Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette across the hand. This semi-set three-stone engagement ring offers a poised foundation for a 7 x 3.5 mm marquise center, framed by two delicate side stones that enhance its architectural grace.

Crafted in cool, enduring platinum, the mounting is shaped with a low-profile setting that nestles close to the finger, balancing presence with everyday comfort. Each prong is meticulously hand-finished in our Williamsburg studio, ensuring secure hold and refined edges that glide smoothly beneath gloves or stacked bands.

The lab-grown marquise diamond at the heart of this design reflects a commitment to ethical jewelry, offering clarity and brilliance without compromise to the environment.

Its slender shape naturally elongates the finger, ideal for those who appreciate a blend of bold geometry and subtle elegance. The three-stone layout invites personalization, whether you choose matching side stones or contrasting accents to express your story.

Resizing is available to ensure a precise fit, with careful attention to maintaining the ring’s structural integrity and comfort fit.
