This is a Victorian or Edwardian necklace. It has a pendant with a center stone that is either black onyx or black glass. In the center is a rhinestone. The pendant appears to be gold wash over brass and the chain is also brass. The chain measures 16 inches from end to end. The pendant is 1 inch wide and 1-1/4 inches tall. The necklace is in good condition but does need polishing. Please let me know if you have any questions or would like to make a reasonable offer. Thanks for stopping by.
