Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of an 8 x 6 mm oval diamond, its soft glow tracing the contours of a hand poised to say yes. This three-stone engagement ring, set in cool platinum, balances architectural grace with artisanal precision.

Each diamond is securely nestled in a low-profile setting that emphasizes the stone’s gentle elongation while maintaining everyday wearability. The platinum band is hand-finished in our Williamsburg studio, polished to a subtle sheen that complements the diamonds’ clarity without distraction. Comfort-fit edges ensure the ring feels as natural as it looks, designed for daily life and layered styling.

Crafted exclusively with lab-grown diamonds, this ring reflects a commitment to ethical sourcing and environmental mindfulness, offering brilliance without compromise.

Its slender silhouette suits hands that appreciate refined geometry and a touch of vintage-inspired modernity. The three-stone layout adds dimension without bulk, making it glove-friendly and ideal for stacking alongside wedding bands or delicate bracelets.

Should you need a custom size, resizing is handled expertly in-house to preserve the ring’s integrity and finish.
