20.70ct Celestial Towering Tanzanite Crystal

This beautiful lightly color violet blue tanzanite cluster has a very celestial look  to it. It weighs 20.70 carats and measures 33.5mm x 14.5mm x 7.6mm. This piece us very unique with the two attached crystals standing vertical, and the other angling partially horizontal to the first two. We believe that this crystals color has been enhanced by heating.
