Sapphire is a gem quality variety of the mineral corundum. It is the second hardest substance on earth after diamond, rating 9 on the Mohs scale of mineral hardness. Corundum itself is not a very rare mineral, but gem quality corundum is extremely rare.
While blue is the most traditional and classic color for sapphire, sapphire is actually found in a variety of different colors. Most natural sapphire is quite pale and light in color. Only a small percentage of natural sapphire exhibits vivid and intense colors without some type of treatment or enhancement, the most common being heat-treatment. For many years, only blue sapphire was recognized as 'true' sapphire. Today, all colors of gem quality corundum are known as sapphire, with exception to red corundum, which is classified as ruby. There is no definitive demarcation between red ruby and sapphire; in most cases, near-red sapphire would be classed as inferior colored ruby. Thus, it is common practice to trade near-red sapphire as a quality fancy color sapphire, rather than as a lower grade ruby.
Colored sapphire (other than blue) is often referred to as fancy sapphire, and fancy sapphire is typically traded using color-specific names, such as yellow sapphire, green sapphire or purple sapphire. In the past, there were several misleading names used for fancy sapphire varieties, most of which are no longer used, such as 'Oriental peridot', a term which was used to refer to green sapphire.
Sapphire is found in only a few locations in the world. The three most famous regions for blue sapphire are Kashmir, Burma and Sri Lanka. Sapphire has also been mined in Cambodia, Thailand, Vietnam, Africa and India.
