Quick Tips
- Measure at the end of the day, when fingers are largest.
- Snug, not tight — the ring should pass your knuckle with slight resistance.
- Wider bands (4mm+) fit tighter — consider sizing up half a size.
- Between two sizes? Always size up.

Our Princess Double Halo Lab Grown Diamond Engagement Ring with Triple-Row Split Shank is the ultimate expression of diamond luxury — a show-stopping statement piece that commands attention from every angle. A magnificent 2.60ctw princess-cut lab grown center diamond is set in a 4-prong corner setting at the heart of two concentric square pavé halos, while the band splits into three separate strands of pavé-set round lab grown diamonds along each shoulder, creating an extraordinary 5.20 total carat weight.
The square double halo perfectly echoes the angular geometry of the princess cut, amplifying its presence and creating a bold, symmetrical silhouette. An ornate filigree and scroll openwork gallery beneath the double halo reveals exquisite metalwork detail from the side, adding a vintage-inspired dimension to a thoroughly modern powerpiece. The three diamond strands of the split shank converge into a single plain polished band at the base for elegant contrast.
Available in 10K/14K/18K White, Yellow, or Rose Gold and Platinum.
