A Promise, Perfected

Emerald Cut Three Stone Engagement Rings

A 3 stone emerald cut engagement ring places one emerald cut center between two side stones. These are settings: you choose the center stone in the next step, and the side stones are lab-grown diamonds already set in the ring. Every design comes in white, yellow or rose gold, platinum, or Silvadium, a tarnish-resistant sterling silver, with side stones from matching emerald cuts to pears, baguettes and trillions.

Buying guide

Choosing the side stones

An emerald cut three stone ring, also called a trilogy ring, changes most with the shape of its side stones:

  • Tapered baguettes follow the straight lines of the emerald cut for a clean, architectural look.
  • Pear side stones curve toward the center and soften the rectangle.
  • Trillion and trapezoid side stones give a wider, geometric outline.
  • Marquise and round side stones add more sparkle beside the step-cut center.

Keep the side stones noticeably smaller than the center so the emerald cut stays the focus.

Band and detail options

Many designs add lab-grown diamond pave along the band. Others keep a plain band, add milgrain and engraving for a vintage look, use a split shank, or frame the center with a halo. A few bezel designs wrap metal around the center's corners for extra protection.

Center color and price

Most designs can hold a fancy-color center in pink, blue, yellow or green, and many also take a black center. The price shown is for the setting with its side stones: settings start under $250, and most are between about $900 and $1,350. The center is priced separately when you choose it.
