Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with quiet drama. This semi-set three-stone ring foundation in 18K white gold offers a sculptural frame for a 6 x 3 mm center stone, designed to balance presence with everyday grace.

Each band is hand-formed in our Williamsburg studio, polished to a satiny finish that feels smooth against the skin. The low-profile setting ensures the ring sits comfortably beneath gloves or sleeves, while the three-stone arrangement adds subtle dimension without bulk. Our artisans inspect every curve and prong for precision, ensuring a secure yet refined mount.

Crafted with a lab-grown diamond center in mind, this piece reflects a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

Its slender shank and tapered points suit hands that appreciate architectural elegance, pairing effortlessly with stackable bands or worn solo for a statement that is both modern and personal.

Should you need resizing, our in-house team offers careful adjustments to maintain the ring’s integrity and comfort fit.
