Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate dance of light across the hand. This semi-set engagement ring invites your choice of a 10 x 5 mm center stone, framed by four smaller companions that echo its graceful taper.

Crafted in 18K white gold, the band’s subtle sheen complements the marquise’s distinctive shape—a blend of vintage allure and modern refinement. The five-stone setting balances presence with wearability, designed with a low-profile bezel that rests comfortably for daily wear without catching.

Each piece is finished by hand in our Williamsburg studio, where precision meets quiet artistry. The lab-grown diamond option ensures clarity and brilliance with a mindful footprint, reflecting an ethical commitment without compromise.

Ideal for those who appreciate a ring that elongates the finger and pairs effortlessly with stacking bands or a wedding band. Its comfort fit and modest height make it glove-friendly and suited for everyday life.

Should you wish to adjust sizing or explore center stone options, our Brooklyn studio offers personalized consultations to guide your custom design journey.
