This small thumbnail specimen consists of a crystalline mass of carnallite. While crystal faces are plentiful on this specimen, it is a partial crystal-its orthorhombic form cannot be ascertained. It is colorless and transparent, with a vitreous to greasy luster. It is fluorescent dark purple in short wave ultraviolet light, but does not show the phosphorescence this species is sometimes noted for.
