Description

Sapphire is one of the most popular colored stones 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 rich blue color these stones are known for. Pure corundum is rare in nature, and it is these trace elements that account for the wide range of colors found across the corundum family. These round genuine blue sapphire cabochons are heat-treated to enhance their color and are an excellent choice for setting projects, custom jewelry, and resale. Sapphire is the traditional birthstone for September.

Clean with warm, soapy water. Use of ultrasonic and steam cleaners is generally considered safe for these stones.
