About This Ring

A classic three stone layout on a clean band: a fancy blue princess-cut center rises in an open prong basket, and a round laboratory-grown diamond accent sits right beside it on each side, each gripped by a separate set of prongs where the shoulders begin. Below them the band stays bare, with no cut-outs or twists, only smooth, high-polish metal with a rounded profile. You select the center in the next step.

  • Center: princess-cut, selected in the next step
  • Metal: platinum
  • Band: plain and polished, slender to medium width
  • Resizing: one free resize within 60 days of delivery; within one size it's done quickly, a bigger change means remaking the ring (about 10–15 days)

Made to order in 10–15 days, with free shipping on orders over $500 and 30-day returns.
