Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of this marquise diamond, casting a slender, graceful shadow across your hand. The 12 x 6 mm center stone is set low in a secure 14K yellow gold band, designed to slip comfortably beneath gloves and everyday wear.

Each ring is meticulously crafted in our Williamsburg studio, where the smooth, polished shank meets a subtle accent setting that enhances the diamond’s tapered drama without adding bulk. The low-profile mounting ensures the ring sits close to the finger, balancing presence with practicality.

Our lab-grown diamonds offer the clarity and brilliance of natural stones with a fraction of the environmental impact, reflecting a commitment to ethical jewelry that feels as good as it looks.

This engagement ring suits those who appreciate architectural elegance paired with a design made for daily life—its comfort fit and streamlined silhouette invite stacking or solo wear with equal ease.

Should you need a custom fit, resizing is handled expertly in-house to maintain the ring’s integrity and finish.
