About This Band

A chain of marquise-shaped frames, joined point to point, runs across the top of this platinum band and gives it a scalloped outline from the side. Each frame holds a single round lab-grown diamond, matched in size and caught by small prongs at the frame's points, with open space between stone and frame. Fine milgrain beading traces every frame edge for a vintage finish. The stones reach a little past halfway around, and the shank behind is slim and plain.

  • Frames: marquise shapes linked point to point
  • Stones: matched round lab-grown diamonds, each in its own frame
  • Total weight: 0.25, 0.35 or 0.50 ct
  • Detail: milgrain along every frame edge
  • Metal: platinum
  • Resizing: one free resize within 60 days of delivery; within one size it's done quickly, a bigger change means remaking the ring (about 10–15 days)

Made to order in 10–15 days, with free shipping on orders over $500 and 30-day returns.
