Sterling Silver 925 JCM Connected Circles on a 18” Rolo Chain Necklace.

Sterling Silver 925 JCM Connected Circles on a 18” Rolo Chain Necklace. Spring ring clasp. The two hammered rings are linked together by a smaller ring. Maybe symbolic of a couple with a child? Marked “925 JCM” on the ring next to the clasp, and the clasp itself is marked “925”. Minimalist design. I ‘be tested the metal in the clasp, chain, and the rings. They’re all sterling. Could probably use a little polish, but otherwise in good condition.
