Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, luminous shadow that seems to stretch beyond the finger. This semi-set halo engagement ring in 14K yellow gold frames a 6 x 3.5 mm marquise center with a delicate circle of pavé stones, enhancing its architectural grace without overwhelming its modern-minimal silhouette.

Crafted in Williamsburg, the band’s smooth finish and low-profile setting ensure a comfortable fit for daily wear, while the halo adds subtle brilliance that complements the diamond’s tapered drama. Each piece is meticulously inspected to meet exacting standards, reflecting the studio’s commitment to refined structure and clarity.

Our lab-grown diamonds offer the same optical purity as mined stones with a significantly reduced environmental footprint, aligning with a quiet ethos of sustainability.

This ring suits those who appreciate confident geometry and a sleek profile, ideal for stacking or wearing solo with ease. The semi-set design invites you to select a marquise diamond that resonates personally, making the ring uniquely yours.

Resizing is available to ensure the perfect fit, and our Brooklyn studio welcomes you to explore custom options in person or through our online design experience.
