Sapphire is a gem variety of the mineral corundum. It occurs in every color except red, which is reserved for the “ruby” variety. The finest sapphires are of a deep blue color, but pink, purple, yellow, and green are also popular. All colors other than blue are known as “fancy color” sapphires.

The finest sapphires come from Myanmar and Sri Lanka. Montana has also produced fine sapphires, but of generally smaller size and less abundance. Most of the stones in this display are from Sri Lanka.
