    Turquoise is an opaque, blue-to-green mineral that is a hydrated phosphate of copper and aluminum. It is rare and valuable in finer grades and has been prized as a gemstone and ornamental stone for thousands of years owing to its unique hue. In recent times, Turquoise has been devalued, like most other opaque gems, by the introduction onto the market of treatments, imitations and synthetics
