This gorgeous unheated raw tanzanite crystal has a dark brownish base in the lower half which splits into the beautiful natural violet color towards the termination. This crystal has a very pleasing shape that would work great as a (larger) pendant if you were to make it into a piece of jewelry. It weighs 34.73 carats and measures 36.4mm x 11.6mm x 10mm. We do not believe that this crystal has been heated and shows the trichroic colors in the dichroscope.
