, we just pick out the gems, often none, but once every few years you drop onto a pocket.
Then it is off to the cutting 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.

The human eye sees things slightly differently to the digital camera because of the different mechanisms of how they register light. Each persons eyes see a little differently to the next persons eyes.
Many computer screens are manufactured and calibrated a little differently to each other. Example; a LED screen will have alot more contrast than a Laptop Screen. The opal colours and patterns seen are a result of a complex combination of refraction, diffraction, diffusion and reflection of light from the opal structure. When an opal is viewed with different light sources and different light intensities the effect of the stone can change a little from one light source to the other.
The total combination of these facts means there will be some degree of inaccuracy when representing opal with digital photography. To compensate for these factors I like to list items with still photos and a movie with all care and techniques taken to represent the stone as accurately as possible.
