Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a poised brilliance that draws the eye along the finger. This semi-set engagement ring foundation in cool platinum offers a sleek, modern-minimal frame designed to highlight a 10 x 5 mm marquise center stone of your choosing.

Crafted with precision in our Williamsburg studio, the platinum band is polished to a soft sheen and engineered for daily wear with a low-profile setting that balances presence and comfort. Accents along the shank add a refined structure without overwhelming the diamond’s distinctive shape, creating a confident yet understated statement.

Each lab-grown diamond we work with reflects a commitment to ethical sourcing and sustainability, offering clarity and sparkle without compromise.

The slender band suits those who appreciate architectural elegance and desire a ring that layers effortlessly with wedding bands or stackable styles. Its streamlined form is glove-friendly and designed to feel light on the hand, ideal for an active lifestyle.

Should you need resizing, our in-studio experts ensure a seamless adjustment tailored to your comfort and fit.
