Traditionally sapphire symbolizes nobility, truth, sincerity, and faithfulness. It has decorated the robes of royalty and clergy members for centuries. Its extraordinary color is the standard against which other blue gems are measured. For centuries, sapphire has been associated with royalty and romance. The association was reinforced in 1981, when Britain's prince Charles gave a blue sapphire engagement ring to lady Diana Spencer. Until her death in 1997, princess Di as she was known, charmed and captivated the world. Her sapphire ring helped link modern events with history and fairy tales.
