Peridot (PAIR-ee-doh), August's birthstone, is also known as Olivine and Chrysolite. The intensity of Peridot's zesty lime green color is dependent upon the amount of iron within the stone. Peridot's perky color makes this stone a perfect compliment to bright summer fashions. It is said that the Queen Cleopatra's extensive "emerald" collection was actually a large collection of high quality peridot. Peridot was a wildly popular gem in the Baroque period, and is once again gaining in popularity. Peridot pairs well with sterling silver, Swarovski crystal and magnetic hematite beads.
