Birthstone Jewelry: Sapphire Is the Birthstone of September

Summer may be coming to an end, but those with September birthdays can delight in the diversity of colors available in sapphire, the birthstone of the month and the hardiest gemstone around after the diamond. Found throughout the world in “violet, green, yellow, orange, pink, and purple,” according to the Gemological Institute of America, sapphire is a chameleon of a rock with a respectable refractive index and worldwide appeal for its beauty and durability (a 9 on the Mohs Scale). Here are nine new sapphire jewelry styles.
