Turquoise | December Birthstone

Last December we looked at Zircon and Tanzanite, but there is another stunning December birthstone we would like to talk to you about today.   Turquoise is found in only a few places on earth.  Mainly dry and barren regions where acidic, copper-rich groundwater seeps downward and reacts with minerals that contain phosphorous and aluminium.  The result of this process is a porous, semi translucent to opaque compound of hydrated copper and aluminium phosphate.  Turquoise is a great example of an opaque coloured stone that can be marketed both as a gem for jewellery and as an ornamental material.
