Buying guide

How trapezoid side stones frame an oval

A trapezoid is a step-cut stone with four straight sides, wider where it meets the center and narrower toward the band. Set beside an oval, the pair of trapezoids leads the eye toward the middle stone and makes the whole top of the ring look longer and more tailored. Step cuts show broad, clean flashes rather than the scattered sparkle of a brilliant cut, which sets off the oval's brilliance by contrast.

Choosing your center

This page shows the setting. After you pick the metal, you choose the oval center in the next step, in the size you want. Fancy colors such as yellow, blue, pink and green are among the choices, and a colored center next to the trapezoid lab-grown diamond accents gives a bold, three stone look. A colorless center keeps the ring bright and classic.

Metal and price

  • Platinum or white gold keeps the side stones looking crisp and white.
  • Yellow or rose gold warms the ring and suits yellow or pink centers.
  • Silver is the lowest-cost option.

The setting starts under $450, and most options are about $900. That price is for the setting only; the center is priced when you choose it.
