Samuel B. Sterling Silver 7mm Heart Shaped Peridot Stud Earrings. Our Sterling Silver peridot heart shaped earrings are handcrafted in Bali by our skilled artisans. From our signature collection, Royal Bali™ featuring designs handcrafted using sterling silver and genuine gemstones. The August birthstone, Peridot, symbolizes strength. It is sometimes called the “evening emerald” for its light green color. It was once believed that the green peridot crystals found in volcanic ashes were the tears of the volcano goddess, Pele. When set with gold, this gem was said to protect the wearer from nightmares.
