About This Band

Square princess-cut lab-grown diamonds sit edge to edge across the top of this platinum men's wedding band, forming one unbroken row. Two smooth metal walls hold them in a channel with no prongs between the stones. The band has a flat top and straight polished sides, and the stones stop at about a third of the way around, leaving the back plain.

  • Metal: platinum
  • Lab-grown diamonds: princess cut, set side by side in a single row
  • Total weight: 0.50, 0.75 or 1 ct
  • Setting: channel set between polished walls
  • Profile: flat top, straight sides, plain polished back
  • 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)
