Thin Conichalcite crusts partly cover the surface of this larger cabinet specimen. These crusts show no evidence of crystal form and have the grass-green color that is standard for this specie. The Conichalcite has a dull, matte luster and is opaque, and is partly covered by layers of a colorless mineral that may be calcite or smithsonite. The base rock on which it rests has some iron-oxide staining, but appears to consist primarily of calcite or another calcium mineral.
