What Gemstone is Black Opal?

Australian black opals are the most valuable and widely known type of opal. Black opal is characterised by a dark body tone which can range from dark grey to jet black.


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 orange fire that can also come in other colours of the rainbow,  stand out much better in a black opal  than lighter opals.
