This is a beautiful Victorian Art Nouveau style bracelet. It is not marked and I do not know who made it. The bracelet appears to be stamped brass. There are 3 bezel set onyx stones set in the 3 middle links. The bracelet measures 6-3/4 inches long. It is 3/4 of an inch wide. The bracelet is in good condition but may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
