MCM (Mid Century Modern) copper pendant necklace is super Post Modern from the 40s to 50s. It has dimension! The abstract coil on the pendant stands out. Chunky curb twist chain has some dull tarnish, closes with working spring ring. The pendant is very shiny but not perfect as you can see in photos. No maker marks. 18" long, comes in a gift box
