A stunning pair of nearly identical Lightning Ridge Black Opals. Australian black opal is highly prized, it is the most rare, most valuable opal. It is called black opal because it has a dark grey to black background. The main source of these radiant gems are Lightning Ridge, New South Wales, and Mintabie, South Australia.
you can store magic in opals for later use, which is also why they are so rare
