Art Nouveau Black Opal Diamond Enameled Ring

Black opals are the most rare and valuable of all natural opal varieties. These amazing stones exhibit amazing color backed by dark or black "potch", or common opal, unlike their white opal counterparts, which are backed by more common white potch. The dark base tone gives striking contrast to the brilliant rainbow of colors and patterns, which come about as a result of variations in the orientation and size of microscopic beads of silica within the stone. Although a small portion of the world's opals are mined in Ethiopa, Mexico, and Brazil, black opal specifically is exclusively mined in Australia (particularly from a region known as "Lightning Ridge") and the opal has henceforth been named Australia's national stone. Historically, opals were believed to bring good luck when given as a gift. In the modern day, they continue to be adored worldwide and are one of the most desirable stones used in fine jewelry!
