sapphire
September's birthstone jewel
Sapphire is a precious gemstone, typically deep blue, prized in jewelry for its brilliance and hardness—second only to diamond.
Sapphires can occur in other colors (pink, yellow, white), but blue dominates the word's associations: sapphire eyes, sapphire waters.
A sapphire anniversary marks 45 or 65 years of marriage, depending on tradition.
