Symmetalic Blue Moonstone Necklace and Earrings Set Sterling Silver plus 14K Gold Filled. Symmetalic was owned and operated by the W E Richards Company which signed most of its jewelry as wRe. Jewelry made by this company is known for superior construction and is highly prized by estate jewelry collectors. Real gemstones frequently appeared in their jewelry, but synthetic stones were also used. The earrings are screwback and the necklace clasp is a foldover. All pieces are marked Symmetalic Sterling plus 1/20 14K GF. This means that both necklace and earrings are made from one layer of gold filled metal and one layer of sterling silver. This Symmetalic jewelry set shows 5mm blue moonstone cabochons sitting on a crescent moon in the front part of the necklace. The necklace is 16 inches long. The earrings sport moonstone cabochons measuring 10mm by 12mm. Necklace and earrings are in very good condition.
