About This Ring

A marquise-shaped lab-grown diamond sits on each side of the center of this ring, and more marquise and round accents follow in a single alternating row down both shoulders. Each accent is held on its own, with a little metal showing between them, and the row stops at the sides of the finger, leaving the lower band smooth. The 8 ct radiant-cut lab-grown diamond center comes set in the ring, in an open four-prong head.

  • Center: 8 ct radiant-cut lab-grown diamond, set in the ring
  • Side accents: lab-grown diamond marquises and rounds, alternating in one row
  • Band: slim, flat-topped, plain polished metal on the lower half
  • Metal: platinum
  • 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.
