Vtg. 1950's Renoir Copper Geometric Necklace

Good condition but needs to be lightly polished. I did polish a little bit to bring out the copper coloring. Still needs a more refined polish. Measures 13.25" long with a 4.75" extension. Stamped "Renoir" on the clasp. There's a black enameling on the inner part of each embellishment. Great collectible piece from the mid century era.
