Lab-Grown Diamond Engagement Ring

The elongated silhouette of a 12 x 6 mm marquise diamond catches the eye with its tapered points, creating a striking balance of drama and elegance. This semi-set solitaire ring in 14K white gold offers a refined foundation, crafted with meticulous artisan techniques in our Williamsburg studio.

The band is hand-finished to a smooth comfort fit, designed to sit low on the finger for everyday wear without catching. Its slender profile complements the marquise’s architectural shape, allowing light to dance along the stone’s facets with vivid clarity. Each setting is inspected closely to ensure secure prongs that cradle the diamond while maintaining an open, airy feel.

Our commitment to sustainability is reflected in the choice of a lab-grown diamond, offering exceptional clarity and brilliance with a lighter environmental footprint. This ring suits those who appreciate a bold yet wearable statement, ideal for stacking or wearing solo with ease.

Should you wish to customize the fit, resizing is available to ensure comfort and longevity. The semi-set design invites you to select a center stone that resonates personally, making the ring uniquely yours.
