Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand as a marquise diamond, measuring 9 by 4.5 millimeters, catches the light with its tapered brilliance. This semi-set engagement ring foundation in 14K white gold offers a low-profile silhouette designed for everyday grace and ease.

Crafted in Williamsburg, the band’s sleek form balances strength with comfort, ensuring a secure fit that slips smoothly beneath gloves or stacks effortlessly with other bands. The setting’s precise engineering allows your chosen marquise stone to sit close to the finger, minimizing snagging while maximizing sparkle.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that deliver clarity and fire without compromise. The cool white gold finish is carefully polished to a satin sheen, enhancing the diamond’s crisp edges and architectural shape.

Ideal for those who appreciate refined geometry and a confident yet understated presence, this mounting supports a marquise center that elongates the finger with elegant drama. Its adaptable design suits a variety of hand sizes and personal styles.
