Overview: Villiaumite derived its name from the French explorer Villiaume. It has a typically bold red "carmine" color that is visually unique. Although its carmine-red color can be very attractive, it is very soft, cleaves easily, and is somewhat water soluble.
Villiaumite can be distinguished from other minerals by its crystal habit and color. It is commonly found associated with Amphiboles, Calcite, Eudialyte, Fluorite, Nepheline, Pectolite and numerous other minerals from sodalite xenolith environments.
Usage: Rarely cut as gemstones and collected
as mineral specimens.
Villiaumite was described by Lacroix
in 1908, and named after a French explorer who collected
Occurrence: Rouma, the Islands of Los, Guinea, Khibina Massif, Kola Peninsula, Russia; Aris, Namibia; Colfax County, New Mexico, USA, Mont Saint-Hilaire, Quebec, Canada and Greenland.
Villiaumite is a sodium salt and those salts are usually soluble. A desicant should be placed with any specimen to avoid moisture absorbtion and thus its possible destruction.
