This is a unusual  natural stone showing strong green colour.I was at a dealers shop in Tanzania and he had this one piece of unusual rough that he wasnt sure where it came from.So it could be from Tanzania or Kenya. Our gemmologist tested it and the refractive index is 4.5 and confirmed it as opal-great piece for any collection.
