Glassy yellow Zoisite crystal (yllow Tanzanite) with an unusual 'blue hole' at the base. This is a really odd one - in the base, where the yellow is more translucent, there is a transparent blue zone, somewhat circular in shape, that crosses horizontally through the crystal. This blue zone is not visible from two of the faces, but from the other two faces, you can look straight through the crystal - the visual effect is more striking in person. Natural, complete, unheated gem crystal. Weighs 14.12 carats.
