Brown to purplish brown, lustrous, tabular crystals to 7mm. This is a great Axinite specimen with superb crystals. The original label with the specimen places the locality as Mt. Bischoff. I believe it is actually Colebrook based upon crystal forms and the association with Danburite, which are white to faint green crystals on the Axinite.
