This is a cluster of crystals of the "other" brown tourmaline, buergerite. While it is considered difficult to distinquish from dravite, this specimen looks quite different than most dravites. It has a pattern of gold highlights that give it an interesting surface luster, very nice. Also, several of the crystals are excellent (although all are small), having good form and even being doubly terminated.
