Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger like a whispered secret. This semi-set three-stone ring foundation in 10K white gold awaits your choice of a 6 x 3.5 mm center stone, ready to frame your story with artisan precision.

Crafted in our Williamsburg studio, the band’s sleek profile balances strength with subtlety, designed for daily wear without catching or discomfort. Each prong is hand-finished to cradle the stone securely while allowing maximum light to animate the marquise’s distinctive brilliance and graceful shape.

Our commitment to lab-grown diamonds ensures clarity and sparkle with a lighter environmental footprint, reflecting a modern approach to ethical jewelry.

The low-profile setting suits slender fingers and complements stacking with wedding bands or delicate accent rings. Its comfort fit invites everyday wear, while the three-stone layout offers a narrative of past, present, and future.

Should you need resizing, our in-house artisans provide careful adjustments to maintain balance and integrity without delay.
