From the Jewelry Blog: This dainty Spiderweb Heart Locket Necklace from Anne Koplik features Chalcedony and Lilac Swarovski Crystals set into a bronze spiderweb pattern with an antique bronze patina. Anne Koplik always uses lead and nickel-free metals. The chain is adjustable from 16" to 18" with a lobster claw clasp. Matching earrings also available. A great romantic gift idea!
