7 strand rice pearls necklace gold tone round box clasp with Faux pearl

7 strand rice pearls necklace, gold tone round box clasp with Faux pearl . 24" long and weighs 85 grams on my kitchen scale which equal 2.99 ounces... which surprises me I thought they would weigh more they have such a nice weight . Not sure if they are real cultured rice pearls or glass . The clasp is stamped with SILVER now not sure if that means sterling with a Gold Vermeil electroplating ... a magnet will not stick to the clasp. Or perhaps that is the name of the company that made it SILVER ?? They are very versatile wear them twisted ( pic 2 ) or just loose ( pic 3) . Wear them to a fancy dinner, wedding , Valentines' Day . cocktail party, or less formal occasion with a sundress or to the office under a collar short ( they feel great against the skin). Dress forms neck measures 15". Some wear on the clasp see pic 4 ..wear consistent with use and age . Questions are always welcome. Special occasion, Valentine's Day, Cocktail party, bride, wedding guest , formal, informal, everyday , rice pearls
