TURQUOISE: The Historic Opaque Mineral

TURQUOISE: The Historic Opaque Mineral

One of the three “Birthstone of December” is Turquoise. As water moves through porous rock, minerals are dissolved, such as copper, aluminium and iron. Over a long time, these minerals accumulate in pores and cracks to form deposits of the material we know as Turquoise. The colour of the stone varies depending on the amount of iron and copper present.

The name “Turquoise” is said to derive from “Turkish”, because the trade route that brought it to Europe first time came via Turkey.  Most of the world’s turquoise rough is currently produced in the southwestern United States, China, Chile, Egypt, Iran, and Mexico. Arizona, New Mexico, and Nevada have all held the position of the leading turquoise-producing states in USA.
