These earrings are one-of-a-kind pieces and are subject to prior sale. Any of the dangle earrings can be converted to screw-backs or clip-backs. Sterling wires can be replaced with gold or stainless steel. Contact us at newmansdesign@comcast.net for the charges to do the conversion. The sizes given are for the earring proper and don't include the wire or post. The wires are sterling and handmade unless otherwise noted. Making earrings is fun and spontaneous for us and we hope they will provide lots of enjoyment for you too!
