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 three-stone ring foundation in warm 14K yellow gold invites your choice of a 6 x 3 mm center stone, ready to become a personal emblem of commitment.

Each band is shaped and polished in our Williamsburg studio, where the artisan’s touch ensures a smooth comfort fit that sits low against the finger. The three-stone setting balances presence with subtlety, designed for everyday wear without catching or discomfort.

Our lab-grown diamonds offer the clarity and brilliance of mined stones with a reduced environmental footprint, reflecting a quiet commitment to ethical jewelry.

This ring suits those who appreciate refined geometry and a vintage-inspired silhouette, especially flattering on slender fingers or when stacked alongside delicate bands. Its low-profile setting makes it glove-friendly and ideal for daily life.

Should you need resizing, our in-house jewelers provide precise adjustments to ensure a perfect fit without compromising the ring’s integrity.
