Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a delicate, tapered glow that seems to stretch the fingers with quiet drama. This three-stone semi-set ring features a 6 x 3 mm marquise center, poised to frame your choice of lab-grown diamond with precision and grace.

Crafted from 10K yellow gold, the band is shaped for comfort with a subtle curve that sits close to the finger, ideal for daily wear. Each prong is hand-finished in our Williamsburg studio, ensuring a secure yet elegant hold that highlights the diamond’s signature silhouette without excess height.

Our commitment to sustainability is reflected in the lab-grown diamond option, offering clarity and brilliance with a lighter environmental footprint. This ring’s low-profile setting makes it glove-friendly and easy to stack alongside wedding bands or delicate bracelets.

Designed for those who appreciate refined geometry and artisanal detail, the marquise shape elongates the hand while the three-stone arrangement adds a narrative of past, present, and future. Resizing is available to ensure a perfect fit, crafted with the same care as the original design.
