Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, its tapered points drawing the eye along the hand with subtle drama. This semi-set halo ring foundation in 18K yellow gold is crafted in our Williamsburg studio, where each curve of the band is hand-finished to a smooth, comfort fit that wears effortlessly every day.

The halo setting, designed to surround your chosen 8 x 4 mm marquise stone, enhances brilliance while maintaining a low profile that slips easily beneath gloves or sleeves. The warm glow of the yellow gold complements the diamond’s fiery facets, a balance of artisan precision and thoughtful design.

Our commitment to lab-grown diamonds ensures clarity and sparkle without compromise, reflecting a sustainable approach to fine jewelry. The ring’s shape and size suit those who appreciate a statement piece that remains refined and wearable, ideal for stacking or solo wear.

Resizing is available to ensure a perfect fit, with careful attention to preserving the ring’s structural integrity. Lead times vary depending on stone selection, but we guide you through every step with transparency and care.
