This three-stone engagement ring features a prominent center stone with two matched pear-shaped diamond accents for a balanced, symbolic design that highlights refined craftsmanship and light.

  • 1.8mm band width — creates a slender profile that suits the center stone.
  • Claw-prong basket setting — holds the center gem in an open, focal-point arrangement.
  • Two pear-shaped side stones — sit in three-prong baskets beside the center stone (0.37 ct. tw.).
  • Gallery wire — beneath the center stone adds extra support and reinforces the setting.
  • Gallery and prong accents — introduce detail at multiple angles for added sparkle.
  • Low-set profile — keeps the center gem close to the finger, adding comfort for everyday wear.

This Most Loved piece displays the best and brightest in fashion and design and is beloved by Brilliant Earth designers and customers alike.
