ABOUT BLACK OPALS: Over 100 years ago in 1915, a small group of men named the New Colorado Prospecting Syndicate were searching for gold in Australia but found opal instead. The opal from 12 Mile Opal Field, Coober Pedy, South Australia is a true precious stone but only 10% of the stones that are mined, are vividly colored like the black opals we use in our jewelry.
