The September birthstone is sapphire – a gem that’s been cherished for thousands of years. Although the term sapphire usually refers to the blue variety of corundum (ruby is the red variety), this birthstone comes in a rainbow of other colors. Sapphires have been long associated with royalty and romance and are also said to symbolize fidelity and the soul. “Sapphire” comes from the Greek word sappheiros and blue sapphire is one of the most popular colored stones.
