This is a silver tone choker necklace with faux marcasites and black enamel cabachons. The necklace is not signed and I do not know who made it. The necklace measures 17-1/2 inches long and 1/2 of an inch wide. The necklace is in very good condition and appears to have been gently worn, if at all. Please let me know if you have any questions. Thanks for stopping by.
