This flat cabinet specimen is made mostly of massive, white Calcite. The Calcite shows no definite crystal form and actually has a creamy coloration. It serves as the matrix for several spots of willemite and one straight vein that runs completely through the piece. The willemite does appear to be crystalline to a degree and has a color that ranges from a reddish-brown to a pale, rusty orange. When bathed under shortwave UV light, however, the calcite glows a slightly dim, orange color and the willemite glows bright green. When the UV light is suddenly switched off, the willemite phosphoresces - this means that the willemite continues to glow green for a while after the UV radiation is removed.
