September Birthstone: Sapphire
September’s stone is sapphire. It is cut and moving in the Collection.
Sapphire is corundum coloured by iron and titanium. Kashmir’s velvety blue, mined out within a decade, is still the standard the trade measures against.

Fine rutile inclusions in some sapphires scatter light into a six-rayed star known as an asterism.
