Sterling Silver Mahawu Round and Marquise Shape Peridot Drop Earrings. Our Sterling Silver peridot marquise shaped earrings with round center, are handcrafted in Bali by our skilled artisans.

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.
