Perched on one corner of this host rock are several crystals of buergerite. They are brown and opaque, except for golden highlights that reflect from a bright light. The crystals (while small) are large enough to see the hexagonal structure and lengthwise striations typical of tourmalines (a family in which buegerite belongs). A loupe reveals excellent crystals with golden highlights reflecting from internal fractures, making this prettier than any dravite specimen that I have seen. The largest crystal measures 4 or 5 mm long.
