Something that we can quite honestly say we have never had before - a faceted example of the manganese oxide known as Psilomelane. There are few minerals in this group and it is not rare material, but we certainly have never seen a cut stone before. As you would expect, it is opaque with a metallic luster, but the most interesting part is the visible growth structure of the species - the classically botryoidal habit is easily seen across the entirety of the stone. Fascinating piece, collected in New Mexico.
