Symmetalic was the registered trade mark of the W. E. Richards Company found on their high quality sterling jewelry. This necklace and earrings are sterling and faux blue moonstones. The necklace is 14" long and closes with a fold over clasp. The screw back earrings are 1". Marked Symmetalic and 1/20 14 K gold, but there isn't a speck of the vermeil left, most likely removed the gold professionally. Excellent vintage condition. I have made a sterling extender that has a large loop to fit the wide fold over clasp.
