This gem was faceted from an unheated piece of tanzanite–most tanzanite has been heated to remove the orange-brown and greenish-yellow components and to turn the gem to a dark blue to purple-blue color. We prefer the natural mixed colors and pastel tones of unheated Tanzanite (sometimes called “Fancy Tanzanite” or “Fancy Zoisite”). Tanzanite is the trade name for deep blue to blue-purple Zoisite that is found in only one location on the earth–the hills of Merelani, Tanzania. However, this particular gem was cut to show a very rare shade of yellow. This Tanzanite is nearly flawless; there appears to be no visible inclusions, even when examined with a 10x loupe.
This Tanzanite is faceted in our custom “Stella” brilliant square cushion design. The gemstone weighs 1.81 carats and measures 7.3 x 7.3 x 5.0 mm.
