Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger’s natural line. This semi-set three-stone engagement ring in 18K white gold offers a refined foundation for a 7 x 3.5 mm marquise center, ready to be paired with carefully chosen side stones that enhance its sculptural elegance.

Handcrafted in our Williamsburg studio, the band is forged from solid 18K white gold, polished to a soft sheen that complements the diamond’s crisp facets. The setting balances secure prongs with a low-profile design, ensuring daily wearability without sacrificing the ring’s architectural grace. Each curve and angle is inspected meticulously, reflecting artisan precision and a commitment to lasting craftsmanship.

Our diamonds are lab-grown, providing a clarity and brilliance equal to mined stones while aligning with sustainable practices that respect the environment.

The slender band and subtle height make this ring ideal for those who appreciate a sleek silhouette that layers effortlessly with wedding bands or stackable rings. Its comfort fit ensures it feels as natural as it looks, whether worn solo or combined.

Should you wish to adjust the fit, resizing is available through our Brooklyn studio with care tailored to preserve the ring’s integrity.
