About This Band

The top of this platinum wedding band dips into a deep U shape, leaving an open space meant to sit around the center stone of an engagement ring. A princess-cut lab-grown diamond marks each end of the curve. Every stone is held at its corners by prongs on a square basket with solid, flat metal walls on its sides, which keeps the outline crisp and straight-edged. Beyond the stones the band is plain and polished, with flat sides.

  • Lab-grown diamonds: princess cut, one at each end of the dip
  • Total lab-grown diamond weight: 0.50, 0.75 or 1 ct
  • Setting: corner prongs on square, solid-walled baskets
  • Shape: deep U-shaped curve with an open gap between the stones
  • 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.
