Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it carves a striking beam that draws the eye along the finger’s length. This semi-set solitaire ring offers a refined foundation for a 9 x 4.5 mm marquise stone, designed to showcase its tapered drama without distraction.

Crafted in 18K white gold, the mounting features a low-profile setting that sits close to the skin, minimizing snagging and maximizing comfort for daily wear. The band’s smooth finish and subtle taper ensure a balanced feel, while the secure prongs cradle the stone with precision, reflecting careful inspection and expert finishing in our Williamsburg studio.

Each lab-grown diamond option embodies clarity and sustainability, aligning with a modern ethical approach to fine jewelry.

This solitaire setting suits those who appreciate architectural elegance and want a ring that complements slender fingers or pairs seamlessly with stacking bands. Its modest height and comfort fit make it glove-friendly and ideal for an active lifestyle.

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