So fantastic. 3/4" (including ring at top) x 3/8". Black enamel is mildly chipped and scratched but only visible under magnification. Glass locket at back has braided hair underneath, but we could switch it out for you if you like. c. 1850-80, but SO GRAPHIC for the era! It looks like a cartoon, or emoji, or illustration. No engraving, so it can be a sort of generic mourning jewel. Testing 15k gold.
