About Tanzanite

Since a Masai tribesman stumbled upon a shimmering blue crystal in the foothills of Tanzania's Mount Kilimanjaro in 1967, tanzanite has become one of the world's most cherished and sought-after gemstones. Named for its country of origin, Tanzania, and its stone type, zoisite, Tanzanites are blue, ranging in shades from exquisite royal blue to lilac and periwinkle. With the supply of the gemstone likely to last just a single generation, tanzanite has captured the imagination of the world's most beautiful people, and earned its rightful place next to diamonds as a must-have gemstone.

Zoïsite (Tanzanite)

Spawned during the Pan-African Event, when massive geological activity ripped Africa from India and set Asia adrift from North America, tanzanite’s geology is so unique that it has been described as a geological phenomenon.

While zoisite itself occurs widely, the random presence of vanadium in the same vicinity under exacting geological conditions more than 585 million years ago created the ideal environment for tanzanite’s conception. Tanzanite’s formation is so rare that it has been described as being ‘more astounding than the stone itself’. Experts maintain that the chance of tanzanite occurring elsewhere in the world is one in a million.

Tanzanite is trichroic, which means that in its rough form it radiates three different colors from each of its crystallographic axes, namely blue, violet and burgundy. Once cut and polished, the stone becomes a kaleidoscope of royal blue, violet, indigo, lilac and periwinkle shades. While the different hues appeal to different tastes, the most distinctive and desirable shade is vibrant violet blue.
