This three-stone engagement ring pairs pear-shaped side stones with the center stone for a classic, symmetrical silhouette built for comfortable, everyday wear.

  • 1.5mm band width — keeps the profile slim and comfortable for everyday wear.
  • Four-prong setting — holds the center stone secure, keeping the classic three-stone silhouette open to light.
  • Two pear-shaped side stones — are prong set on either side of the center stone.
  • Inward-facing side stone orientation — the pear-shaped side stones point inward toward the center, adding (1/10 ct. tw.) of sparkle.
  • Wedding band compatibility — the setting is designed to sit flush against wedding bands, creating a seamless, gap-free look.
  • Low, balanced profile — keeps the ring practical and comfortable for active hands and daily use.
