This is a darling vintage Celtic Claddagh heart ring marked "Irish" on the inside band. It's a size 6 (on the smaller side) and in good, gently used condition with traces of silver polish. It comes from a smoke-free home (although we do have dogs). I don't know what the green stone is but it's very pretty - one fellow Poshmark pal said it is likely "Conamara marble, which is found in Ireland."
