This is an attractive vintage mod sterling silver double tiered necklace chain with hammered textured rings and discs. The necklace is marked 925 for silver on the clasp.
The shorter plain section of chain is 18.5" long and the longer chain with the decorative hammered rings and discs is 29" long. It weighs 20.1 gr.
Condition is good.
I estimate that this necklace dates from circa 1960s mod times up to 1970s, disco era. It's a fun swinging necklace, well made and ready to worn again.
