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 Three Stone Round Brilliant Lab Grown Diamond Engagement Ring is the ultimate expression of past, present, and future — reimagined at the pinnacle of luxury. A breathtaking 2.50ctw round lab grown center diamond is flanked by two equally stunning large round brilliant lab grown side stones in a shared 4-prong bead setting, creating a magnificent trilogy of lab grown diamonds that commands attention from every angle for an extraordinary 5.04 total carat weight.
Pavé-set round lab grown diamonds adorn the gallery wall beneath the three main stones and continue along both shoulders of the band, adding a layer of brilliance that makes the ring sparkle from every perspective. The three stones cascade in a beautiful height graduation — center elevated highest, side stones slightly lower — creating a dynamic, dimensional silhouette. The plain polished lower shank balances the diamond-rich upper profile with clean elegance.
Available in 10K/14K/18K White, Yellow, or Rose Gold and Platinum.
