Fun black enamel necklace & earrings

I think the pendant (about 1-3/4" with bail) and earrings (about 7/8") are in pewter - in any even, the metal has a nice tone. The chain in rounded snake style is just over 15" with an extender just over 3". All in very good shape, with perhaps some like scratches on the enamel, easy to shine up!
