Turquoise is a striking gemstone, the December birthstone.
Turquoise was one of the first gemstones to be mined, with some jewellery items dating back to 5000bc. The amount of copper and iron contained within the turquoise determines the colour -which varies from sky blue to green.
Turquoise is a calming stone and, because it aids tranquillity, is said to be a great stone to use in meditation.
