Most of the mass of this thumbnail specimen consists of Purpurite, though there is a small amount of brown host rock present. The purpurite does not appear to have a definable crystal form, and is thus in essentially good condition. It does show the classic violet coloration with a hint of red and the almost silky luster that is a common characteristic of the species. It is opaque and has a slightly powdery consistency- it will rub off a little when the piece is abraded slightly. The surrounding brown host rock is also a bit chalky, which make me think that it is made of limonite.
