The Tanzanite

Tanzanite, the rival of Sapphire ....

Rare gemstone, very rare to see, since we only know a single deposit in the world, Tanzania is about to dethrone his rival sapphire.

The only known mine in the world is located in Tanzania at the foot of Kilimanjaro, near Arusha.

Thousand times rarer than diamonds, Tanzanite fascinated by its purplish blue hues and brightness unusual.

Tanzanite is the blue-violet variety of a mineral called zoisite, discovered for the first time in 1969. It was quickly named "Tanzanite" from his country of birth by Tiffany & Co. from New York who introduced it in the United States. The success was immediate!

His blue-violet often have a depth comparable to the finest sapphires.

The most popular Tanzanite on the market is that of a very bright blue or blue-violet very intense lavender.

Without human intervention, tanzanite has brown hues. It is common and accepted that most Tanzanites are heated.

Tanzanite has a hardness of 6.5 / 7 on the Mohs scale.

Due to a very important cleavage, this stone is fragile, so a rise in tanzanite ring must be worn with great care.

But do not forget, all the stones are fragile! even the diamond ....
