This engagement ring pairs a 4-carat oval cut lab-grown diamond center stone with round diamonds set in shared prongs that line half of the band for a light, airy look.

  • 1.8mm band width — creates a slim, comfortable profile for everyday wear.
  • Shared prong accents — line half of the band, keeping the design light while extending sparkle beyond the center stone, shaped to keep the setting compact and the center stone as the focal point.
  • Half-coverage design — leaves the remaining half of the band smooth and plain, balancing sparkle with simplicity.
  • 16 round diamond accents — (0.23 ct. tw.) continue the brilliance from the center stone down the shank.
  • 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.

What customers are saying

Customers love the sparkle and quality of the center stone, with many describing how it catches light from every angle and draws constant compliments on its brilliance. The slim petite band sits comfortably enough that wearers forget they are wearing it while letting the diamond take full center stage. Many say the ring far exceeds what they expected at the price, and several describe it as a timeless piece they plan to pass down.
