This is a stunning bi-colored unheated tanzanite necklace. The setting and chain are both made from solid 14k white gold.

Almost all tanzanite available on the market today has been heated to give it is blue color. Which makes unheated tanzanite super rare.

(The photos were taken outside, inside this item appears slightly darker and there is less color distinction, it appears more purple blue inside instead of the clear two colors when outside. I am happy to provide more photos if you wish to see before purchasing)
