Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette that feels both bold and intimate. This three-stone semi-set ring features a 12 x 6 mm marquise center, poised to frame your chosen stones with a delicate balance of presence and grace.

Crafted from warm 10K yellow gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit, designed for everyday wear without catching or discomfort. The three-stone setting offers a low profile that nestles close to the finger, ideal for stacking or pairing with a wedding band.

Each piece is finished by hand, inspected under magnification to ensure precise prong alignment and a secure cradle for your center diamond. The semi-set design invites you to select a lab-grown marquise diamond, combining ethical clarity with the artisan’s touch.

Lab-grown diamonds offer a sustainable alternative, reducing environmental impact while maintaining the brilliance and fire of mined stones.

This ring suits those who appreciate architectural elegance with a hint of vintage drama, especially flattering on longer fingers or those who prefer a statement piece that remains refined and wearable.
