About White Sapphire

White Sapphire, also known as “Leucosapphire,” is actually colorless and the purest form of Corundum, lacking additional trace minerals that color other Sapphires.

It is less in demand than other Sapphires and reasonably inexpensive, and is often used as a Diamond substitute, usually as smaller stones with good clarity and few visible inclusions. White Sapphire can occur in almost any Corundum deposit, but gem-quality stones are exceedingly rare
