💰Abalone ring, mother of pearl, size 6.5

Abalone ring, mother of pearl, iridescent moonstone/ mood ring type look but with natural elements. size 6.5 I wear a 6.25 or a 6.5 on my ring finger so if that helps Abalone I think I bought this in a gift shop in either Canada 🇨🇦 or Estes Park Colorado (can’t remember which place but I remember the gift shop lol) Can’t guarantee that the silver toned metal is sterling because it doesn’t have the stamp in it. It might turn your finger green for all I know?
