Dravite Tourmalines may not be the most beautiful on earth, with their dark coffee colour and usual lack of transparency (particularly as they get larger), but they are one of the more uncommon Tourmaline varietals. And this is a BIG one, an old-timer from Australia. It has fine sharp faces and good luster. It is a superb floater, nearly complete all around with only minor imperfection. This whopper weighs 188 grams.
