Gem, Rock, and Mineral Postage Stamps Featuring
Turquoise


Mineral Name: Turquoise
Composition: Hydrous copper aluminum hydroxyl phosphate
Nomenclature: Named after the word Turkish in the mistaken belief that material obtained via trade routes through Turkey actually originated in Turkey.
Industrial Uses: Jewelry; minor ore of copper.
Additional Notes: A member of the Turquoise group of minerals. In older mineralogy texts, the name of this mineral was spelled turquois. This spelling persisted into the mid-1960s. Turquoise crystals are rare. For many years, the only known occurrence of turquoise crystals was the Bishop Mine, Lynch Station, Campbell County, Virginia, a site which is now flooded. In the last few decades of the 20th century, a small number of additional worldwide locations of turquoise crystals have been documented.
