Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This 7 x 3.5 mm marquise center stone is set low in a platinum band designed for everyday elegance without compromise.

Crafted in Williamsburg, the ring’s platinum setting offers a secure, low-profile embrace with delicate accent stones that enhance the diamond’s tapered drama. The smooth comfort fit band ensures it sits close to the finger, ideal for stacking or solo wear, while the refined setting minimizes snagging.

Each lab-grown diamond is chosen for clarity and brilliance, reflecting a commitment to sustainable, ethical jewelry without sacrificing radiance. The marquise shape’s distinctive silhouette elongates the finger, flattering a variety of hand sizes with its architectural poise.

Resizing is available to ensure a precise fit, and the ring arrives ready to wear, polished and inspected in-studio. Whether layered with other bands or worn alone, this engagement ring balances bold geometry with subtle craftsmanship.
