Turquoise
Turquoise is an opaque, blue to blue-green phosphate mineral that has been valued as a gemstone for thousands of years. The colour results from the presence of copper, while iron sometimes causes a greener hue. Turquoise often occurs with dark matrix lines of surrounding rock, giving it a distinctive appearance. The stone was named after the Turkish trade routes through which it was introduced to Europe.
Major deposits of turquoise are Iran, the United States (especially Arizona and Nevada), China and Egypt. The mineral forms in dry, desert areas as a secondary mineral in the oxidation zones of copper deposits. Its chemical formula is CuAl₆(PO₄)₄(OH)₈-4H₂O. Turquoise has a hardness of 5 to 6 on the Mohs scale.
