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 Floral Six-Prong Solitaire Lab Grown Diamond Engagement Ring combines two beautifully distinctive design details in one elegant solitaire. A brilliant 1.20ctw round lab grown center diamond is held by six prongs whose bases form a delicate fleur-de-lis / floral petal gallery — a six-petal flower collar that cradles the stone with organic, romantic elegance and is fully revealed from the side.
The wide comfort-fit dome shank is the perfect companion — its rounded, domed profile feels luxuriously comfortable on the finger and creates a bold, substantial presence that is both modern and wearable. Together, the decorative floral setting and the comfort-fit band create a ring that is visually distinctive yet timelessly classic.
Available in 10K/14K/18K White, Yellow, or Rose Gold and Platinum.
