A large crystal of fancy zoisite basically tanzanite in different colors has a nice form and an unusual bicolor patterning. Its core is dark purple tanzanite while most of the crystal is yellow or greenish yellow. This is large sized for a fancy zoisite which is much rarer than purple tanzanite. This piece is gemmy and well formed. A previous owner has polished the two chisel crystal faces of the termination, and I have discounted this piece heavily for that reason.
