Vintage Silver-tone Round Omega Snake Chain with Pendant

Selling both chain and pendant together. Round and springy silver-tone necklace. Clasp sort of pops into each other. Not sure this would hold a super heavy pendant. A heavy pendant might pop the clasp open. The pendant is removable. Silver-tone metal chain with silver-tone and black enamel pendant in an oval shape. Size: Pendant - 1 1/4” x 1” approx Chain - 21” approx Length Chain - 3/16” width / thickness, approx This has some wear on pendant and the clasp. Nothing too bad. It’s hard to even capture it with photos. Just some slight variation in the silver-tone color. I don’t see any silvertone color loss.
