Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a delicate arc. This three-stone semi-set ring features a 6 x 3.5 mm marquise center, poised to be paired with your choice of side stones, all cradled in warm 14K rose gold that contrasts softly with the cool white gold shank.

Each band is hand-finished in our Williamsburg studio, where the artisan’s touch ensures a low-profile setting that sits comfortably for daily wear. The subtle curve of the shank and precise prong work balance security with elegance, while the smooth interior offers a comfort fit that feels natural on the finger.

Crafted exclusively with lab-grown diamonds, this ring reflects a commitment to sustainability without compromising on clarity or brilliance.

Its slender shape and moderate center size suit hands that appreciate refined geometry and a graceful elongation, making it ideal for stacking or wearing solo. The semi-set design invites personalization, allowing you to select side stones that echo your story.

Should you need resizing, our Brooklyn studio handles adjustments with care, ensuring the ring maintains its structural integrity and finish.
