Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate, tapered sparkle that dances with every movement. This 12 x 6 mm center stone is cradled in a 14K yellow gold setting, where artisan hands have shaped and polished the band to a smooth, comfortable fit that rests lightly on the finger.

The low-profile mounting features subtle accent stones that enhance the marquise’s dramatic point without overwhelming its refined geometry. Each facet is carefully inspected in our Williamsburg studio to ensure clarity and brilliance, while the warm gold band is finished with a soft sheen that invites daily wear.

Crafted from lab-grown diamond, this ring reflects a commitment to ethical sourcing and sustainability, offering a clear alternative to traditional mining without compromising on beauty or durability.

Designed for those who appreciate a statement piece that remains practical, its slender profile slips easily beneath gloves and stacks gracefully with other bands. The marquise shape elongates the finger, lending an elegant, architectural presence that suits a confident, modern wearer.

Should you need a custom adjustment, resizing is handled expertly in-house to maintain the integrity of the design and comfort fit.
