Marquise Faceted Genuine Blue Sapphire

Sapphire is one of the most popular colored stones in the United States with extraordinary durability, suitable for everyday wear. Trace elements of iron and titanium cause the blue color of sapphire. In fact, pure corundum, the mineral Sapphire is composed of, is actually colorless. However pure corundum is rare, with trace elements responsible for the wide range of colors available. Sapphire is the birthstone for September. Clean with warm, soapy water. Use of ultrasonic and steam cleaner is usually safe.
