Sapphire Round Cabochon

The light-to-navy blue color of this round sapphire cabochon makes it one of the most popular gemstones for use in jewelry and is an ideal choice for simple ring and earring designs. While traditionally set in white metal, setting blue sapphire in yellow gold, especially high-karat gold, creates an appealing effect. Fancy sapphires are valued for their brilliant color and economical price. Because they are natural gemstones, any given gem may contain natural impurities but will offer excellent color and light-play. Sapphire is the birthstone for September. Sapphire (like ruby) is a gem variety of corundum classified as a precious gemstone. Sapphire is hard and durable, and is found in a wide range of colors, making it an extremely versatile gemstone 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 gemstone. 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.
