Sapphire Stunners: September's Gorgeous Birthstone

Sapphire Stunners: September's Gorgeous Birthstone

Did you know sapphires actually come in almost every color of the rainbow? This is just one of the many little-known facts about sapphire, September's (and Beyonce's) birthstone. 

About Sapphire

Sapphire is one of the four precious gemstones. It is from the mineral species corundum, and although blue is the most common shade, sapphire can be found in almost every color: gray, black, white, violet, green, yellow, orange, pink, purple, and all the shades in between. 

The term sapphire can apply to any corundum variety except for ruby; since true red corundum stones are so rare, they are called rubies (which are also precious gems) instead of sapphires.

Sapphire originates from several locations around the world, including the state of Montana, a few regions in Africa, Australia, Sri Lanka, Kashmir, a few regions in Southeast Asia, and China. 

Its score on the Mohs Hardness Scale is 9 out of 10, making sapphire an ideal choice for engagement rings. It's hard enough for synthetic sapphire to be used in spacecraft.

Symbolism & Folklore

Sapphire is the birthstone for September and the gem for 5th and 45th anniversaries. Traditionally, it symbolizes nobility, truth, sincerity, and faithfulness.

In ancient Greece and Rome, sapphires were worn by the elite to protect their owners from danger and envy. European royalty wore sapphires for the same reasons, and even the clergy of the Middle ages wore sapphires to symbolize Heaven. 

Princess Diana's iconic engagement ring from Prince Charles featured a beautiful blue sapphire centerstone, and the same ring is now found on Kate Middleton's finger as her engagement ring.
