AF837 - Chrome Tourmaline sold
Landani, Tanzania

Superb gem quality crystal. Known as \"Chrome\" Tourmaline, it is actually a vanadium rich Uvite/Dravite. These are uncommon to find and this is of excellent quality, though dark green, backlighting reveals the high transparency, like green glass, 53 carats in weight.
AF841 - Sphalerite with Pyrite and Calcite (?) sold
Merelani Hills, Lelatema Mtns., Arusha Region, Tanzania
Thumbnail - 1.8 x 1.7 x 1.6 cm
Translucent red Sphalerite crystal, only the second Sphalerite I have seen from Merelani. The top of the crystal is partially coated by Pyrite, atop which are what I beleive to be Calcite crystals which have an unusual \"wheatsheaf\" habit. This would be a nice addition to a Merelani suite.
