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 necklace

A heart, loosely gathered.

Round lab-grown diamonds crowd along the outline of an open heart, each one in its own prongs. They do not sit in a neat row: on the right lobe they pack into a dense cluster, while on the left they fan out in looser sprays, which gives the heart a hand-gathered, uneven look. The middle stays open. A single stone drops at the bottom point and another at the top notch, and a split-top rose gold bail carries the cable chain.

  • Stones: round lab-grown diamonds, prong set
  • Layout: asymmetric clusters and sprays
  • Shape: open heart
  • Bail: split top
  • Metal: rose gold

Wear it with: small cluster or round studs, kept simple so the heart leads.
