Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow that dances across the skin. This three-stone semi-set engagement ring frames a 9 x 4.5 mm marquise center with two gently curved side stones, each chosen to enhance the signature tapered drama of the shape.

Handcrafted in warm 18K rose gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit that feels like a natural extension of the hand. The low-profile setting balances presence with everyday wearability, allowing the stones to sit close to the finger without catching. Each prong is meticulously finished to cradle the marquise securely while showcasing its glassy, elongated elegance.

Our commitment to sustainability is reflected in the use of lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint.

This design suits those who appreciate refined geometry and a ring that layers effortlessly with wedding bands or stackable styles. The slender marquise shape visually elongates the finger, while the three-stone layout adds a narrative depth, symbolizing past, present, and future.

Should you need resizing, our in-house artisans ensure a seamless adjustment without compromising the ring’s integrity or finish.
