The GIA says that the finest sapphires are many times as rare as the finest “D-flawless” diamond!
Both sapphires and rubies are made of aluminum oxide mineral (corundum), and are exceptionally durable jewels. Corundum is rated “9” on Mohs Scale of Hardness, and that is good news. Rubies and sapphires can be worn every day.
Blue sapphires are often the most valuable and color variations are determined by the amount of titanium in the crystal. Kashmir sapphires’ distinctive cornflower is treasured.
Our favorite Sapphire this month is the Padparadscha. It is a delicate light to medium toned pink-orange to orange-pink hue corundum, originally found in Sri Lanka, but also found in deposits in Vietnam and parts of East Africa.
