This three stone engagement ring pairs a 1.5-carat round cut diamond center stone with pear-shaped side diamonds for a classic, balanced silhouette.

- 1.5mm band width — gives the ring a slim, comfortable profile for everyday wear, showing craftsmanship that gives the ring a refined presence.
- Prong-set pear-shaped accents — flank the center stone (0.09 ct. tw.), adding brilliance on either side.
- Three stone design — builds visual weight around the center diamond for a classic silhouette.
- Complete preset design — includes the center stone already mounted in the finished setting, shaped to keep the setting compact and the center stone as the focal point.
- G-H color, VS2-SI1 clarity — grading keeps every stone bright and clear.
- Precious metal options — let you choose the one that suits your style.
This center diamond is certified for authenticity by an independent grading lab and inscribed with a number that matches its certificate.
