This nature-inspired engagement ring pairs a 3-carat round cut lab-grown diamond center stone with marquise-shaped diamonds that wind like vines around the band.

  • 4mm band width \u2014 gives the ring a substantial, comfortable profile on the finger, finished for comfortable, everyday wear.
  • Vine-inspired metalwork \u2014 winds toward the center stone for an organic, nature-inspired silhouette.
  • Signature organic design \u2014 carries the vine motif around the band for a distinctive, one-directional flow.
  • 16 marquise-shaped diamond accents \u2014 (0.52 ct. tw.) create the winding vine pattern around the band.
  • D-F color, VS clarity \u2014 grading keeps the center stone bright and clear.
  • Precious metal options \u2014 let you choose the one that suits your style, shaped to keep the setting compact and the center stone as the focal point.

This center lab diamond is certified for authenticity by an independent grading lab and inscribed with a number that matches its certificate.
