Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set engagement ring frame, crafted in 18K white gold, awaits your choice of a 7 x 3.5 mm center stone to complete its modern-minimal design.

The band’s sleek profile balances subtlety with structure, accented by delicate side stones that enhance the diamond’s clarity and confident geometry. Finished with a smooth comfort fit, it sits close to the finger for everyday wear without catching or bulk.

Each piece is meticulously hand-finished in our Williamsburg studio, where precision meets quiet craftsmanship. The lab-grown diamond option ensures a responsible origin, reflecting a commitment to sustainable luxury without compromise.

Ideal for those who appreciate architectural elegance and a refined silhouette, this mounting complements slender fingers and pairs effortlessly with stackable bands or wedding rings of varied styles.

Should you need resizing or prefer a custom accent arrangement, our Brooklyn studio offers personalized consultations to tailor the ring to your vision.
