Lightning Ridge Natural Black Opal
By Faye Kim
Located in Darien, CT
Spectacular in color and shape and exhibiting a stunning range of colors, this 2.80 carat natural black opal is a gem-quality stone for the avid collector or jewelry lover.
Unlike ordinary opals, black opals have carbon and iron oxide trace elements present, which cause the unusual darkness of the stone. Because of their dark body tone, the rainbow colors in a black opal truly stand out.
The stone's mesmerizing blue, green and golden hues render it ideal for creating a truly one of a kind statement ring, bracelet, necklace, or pendant. Let us help you design your own signature piece. For inspiration, see some of the opal pieces Faye Kim has created in the attached photos. The designer will work with you to create your own spectacular, one-of-a-kind piece using this Lightning Ridge...
