Cut to catch light, then give it back.

About this ring

One sharp line to the center.

Both faces of the platinum band slope inward and meet in a crisp ridge along the top, and that ridge carries on unbroken until it reaches the base of the head. The head lifts a single center above the band, its prongs narrowing into a V beneath the stone when seen from the side. There are no accent stones, only polished metal. The center, a marquise center, is chosen in the next step.

  • Center: marquise, chosen in the next step
  • Style: solitaire
  • Band: knife-edge ridge, high polish
  • Head: raised prongs, V-shaped profile
  • Metal: platinum

Wear it with: a matching knife-edge band, so the two ridges line up side by side.
