Marquise Faceted Genuine Blue Sapphire

Sapphire is one of the most popular colored gemstones in the United States, prized for its extraordinary durability and suitability for everyday wear. Pure corundum — the mineral from which sapphire is composed — is actually colorless in its purest form, but trace elements of iron and titanium produce the iconic blue color associated with sapphire. These same trace elements are responsible for the wide range of colors found across the corundum family. All stones in this selection are heat-treated and available in four quality grades, allowing jewelers to match the right stone to any project or price point. Sapphire is the traditional birthstone for September.

These marquise faceted genuine blue sapphires are sold individually and are suitable for setting in fine jewelry, custom designs, and resale applications. Clean with warm, soapy water. Use of ultrasonic and steam cleaners is generally safe for heat-treated sapphire.
