Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a 12 x 6 mm marquise diamond, it reveals a striking balance of tapered drama and refined elegance. This semi-set solitaire ring in 14K rose gold offers a sleek, low-profile mounting designed to sit close to the finger, minimizing snagging while maximizing everyday comfort.

Crafted in Williamsburg, the band is hand-finished to a smooth comfort fit, its warm rose tone complementing the diamond’s fiery brilliance. The prong setting is engineered to secure the stone firmly while allowing ample light to animate the facets, enhancing the marquise’s signature sparkle.

Each lab-grown diamond is ethically sourced, reflecting a commitment to sustainability without compromising clarity or fire. This ring’s streamlined silhouette suits those who appreciate modern geometry with a subtle vintage nod, ideal for stacking or wearing solo.

Resizing is available to ensure a precise fit, and the semi-set design invites you to select a center stone that resonates personally. Whether designed in-studio or online, this piece is made to accompany daily life with quiet confidence.
