Violet-Blue Tanzanite · 6.59 ct
Tanzania · 6.59 ct
Every tanzanite ever sold came out of the same few square kilometres of hill in northern Tanzania. There is no second deposit and there has never been one. Cut long, and it holds the calm mirrored depth that suits it, with the violet and the blue reading clean down the length.
