Violetish Blue Tanzanite · 4.38 ct
Tanzania · 4.38 ct
The mineral was called blue zoisite when it came out of the ground in 1967. Tiffany renamed it after the country a year later, on the reasonable view that nobody would wear something that sounded like that. Cut near-square and deep, so neither the violet nor the blue takes charge of the stone.
