Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of a marquise diamond, casting a slender shadow that seems to stretch beyond the hand. This semi-set solitaire invites you to choose a center stone that echoes that graceful silhouette—6 by 3.5 millimeters of poised brilliance waiting to be framed.

Crafted in warm 18K yellow gold, the mounting’s delicate prongs cradle the stone with a refined balance of security and light exposure. The band’s subtle taper and smooth finish ensure a comfortable fit, designed for everyday wear without fuss. Each piece is meticulously hand-finished in our Williamsburg studio, where precision meets quiet artistry.

Our commitment to lab-grown diamonds means your ring carries clarity and radiance with a lighter environmental footprint, reflecting a modern approach to ethical jewelry.

The marquise shape’s tapered points elongate the finger, lending an elegant, vintage-inspired drama that suits those who appreciate distinctive geometry with a romantic edge. Its low-profile setting pairs well with stacking bands or a wedding ring, while the comfort fit ensures it feels as natural as it looks.

Should you need resizing, our in-house artisans provide careful adjustments to maintain the ring’s integrity and balance.
