Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, graceful shadow across the hand. This semi-set halo engagement ring in 14K yellow gold frames a 12 x 6 mm marquise center with a delicate circle of pavé stones, enhancing its signature tapered drama without adding bulk.

Crafted for everyday wear, the low-profile setting keeps the diamond close to the finger, reducing snagging while maintaining brilliance. The warm glow of yellow gold complements the stone’s fiery facets, finished with a smooth comfort fit band that feels natural from morning coffee to evening strolls. Each piece is meticulously inspected in our Williamsburg studio to ensure precise prong tension and polished edges.

Our lab-grown diamonds offer the same optical and chemical properties as mined stones, with a smaller environmental footprint and traceable origins.

This ring suits those who appreciate architectural elegance paired with practical design—ideal for hands that favor slender silhouettes and a setting that layers well with wedding bands or stackable rings. Its modest height fits comfortably under gloves or sleeves.

Resizing is available to ensure a perfect fit, with typical lead times of 4–6 weeks from design approval.
