Though it is very difficult to see under white light, this cabinet specimen contains a sizable amount of Willemite. When exposed to shortwave UV light, the classic bright-green fluorescent color of the Willemite is very easy to see. It appears to show no crystal form, and its dark brown color blends in with the dark color of the biotite mica that covers most of the piece. A substantial amount of massive, white calcite is also present- it exhibits a rather bright orange fluorescent color under UV.
