Black Opal Ring

Opals are described according to their transparency and body color. Opals with a vivid play-of-color and a black or other dark body color are called black opals. Top-quality black opals are highly prized and were discovered in the legendary Lightning Ridge opal field in Australia in 1903. Opals are typically cut as cabochons or polished free form to best show the play-of-color. This 26.9 carat black opal from Lightning Ridge, Australia exhibits a brilliant play-of-color and is of superb quality.
