16.68ct Natural Unheated Raw Tanzaite Crystal

This stunning unheated raw tanzanite crystal has a gemmy body with a very deep natural color. This crystal has a visually pleasing wedge shape. It weighs 43.29 carats and measures 24.6mm x 17.5mm x 16mm. We do not believe that this crystal has been heated and shows the trichroic colors in the dichroscope.
