This halo engagement ring layers round diamonds around the center stone in a shared-prong setting for a rounded, balanced silhouette full of sparkle, light, and lasting, everyday brilliance.

  • 2mm band width — gives the ring a balanced, comfortable profile for everyday wear.
  • Four prongs — hold the center gem secure at the halo's center for balance.
  • Shared-prong halo diamonds — are set around the halo (0.49 ct. tw.) for added sparkle.
  • Shared-prong construction — keeps the halo compact and reduces visible metal between adjoining diamonds.
  • Low-profile fit — the setting keeps the center stone close to the finger, supporting everyday wear and comfort.
  • Rounded halo outline — suits a range of center stone shapes for a classic look.

Beautiful!

When my fiance proposed, I was blown away by this beautiful ring! It is elegant and timeless. Further, the slightly lowered profile makes it suitable for everyday wear.
