As we turn our calendars to September, we start thinking of things like heading back to school, sipping on a pumpkin spice latte, and planning our fall fashions. For those celebrating a birthday in September, they鈥檙e thinking of their birthstone: sapphire!
Although sapphire typically refers to the rich blue gemstone variety of the mineral corundum, this royal gem actually occurs in a rainbow of hues. Sapphires come in every color except red, which would then be classified as ruby.
Trace elements like iron, titanium, chromium, copper, and magnesium give naturally colorless corundum a tint of blue, yellow, purple, orange or green, respectively. Sapphires in any color but blue are called 鈥渇ancies.鈥�
Pink sapphires, in particular, tow a fine line between ruby and sapphire. In the U.S., these gems must meet a minimum color saturation to be considered rubies. Pinkish orange sapphires called padparadscha (from the Sri Lankan word for 鈥渓otus flower鈥�) can actually draw higher prices than some blue sapphires.
Due to the remarkable hardness of sapphires鈥攚hich measure 9 on the Mohs scale, second only to diamond鈥攖hey aren鈥檛 just valuable in jewelry, but also in industrial applications including scientific instruments, high-durability windows, watches, and electronics.
Sapphires make stunning gifts for anyone born in September or celebrating a 5th or 45th wedding anniversary, so be sure to visit an AGS jeweler. They will help you find that perfect gift, whether you鈥檙e seeking the classic blue or another shade from the sapphire rainbow.
