Antique arts and crafts sterling cameo ring, authentic size 6

i've been researching my family tree information and it definitely has me in the mood for honoring my ancestors. wearing adopted ancestors feels right to me. this is a lovely antique arts and crafts cameo ring, made in sterling with a hand carved shell cameo. i think it's gorgeous, and slipping it on my own finger was maybe a mistake. i think it's probably been sized, and done nicely. condition is quite good. i haven't attempted to clean the cameo but happily will if desired.

size: measures a 5.5, fits more like a 6
height of face: 7/8"
width of inner band: a bit over 1/16" authentic
