Some are stamped 925 and one is gold plated or gold filled I’m not sure which one it is but it is missing some stones and some have darkened from age. Old ring still a pretty one Rings have wear so please keep that in mind the Joseph Esposito one is signed Sterling and Espo it slightly sticks to magnet because it is rhodium plate over sterling silver. I know for a fact the clover one is sterling silver because I bought it for myself brand new rest are untested so please review photos as they are the best description They range in sizes and 2 are adjustable Does not come in ring holder
