Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a delicate shadow that dances like whispered promises. This semi-set halo engagement ring in 14K white gold frames a center stone measuring 15 by 7.5 millimeters, its tapered silhouette lending an elegant drama that elongates the finger with quiet confidence.

Crafted in Williamsburg, the band is polished to a soft sheen, designed with a low-profile setting that nestles close to the hand for everyday wear. The halo of smaller stones encircles the marquise, enhancing its brilliance without overpowering its distinctive shape. Each prong is meticulously finished to secure the stone while maintaining a refined, delicate appearance.

Our commitment to sustainability is reflected in the use of a lab-grown diamond, offering clarity and sparkle with a lighter environmental footprint. This ring’s comfort fit and slender profile make it ideal for stacking alongside wedding bands or wearing solo with grace.

Should you wish to adjust the size, resizing is available to ensure a perfect fit without compromising the integrity of the design. Lead times for completion typically align with our Brooklyn studio’s careful handcrafting process.
