Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a marquise diamond catching light with every gesture, its tapered points echoing a quiet elegance. This semi-set engagement ring in platinum offers a refined foundation for a 6 x 3.5 mm marquise center, designed to sit low against the finger for everyday grace.

Crafted in Williamsburg, the platinum band is polished to a smooth finish, engineered for comfort with a low-profile setting that minimizes snagging. Accents frame the mounting subtly, enhancing the stone’s distinctive shape without overwhelming its architectural silhouette.

Each lab-grown diamond is selected for clarity and brilliance, reflecting a commitment to sustainable luxury without compromise. The ring’s streamlined design suits hands that appreciate understated sophistication and pairs effortlessly with stackable bands or wedding sets.

Resizing is available to ensure a precise fit, and the semi-set style invites you to choose a center stone that resonates personally. Whether designed in-studio or online, this piece balances technical assurance with the intimate craft of Brooklyn’s fine-jewelry scene.
