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

Plain from above, a surprise from the side.

The 5 ct heart-shaped lab-grown diamond center comes set in this ring, gripped by claw prongs on a raised head. Look straight down and you see only that one stone. Tilt the ring and an unbroken circle of tiny lab-grown diamonds appears, tucked just beneath the center. Along the upper half of the slim, rounded band, a single row of round lab-grown diamonds shares prongs on both sides, down to where the band meets the sides of the finger; the lower half is smooth platinum.

  • Main stone: 5 ct heart-shaped lab-grown diamond, included
  • Under the center: a hidden ring of small lab-grown diamonds
  • Upper band: one row of round lab-grown diamonds, shared prongs
  • Lower shank: plain and polished
  • Made in: Platinum

Wear it with: a plain band in the same metal, so the side view keeps its surprise.
