Light breaking into color through a lab-grown diamond

Light performance

Cut to catch light, then give it back.

Excellent cut, polish and symmetry. An ideal cut returns more of the light that enters it than most stones its size.

About this ring

Carved sides, a raised arch.

The shoulders of this rose gold setting climb into an open arch beneath a prong head that holds a fancy blue marquise center, chosen in the next step. Along the top of each shoulder, a line of small bead-set lab-grown diamond accents reaches toward the sides of the finger, and a few more are tucked into the gallery under the center, where they show from the front. Both outer sides of the band carry a repeating carved ridge for an antique look.

  • Center: marquise, chosen in the next step
  • Metal: rose gold
  • Lab-grown diamond accents: 0.15 ct total
  • Profile: cathedral arch under the head
  • Band: carved ridges on the sides, plain ridged base

Wear it with: a slim plain band, so the carving on the sides stays visible.
