Lab-Grown Diamond Engagement Ring

Imagine the quiet moment when light catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc across your hand. This semi-set engagement ring offers a refined foundation in 18K white gold, crafted with a low-profile bezel setting that cradles a 7 x 3.5 mm marquise stone—ready to be chosen and personalized.

The band’s subtle curve and polished finish ensure a comfortable fit for daily wear, while the solitaire design highlights the diamond’s graceful geometry, evoking a sense of poised elegance. Each piece is meticulously hand-finished in our Williamsburg studio, where precision meets a tactile softness that invites touch.

Our commitment to sustainability is reflected in the lab-grown diamond option, offering clarity and brilliance without compromise. This ring suits those who appreciate a slender, elongated shape that visually lengthens the finger and pairs effortlessly with stacking bands or wedding rings.
