The Black Opal from Lightning Ridge is exceptionally rare, however when a "Pattern" is present the Gemstone moves into a category that represents 1% of all Gem Black Opals. Patterns such as "Harlequin", "Moss", "Chaff" and "Peacock" are just a few. Every single Black Opal Pendant comes with an international Guarantee and Warranty. This is quite possibly the rarest, and most valuable commercially available gemstone on Earth!
