Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of an 8 x 4 mm marquise diamond, casting a slender, luminous shadow across your hand. This semi-set engagement ring invites you to select a center stone that balances dramatic taper with graceful sparkle.

Crafted from warm 18K yellow gold, the band is shaped and polished in our Williamsburg studio, where artisan hands refine each curve to a smooth comfort fit. The low-profile setting holds accent stones with delicate precision, enhancing the marquise’s tapered drama without adding bulk.

Our diamonds are lab-grown, offering clarity and brilliance with a mindful approach to sustainability and ethical sourcing.

Designed for those who appreciate a ring that feels as natural as it looks, this setting suits slender to medium finger sizes and layers beautifully with stackable bands or wedding rings. Its modest height ensures ease of wear with gloves or daily tasks.

Should you wish to adjust the fit, resizing is handled expertly in-house to preserve the ring’s integrity and finish.
