Sapphire is a variety of Corundum, an aluminum oxide mineral that forms in prismatic tabular, bipyramidal or rhombohedral crystals, as well as granular or massive habits, and may be transparent to opaque. The name Corundum is of Indian origin, derived from the Sanskrit korundand applied to opaque massive gems, generally of a dull color. With the exception of Red Corundum, which is Ruby, all other colors of Corundum are Sapphires. [Simmons, 339][www.mindat.org][Fernie, 140]
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 Gemstones can occur in almost any Corundum deposit, but gem-quality stones are exceedingly rare.

What is Corundum and What are its Basic Qualities?
A: Corundum is an aluminum oxide that commonly forms hexagonal barrel-shaped prisms that taper at both ends or as thin tabular hexagonal plates. It has a hardness of 9 on the Mohs scale, making it one of the most durable commercial gemstones. It has no dominant cleavage and fractures in a conchoidal manner. A high density of ~4.0 g/cm3 (most silicate minerals are ~2.6 g/cm3) results in corundum occurring in secondary placer deposits and recoverable by panning methods, similar to how you would recover placer gold.
Corundum comes in all colours of the rainbow but is most commonly found as opaque crystals with dull colours. Red corundum is called ruby, blue corundum is called sapphire, and all other colours are called fancy sapphires. Some varieties of corundum will fluoresce under short wave and long wave UV light if there is enough chromium in the crystal structure but little iron, which tends to quench any emitted energy.
