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 Double Halo Lab Grown Diamond Engagement Ring builds visual impact through concentric geometry. A 1.15ctw round brilliant lab grown diamond sits at the heart of a double cushion-shaped halo — two distinct rings of round lab grown diamonds radiating outward in overlapping waves of light.
The pavé shank graduates from larger stones at the shoulders down to smaller diamonds at the base, running the full length of both sides — continuously diamond-set from gallery to base.
Available in 10K/14K/18K White, Yellow, or Rose Gold and Platinum.
