The closest thing to the Platonic ideal of a ring has got to be the Nudo. By Italian jeweler Pomellato, it’s a perfect faceted hunk of a gemstone affixed, sans visible prongs, into a substantial 18-karat rose gold band. Minimal enough to accompany edgy apparel yet classic enough to be worn by your grandma, it’s designed to be stackable (a nice touch). Last month, Pomellato introduced a new Nudo size (bigger!) and color (blue topaz). Buy it and you’ll pass it down to your granddaughter someday.
