I’m curious about the quality and material of these two rings my mom gave to me! The gold one was a gift from my grandfather to my grandmother when my mom (59) was in college. I see some kind of makers mark on the pearl ring. Wondering about the pearl origins (salt water?), and the gems of the gold ring as well as the gold %. The mark on the gold ring is fairly worn. Thanks!
