Turquoise has been hugely popular for thousands of years. The history of this stone can be traced back to around 6000 BC. During the reign of the ancient Egyptian Pharaoh Semerkhet, mining operations were being carried out which involved thousands of workers.
Birthstone for December, turquoise is one of the few minerals to have given its name to a colour. Whilst most people think of it as being a shade of bluish green, the colour can vary from apple green to sky blue.
