Small cabinet. Three major crystals dominate the top of this matrix plate of hausmannite, smothered by a soft carpet of oyelite. The two frontal crystals are 4 cm long, and a 5 cm crystal runs under them, linking them all together in a chain of color. A larger, thicker, broken-off crystal is a backstop at the base of the cluster.
