Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its pointed ends drawing the eye along a sleek, confident line. This three-stone semi-set ring in 18K white gold frames an 8 x 4 mm marquise center with two delicate side stones, balancing modern minimalism with architectural clarity.

Each band is hand-finished in Williamsburg, Brooklyn, with a low-profile setting that rests close to the finger for everyday ease. The comfort fit shank ensures the ring feels as thoughtful as it looks, while precise prong work secures the stones without excess metal, allowing light to dance freely.

Crafted exclusively for lab-grown diamonds, this design reflects a commitment to ethical jewelry—minimizing environmental impact without compromising brilliance or durability.

Its elongated marquise shape naturally elongates the hand, ideal for those seeking a refined yet distinctive statement. The three-stone layout offers subtle symbolism and versatility, pairing seamlessly with stacking bands or worn solo.

Should you need resizing, our Brooklyn studio handles adjustments with care to maintain the ring’s structural integrity. Typical lead times accommodate custom stone selection and finishing.
