Lab-Grown Diamond Engagement Ring

Imagine the subtle gleam of a marquise diamond catching light with every gesture—its elongated silhouette lending a refined drama to the hand. This semi-set platinum mounting awaits your choice of an 8 x 4 mm marquise center, designed with a low-profile setting that nestles close to the finger for everyday ease.

Crafted in Williamsburg, the band’s smooth finish and secure prong architecture ensure comfort and durability without excess height, making it glove-friendly and ideal for stacking. The platinum’s cool sheen complements the marquise’s tapered points, while the mounting’s precise angles reflect expert finishing and inspection.

Each ring embraces lab-grown clarity, reflecting a commitment to sustainable luxury without compromise. Its streamlined silhouette suits those who favor a refined, modern aesthetic with practical wearability.

Resizing is straightforward, handled delicately in-studio to maintain structural integrity. Lead times are transparent, with personalized consultations available to guide your selection.
