Description

This AAA-grade round faceted sapphire displays the deep blue color that makes it one of the most popular gemstones; the stone's hardness makes it one of the most versatile. This stone shows the superior cut, color saturation and active scintillation required to be classified as a top-quality AAA-grade stone. Use it by itself for petite earring designs, or highlight its color by pairing it with contrasting-color stones to create more complex, multicolor 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.

Round-cut gemstones are highly popular and the most commonly available. Rio round gemstones are calibrated for size and hand inspected to ensure maximum attractiveness.
