Precious
After diamonds, sapphires are the next hardest gemstone and one of the most valuable. Sapphires belong to the corundum family of rock minerals, which occur in many colours. All colours, other than red corundum, are known as sapphires, with a blue sapphire being the most coveted even though other colours may be rarer. Sapphires are stunning set in white gold, such as Sheila's Celtic Trilogy
