描述
Tanzanite
Tanzanite is the blue and violet variety of the mineral zoisite (a calcium aluminium hydroxyl sorosilicate), caused by small amounts of vanadium.[3] Tanzanite belongs to the epidote mineral group. Tanzanite is only found in Tanzania, in a very small mining area (approximately 7 km (4.3 mi) long and 2 km (1.2 mi) wide)[4] near the Mererani [sw] Hills.[5]
Tanzanite is noted for its remarkably strong trichroism, appearing alternately blue, violet and burgundy depending on crystal orientation.[6] Tanzanite can also appear differently when viewed under different lighting conditions. The blues appear more evident when subjected to fluorescent light and the violet hues can be seen readily when viewed under incandescent illumination. In its rough state tanzanite is colored a reddish brown to clear, and it requires heat treatment to remove the brownish "veil" and bring out the blue violet of the stone.[7]

積極的I love the cut, clarity, and incredible teal color of this sapphire. The AIG certificate is a great bonus, shipping was quick, and the stone looks very high quality. I’m thrilled with my purchase and will be watching for more listings from this seller.

Invoice paid on Oct. 25. Paid for "DHL 10 day delivery." 17 days later package never shipped. Package finally arrived on 11/14. Significant issues with poor communications. Stone is beautiful!
