This is a gorgeous pair of Enamel Earrings. These measure approximately 1 inch round. The base metal is copper. The ear wires are sterling silver. The enamel is lead-free.
Hand-crafted art/jewelry are one-of-a-kind pieces and generally are not duplicated exactly. Stones vary, measurements vary. I can collaborate with you if you would like to have a piece made for you or for someone else. Sterling silver may be polished with any number of good silver cleaner/polish products. Natural stones are fragile and may break if dropped, heated directly, stepped on, etc. Care should be taken.
