This hidden halo engagement ring pairs a 2-carat oval cut lab-grown diamond center stone with a halo of diamonds tucked beneath it, adding sparkle without changing the ring's clean, simple silhouette.

  • 2mm band width — creates a balanced, comfortable profile suited to everyday wear.
  • Hidden halo setting — positions accent diamonds beneath the center stone, adding brilliance without a raised silhouette.
  • 18 round diamond accents — (0.06 ct. tw.) in a scalloped pavé setting frame the gallery beneath the center stone.
  • Perfect fit design — lets this ring sit flush with a wedding band for a gap-free look.
  • D-F color, VS clarity — grading keeps the center stone bright and clear.
  • Precious metal options — let you choose the one that suits your style.

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