7.5" Tanzanite Chip Bracelet (1pc) NETT

Tanzanite is the rare blue/purple variety of the mineral zoisite which was discovered in Northern Tanzania in 1967. Tanzanite is noted for its remarkably strong trichroism, appearing alternately sapphire blue, violet, and burgundy depending on crystal orientation. Tanzanite in its rough state is usually a reddish brown colour. It requires artificial heat treatment to 600 ﾰC in a gemological oven to bring out the blue violet of the stone.
