Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a delicate, tapered glow that seems to stretch the fingers with quiet elegance. This three-stone semi-set ring features a 7 x 3.5 mm marquise center, poised to frame your chosen lab-grown diamond with two smaller side stones, all cradled in 10K white gold.

Each band is hand-shaped in our Williamsburg studio, polished to a satin-smooth finish that rests comfortably against the skin. The low-profile setting ensures the ring wears gracefully beneath gloves or daily tasks, while the three-stone design offers a balanced silhouette that complements slender and average finger shapes alike.

Crafted with lab-grown diamonds, this piece reflects a commitment to ethical jewelry—minimizing environmental impact without compromising brilliance or clarity.

Its slender shank and secure prong setting make it ideal for stacking or pairing with a wedding band, offering versatility for evolving personal style. The semi-set format invites you to select a center stone that resonates most deeply, a personal touch in every detail.

Should you need resizing, our in-studio artisans ensure a precise fit without sacrificing structural integrity. Typical lead times accommodate careful customization, honoring the craft behind each ring.
