Oh, yes, they added marcasites to the sterling and carnelian to finish this original 1920's Art Deco necklace. Stamped sterling on pendant, it measure 15 inches plus 2 inch drop. The carnelian of the drop is an amazingly rich reddish brown. Sterling paper clip chain is original with a sterling spring clasp. It would be easy to make this longer and I would include it in the price - replace with appropriate antique chain or add an extender - length your choice.
