Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the hand’s natural lines. This semi-set halo ring foundation in warm 14K rose gold offers a delicate frame for a 12 x 6 mm center stone, designed to amplify the diamond’s dramatic sparkle.

Each band is hand-forged in our Williamsburg studio, where the rose gold is carefully polished to a soft, glowing finish. The halo setting is crafted to sit low against the finger, balancing presence with everyday comfort. Its subtle curve and secure prong work ensure the ring feels as natural as it looks.

Our commitment to lab-grown diamonds means this piece carries a clear ethical edge—sustainably sourced with the same optical brilliance as mined stones, but with a lighter environmental footprint.

The elongated marquise shape flatters slender fingers and lends an elegant elongation to the hand, while the halo setting adds a vintage-inspired shimmer without bulk. This ring suits those who appreciate a refined yet distinctive profile, and its low-profile design pairs effortlessly with wedding bands or stackable rings.

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