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 Round Solid Cathedral Bypass Solitaire Lab Grown Diamond Engagement Ring pairs strength and elegance in one commanding design. A brilliant 1.15ctw round lab grown center diamond is elevated in a solid cathedral setting, where the basket walls sweep upward in full, uninterrupted arches from the shank shoulders — no cutouts, no windows, just a confident, enveloping silhouette that lifts the stone with architectural authority. Four flat-top squared talon prongs cap the lab grown diamond at each corner with precision.
The bypass flat-top shank is the design's most dynamic element. One polished rail flows diagonally over the other as it approaches the base of the cathedral setting, creating an asymmetric crossover that softens the boldness of the solid gallery walls with a hint of fluid movement. The flat top surface of the shank adds visual width and presence on the finger, while the mirror-polished finish keeps the entire ring effortlessly sleek.
Available in 10K/14K/18K White, Yellow, or Rose Gold and Platinum.
