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 Oval Three Stone Lab Grown Diamond Engagement Ring pairs a 1.20ctw oval-cut lab grown center diamond with two matched round brilliant lab grown side stones. The oval center is held by four prongs, its silhouette framed symmetrically by the flanking rounds.
Beneath the oval center, the gallery opens into a decorative floral form — petal-shaped claw extensions curve downward from the basket, lifting the stone gracefully and creating an airy negative space.
Available in 10K/14K/18K White, Yellow, or Rose Gold and Platinum.
