- Ex. Charlie Key
The Otjua Mine in Namibia is known for its polychrome Tourmaline, but finding crystals or even slices like this is difficult. This is a showy bicolor Elbaite Tourmaline slice displaying a raspberry red core with a medium green core area and has a great polish on both sides. The slice is 2mm thick. Beautiful!
