Description

Montana Sapphire™ is cut from gem rough found in the mountains of western Montana; this gemstone displays an attractive medium-blue color and is an ideal addition to custom jewelry designs. Sapphire is the birthstone for September.

Sapphire (like ruby) is a gem variety of corundum classified as a precious stone. Sapphire is hard and durable, and is found in a wide range of colors, making it an extremely versatile stone suitable for any form of jewelry. Sapphires in any color other than blue are referred to as 'fancy' sapphires. Sapphire gets its color from titanium and iron oxides; the depth of color depends on the amount of oxides in the stone. In ancient times, some believed that the sky itself was an enormous sapphire into which the Earth was embedded; sapphires are credited in folklore as being sacred, of conveying wisdom, prophecy and divine favor.

Rio is proud to offer the American Mined™ Collection, a growing selection of gemstones sourced from mines located here in America. These gemstones consistently present the excellent color, clarity and quality we look for in every stone we offer you. Each of these gemstones allows us to provide a clear, documentable path from the mine to your bench; you and your customers can be confident that every one is mined, cut and processed under conditions that meet all standards for worker safety, environmental protection and responsible production.

The cushion cut is a classic style; it combines features of the oval cut with a deep cut and large facets.
