Description

This single, special-order 7.5mm step-cut square sapphire is available due to a misdirected order; take advantage of a rare opportunity to order this beautiful gemstone. The vibrant blue of this AA-grade sapphire makes it one of the most popular stones for use in jewelry. While traditionally set in white metal, setting blue sapphire in yellow gold, especially high-karat gold, creates an appealing effect. 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 oxide 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.

This square stone features step-cut faceting with square corners typical of a princess-cut stone. The facets' concentric planes resemble stair-steps from corner to corner around the four sides of the stone, above and below the girdle.
