This specimen consists of several prismatic crystals of dyscrasite on a black matrix of what I believe to be silver sulfides. The largest dyscrasite crystal measures 0.3" (0.8cm) in length. The end of the specimen reveals a dyscrasite crystal wrapped in concentric layers of the black matrix material. This may indicate that the black material might be an alteration product of the dyscrasite. All of the dyscrasite crystals show varying degrees of damage; there are no termination faces present. This specimen is affixed to a small plastic box for protection.
