Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, dramatic shadow that dances across the hand. This three-stone semi-set engagement ring frames an 8 x 4 mm marquise center with two delicate side stones, each meticulously positioned to enhance its tapered brilliance.

Crafted from 14K white gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit, designed for daily wear without catching or discomfort. The low-profile setting keeps the stones close to the finger, balancing presence with practicality. Each prong is hand-finished to cradle the marquise securely while allowing light to flood the facets.

Our commitment to sustainability is reflected in the lab-grown diamonds chosen for their clarity and ethical origin, reducing environmental impact without compromising radiance.

This ring suits those who appreciate architectural elegance combined with a subtle vintage flair. Its slender shape elongates the finger, while the three-stone design adds narrative depth—ideal for stacking or wearing solo. The semi-set format invites you to select a center stone that resonates personally.

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