Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This three-stone semi-set ring, crafted in cool 14K white gold, frames a 6 x 3 mm marquise center with two delicate side stones, offering a balanced silhouette that feels both refined and dynamic.

Each band is hand-shaped and polished in our Williamsburg studio, ensuring a smooth comfort fit that sits low enough for everyday wear without sacrificing presence. The prong setting secures the stones while allowing light to flood their facets, enhancing the marquise’s signature brilliance and elongating effect.

Our diamonds are lab-grown, chosen for their clarity and ethical provenance, reflecting a commitment to sustainability without compromise on sparkle.

This design suits those who appreciate architectural elegance with a hint of vintage allure, especially flattering on slender fingers or for stacking alongside a wedding band. Its low-profile setting slips easily under gloves and rings comfortably for daily life.

Should you wish to customize the center stone or adjust sizing, our Brooklyn studio offers personalized consultations with attentive craftsmanship and timely turnaround.
