Green “Tanzanite” crystal from Pakistan. These have always been intriguing to me as only the second locality I’m aware of that produces gem quality Zoisite, however production was always very sporadic and nothing has been turning up for years. I bought this about 15 years ago and it has been in my collection ever since. The left side of the crystal has some gemmy zones with great green coloration. Complete all around.
