Amethyst & Sapphire Sterling Silver Heart Ring

Amethyst and Sapphire Sterling Silver Heart Ring Size 4 (14.8mm across). It needs to be polished but I don't know where I put my silver polish. :( It has a teeny-tiny diamond on each side of the ring. It is technically pictured, but you really can't see it. I got it from a legit jewelry store, but I don't remember which one. The ring DOES NOT come with the box. The box is only there for pictures. 12
