Vintage Gold tone & Black Leather Chain Necklace/mark is seen on gold tone beads

This high end interesting necklace is a combination of gold plated metal and possible real or faux leather. It is very well-made by an unknown maker (OOOO)and closes with a fold over clasp. No signature appears unless the design on the oval joints. This piece has a mid century modern look. 💐Very cool. 🦋🌸
