ABOUT BLACK OPALS
Found only in Australia, mainly at Lightning Ridge in outback New South Wales, black opal is the world's rarest and most valuable type of opal. Ablaze with a rich and vibrant rainbow of colour set against a dark or black body tone, black opal is highly prized for its intense spectrum and features in the world's finest jewellery collections. If an opal's body tone is dark but not truly black, it is known as dark opal. Read more about Australian opals.
