Rare, spectacular, and utterly unlike anything else.

Tanzanite — Found Only Once, in One Place, in the History of the Earth
Tanzanite was discovered in 1967 by a Maasai tribesman named Ali Juuyawatu, who found brilliant blue crystals glittering in the sun near the village of Merelani in northern Tanzania. Within two years, Tiffany & Co. had acquired distribution rights and named it tanzanite after its country of origin — and declared it the most significant gemstone discovery in two thousand years. Its extraordinary quality is trichroism: viewed from different angles, tanzanite shows deep sapphire blue, vivid violet, and a warm burgundy — three completely different colors in a single stone, depending entirely on where the light falls. Geologists estimate that tanzanite is a thousand times rarer than diamond and that the existing deposits will be exhausted within decades. To wear tanzanite is to wear a piece of geological history that cannot be replaced.
A magnificently rare and beautiful gift for those who appreciate genuinely extraordinary things, for December birthdays, and for anyone who deserves jewelry as rare and irreplaceable as they are.
