About This Band

A polished strand and a stone-set strand wind around each other across this platinum band and cross at the front in an infinity-style twist, giving the side profile a gently wavy line. The set strand carries a continuous row of small round lab-grown diamonds in fine shared prongs, close enough to nearly touch. The row covers about the top half of the band, and the lower half is plain polished metal.

  • Lab-grown diamonds: small rounds, close-set along one strand
  • Total lab-grown diamond weight: 0.15, 0.25 or 0.35 ct
  • Design: infinity crossover of a set strand and a polished strand
  • Coverage: half eternity, the top half of the band
  • 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.
