Blue Diamond mine is in Nevada, near Austin. It produces turquoise often with a black chert matrix.
Turquoise is a semi-precious mineral composed of hydrated copper and aluminum phosphate. It’s name comes from the Turkish traders who brought it from Persia to Europe, hence the French “turquois”. Water flowing over rock released minerals that flowed into crevices and formed veins and nuggets of turquoise. Other minerals are often present, in fact the composition varies with location. Turquoise is often formed as veins in a host rock.
