these blue-tipped tourmalines were only found once in a large pocket at Mwajanga. Most of these crystals are black to dark green, the upper part is colorless to slightly greenish in color, also partially transparent, and then follows a blue zone of varying intensity. Matrix levels were very rare, otherwise only loose crystals, the exceptions are double ended.
