Sapphire Description & Origins
Although the classic blue sapphire jumps readily to mind for most people, sapphire may refer to any corundum other than those with a rich, blood-red color, which is instead called a ruby. Often the term “fancy” is used when referring to a colored sapphire other than blue.
In order to form, the mineral corundum requires a silicon-free environment, which is unusual given how common silicon is on earth. As such, natural sapphires are rare and highly valued. Sapphires come from many locations around the world including Australia, Thailand, Madagascar, Myanmar, Tanzania, and Sri Lanka.
