Gold chains never go out of style. You find them in antique shops, vintage boutiques and retail stores from high end to dollar stores stock them. They go with everything and this is one of the best vintage pieces I've come across in a long time.
This triple strand consists of two flat snake link chains and one rope chain all meeting in the back in a flat snap down clasp. The chains are 30 inches long. The clasp means the necklace can be doubled to make a collar length if you have a thin neck, and wrapped around your wrist several times and fastened.
I'm not sure if this is gold tone or plated. The snake chains feel like plate to me. The necklace is not marked but is a solid piece in great condition.
