Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, confident silhouette across the hand. This three-stone semi-set engagement ring in 14K yellow gold frames a 9 x 4.5 mm marquise center, its sharp geometry softened by the warm glow of the band.

Each element is crafted with precision in our Williamsburg studio: the low-profile setting ensures daily wearability without catching, while the smooth comfort fit embraces the finger with subtle ease. The three-stone arrangement balances modern minimalism with architectural clarity, allowing the marquise’s tapered drama to take center stage.

Our diamonds are lab-grown, offering a transparent origin and a lighter environmental footprint without compromising brilliance or clarity.

This ring suits those who appreciate structured elegance and a design that layers beautifully with other bands or stands strikingly alone. Its streamlined profile fits comfortably under gloves or sleeves, ideal for an active lifestyle.

Should you wish to adjust the fit, resizing is handled delicately in-house to maintain the integrity of the setting and band.
