GTR-254-21   6.63 ct. AAA+ Natural D' Block Trillion Tanzanite IGI Certified! Price: Call for Price

Kashmir cornflower blue of the highest intensity. This beautiful investment grade piece closely resembles a Kashmir sapphire due to its dreamy, velvety blue hue.
The resemblance ends though when seen under incandescent light as a riot of red flashes explodes within the stone.
This wonderful 6.63 carat AAA+ Tanzanite is extremely rare; its color harks back to the early days of Tanzanite mining and is very rarely mined these days.
Flawless and top cutting.
A superb investment grade piece in all respects.

TANZANITE Tanzanite is an extraordinary gemstone. It occurs in only one place worldwide. Its blue, surrounded by a fine hint of purple, is a wonderful color. Tanzanite is a blue variety of the gemstone Zoisite. It consists of calcium aluminum silicate and is not particularly hard, having a value of 6.5 to 7 on the Mohs scale. For that reason, it should always be worn carefully and never placed in an ultrasonic bath for cleaning or brought into contact with acids. Tanzanite is the blue/purple variety of the mineral zoisite discovered in the Meralani  Hills of northern Tanzania in 1967, near the city of Arusha. However most tanzanite is subjected to artificial heat treatment to improve its color
