70s vtg Necklace / Belt

This Interlocking Ring Loop Necklace is from my personal collection I wore as a necklace but if ur waist is small u can wear as a belt too Unsure material. Never tested to see if it was bakelite, resin, celluloid etc So I always default to saying its plastic. Still a gorgeous piece! its about 30” excluding extender hook Super lightweight I do not accept lowball offers circle chainlink goldtone art deco avant garde
