Details: This urchin was cast from a shell my husband found on Pawley's Island in South Carolina. I make them from fine silver and string them on a sterling silver chain which measures to 18" (length adjustable) and closes with a hook and eye clasp. It is a heavy little pendant, but just dainty enough. It is 5/8ths of an inch wide and oxidized then polished. Please allow up to four days for manufacture.
