Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow across the hand. This semi-set five-stone engagement ring in 14K yellow gold frames a 6 x 3.5 mm marquise center with delicate side stones that echo its graceful taper.

Each band is hand-shaped and polished in our Williamsburg studio, ensuring a smooth comfort fit that settles low against the finger for everyday wear. The prong setting secures the stones while allowing light to dance freely through their facets, enhancing the marquise’s signature brilliance and subtle drama.

Crafted with lab-grown diamonds, this ring reflects a commitment to ethical jewelry—minimizing environmental impact without compromising clarity or fire.

Its slender profile and gentle curve suit those who appreciate refined elegance and a ring that layers effortlessly with wedding bands or stackable favorites. The narrow width complements smaller hands and offers glove-friendly wear.

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