Necklace measures 15" long (just a tad over) so it is a true collar piece. If your bigger than that you will need an extender. All the stones are prong set - no dead or missing. The earrings are clips - tight and secure. The plating is not in excellent condition - I am not sure the clasp is original but it is secure. All the topaz stones in this set are crisp. If your looking for authentic Retro Rockabilly this is it. Of course it's a one and only for me.
