 This gemstone displays an attractive classic sapphire blue color and is ideal for 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 rugged and durable and comes in a wide range of colors, making it an extremely versatile stone suitable for any form of jewelry.  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 was an enormous sapphire into which the Earth was embedded; sapphires are credited in folklore as sacred, conveying wisdom, prophecy, and divine favor.

This square sapphire is calibrated for size and hand-inspected to ensure maximum attractiveness. These gemstones consistently present the excellent color, clarity, and quality we look for in every stone we offer you.
