Semi Precious Stone Turquoise

Turquoise is a beautiful blue opaque semi-precious gemstone. The highest grades are "robin's egg blue," and the color of the blue sky. Inferior grades are greenish. Turquoise that fades in color is also inferior. Turquoise is a phosphate of aluminum with small quantities of copper and also iron. The gem is slightly harder than glass.

Ancient and yet always at the height of the current fashion: that is Turquoise for you. Its brilliant sky-blue belongs to the all-time favorite trend colour in the world of fashion and jewellery.
