Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand as a marquise diamond’s tapered silhouette catches the light, offering a quiet drama without excess. This semi-set platinum mounting awaits your choice of a 9 x 4.5 mm marquise center, designed with slender accents that enhance without overpowering.

Crafted in solid platinum, the band features a low-profile setting that sits close to the finger for everyday comfort and resilience. Its streamlined design minimizes snagging, making it ideal for those who value both elegance and practicality. Each piece is meticulously finished and inspected in our Williamsburg studio, ensuring a smooth, comfort-fit experience.

Our lab-grown diamonds provide the same optical brilliance and clarity as mined stones, with a significantly reduced environmental footprint.

This mounting suits hands that appreciate refined geometry and a sleek silhouette, pairing well with stackable bands or worn solo for understated sophistication. The low profile also makes it glove-friendly and easy to wear daily.

Should you need resizing, our in-house artisans handle adjustments with care to maintain the ring’s integrity and comfort.
