One of the larger specimens that I have seen of this material, this piece is made up almost entirely of a titanian Andradite garnet that is called Melanite. The crystals are not completely individual, as they are heavily packed together and only a few faces of each crystal are visible. They have a black color with hints of brown, a pearly-to-vitreous luster, and are opaque. The crystals occur in the dodecahedral form, with visible growth patterns on their faces and very thin secondary faces truncating each edge. Though the only large crystals are those on the natural surface of the specimen, there are several layers of smaller, intergrown garnets that are visible under the main layer. They are more brown in coloration and are heavily damaged, as they are at the place where the specimen was broken off of its place of origin.
