Sapphire

Treasured all over the world, sapphire is considered to be one of the four precious gemstones, along with diamonds, rubies and emeralds. Sapphires have always been a popular stone, but increased in appreciation when Lady Diana Spencer received a blue sapphire and diamond engagement ring from Prince Charles.

Sapphires are thought to be mind-opening gems. They are supposed to relax the wearer and clarify thought, as well as attract "divine favor." Sapphire is said to prevent envy and fraud, and bring truth and good health. They were believed to be a powerful antidote for poison.

Interestingly, not all sapphires are blue. Because it is a species of corundum, the red variety is classified as ruby. Sapphires can be found in violet, green, yellow, orange, pink and white, which are popular as diamond imitations. Blue is the most abundant, and therefore, the most popular.

Sapphire is a variety of corundum.

Sapphires rate a 9.0 on the Mohs scale, making them one of the hardest gemstones, second only to diamonds. They are extremely durable and perfect for everyday wear.

Sapphires can be treated in any number of ways. Heat treatment is commonly used to improve color and clarity. Irradiation may be used to enhance yellow or orange sapphires. Fracture or cavity‐filling uses oil or epoxy resin to hide fractures and improve clarity. Such treatments should be disclosed during the buying process.

Sapphire is the traditional birthstone for those born in September.

One of the hardest gemstones, sapphires should be stored separately from others so as to not scratch them. Steam and ultrasonic cleaners are generally safe, unless your sapphire has been fracture or cavity‐filled. For best results, clean your sapphire jewelry using a mild soap under warm running water and dry with a soft lint‐free cloth.
