About This Band

This slim, low platinum band alternates two motifs across its top: a larger round lab-grown diamond held in prongs, then an open marquise-shaped metal frame holding a short row of tiny round lab-grown diamonds set with beads. Larger stones sit at the top center and toward each end of the set section, so the outline swells and narrows along the row. The frame edges are smooth and polished, and the lower half of the band is plain metal with a flat, even profile.

  • Lab-grown diamonds: rounds, larger prong-set stones and small pave-set stones
  • Total lab-grown diamond weight: 0.25, 0.35 or 0.50 ct
  • Details: open marquise-shaped frames between the prong-set stones
  • Coverage: across the top of the band only
  • 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.
