Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the finger with subtle drama. This solitaire semi-set invites you to select a 10 x 5 mm center stone, ready to become the centerpiece of a finely crafted engagement ring.

Hand-forged in 14K white gold, the mounting features a low-profile setting designed for everyday wear without catching or discomfort. The band’s smooth finish and balanced weight ensure a comfortable fit, while the secure prong structure highlights the marquise’s distinctive shape without overwhelming it.

Each ring is crafted in our Williamsburg studio with lab-grown diamonds, reflecting a commitment to ethical sourcing and sustainability without compromise on brilliance or clarity.

Ideal for those who appreciate architectural elegance and a sleek silhouette, this setting pairs well with slender hands and complements stacking bands or wedding rings with ease. Its modest height and refined craftsmanship make it glove-friendly and practical for daily life.

Should you need resizing or prefer a custom finish, our Brooklyn studio offers personalized consultations to tailor the ring to your exact preferences and timeline.
