Information and history of sapphires plus a gallery of sapphires used in antique and vintage brooches. The sapphire is the birthstone for September. It’s beautiful colour befits royalty so it is no wonder it was chosen as the engagement ring for Princess Diana in 1981.
Sapphire is one of the two gem-varieties of corundum, the other being ruby (defined as corundum in a shade of red). Although blue is the best-known sapphire color, they occur in other colors, including gray and black, and they can be colorless. A pinkish orange variety of sapphire is called padparadscha.
