These are freshwater pearls ? most of them copper-colored ? teamed with oxidized sterling silver fittings. The earrings are for pierced ears; the necklace is 17" long, with a toggle clasp. Erica Zap designed this stunning ensemble herself, and the pieces were made in her studio on Newport?s historic Thames Street. Treat yourself or someone special to this exquisite adornment ? the freshwater pearl and oxidized sterling silver necklace and earrings.
