Lab-Grown Diamond Engagement Ring

The elongated silhouette of the 12 x 6 mm marquise diamond draws the eye with its tapered points, offering a striking balance of drama and refinement. This three-stone semi-set ring in 14K yellow gold frames the center stone with two smaller side diamonds, creating a structured yet modern-minimal composition that feels both confident and clear in design.

Crafted in Williamsburg, the band is smoothly finished for comfort, its low-profile setting designed to sit close to the finger without catching—ideal for daily wear. Each prong is meticulously shaped to secure the marquise’s delicate points while maintaining an open gallery that allows light to flood the stone, enhancing its signature brilliance.

Our commitment to sustainability is reflected in the use of a lab-grown diamond, offering the clarity and sparkle of mined stones with a lighter environmental footprint.

The ring’s slender shank and balanced proportions suit hands that appreciate architectural elegance and those who favor stackable styles or a subtle statement piece. Its semi-set nature invites you to select a center stone that matches your personal vision, making this ring uniquely yours.
