Lab-Grown Diamond Engagement Ring

Light catches the elongated facets of the emerald-cut diamond, casting a glassy, architectural glow that feels both modern and quietly refined. This semi-set platinum band awaits your choice of a center stone, crafted with a low-profile bezel setting designed to sit close to the finger for everyday wear without catching.

Each ring is meticulously hand-finished in our Williamsburg studio, where the cool weight of platinum is shaped and polished to a smooth comfort fit. The mounting’s clean lines emphasize the emerald shape’s linear elegance, offering a subtle stage for the stone’s clarity and depth.

Our commitment to lab-grown diamonds ensures a clarity and brilliance that honors both the earth and your values, reflecting a sustainable approach without compromise.

Ideal for those who appreciate architectural form and understated luxury, this solitaire mounting pairs effortlessly with stacking bands or stands alone as a statement of quiet confidence. Its low profile makes it glove-friendly and suitable for active daily life.
