Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette that gently elongates the finger. This semi-set solitaire ring offers a refined foundation in 18K white gold, crafted with a low-profile setting that balances presence with everyday comfort.

The band’s smooth contour and secure prong setting ensure the diamond sits close to the hand, minimizing snagging while maximizing wearability. Each piece is meticulously finished and inspected in our Williamsburg studio, where precision meets subtlety in every curve and facet.

Our commitment to lab-grown diamonds means this marquise center carries the clarity and brilliance of natural stones with a smaller environmental footprint. The ethical choice is seamlessly integrated into a design built for daily life.

Ideal for those who appreciate architectural elegance paired with practical design, this ring suits slender to medium finger shapes and layers effortlessly with stacking bands or wedding rings. Its comfort fit and low profile make it glove-friendly and resilient for active wear.

Should you need resizing, our Brooklyn studio offers personalized adjustments to ensure a perfect fit without compromising the ring’s integrity.
