Complete single Alabandite crystal from the Merelani Tanzanite mines in Tanzania. This is a high quality, complete crystal with smooth faces and all 6 tips present. There is a natural pit on one side where the crystal formed around a knob of Graphite and there is some Graphite remaining, along with small Diopside crystals. Merelani Alabandite are considered the world's best and largest examples of the species. A very nice example from the Tim Sherburn collection.
