Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it carves a striking, elegant line across the finger—an emblem of refined confidence. This semi-set engagement ring in 10K white gold offers a sleek foundation tailored for a 9 x 4.5 mm marquise center, framed by delicate accent stones that enhance its architectural clarity without distraction.

Crafted in Williamsburg, the band’s low-profile design ensures a comfortable fit for daily wear, with a smooth finish that feels seamless against the skin. The setting’s precision allows the diamond’s pointed ends to remain secure while maximizing brilliance and minimizing snagging.

Each lab-grown diamond is chosen for its exceptional clarity and ethical origin, reflecting a commitment to sustainability without compromise. The cool white gold complements the stone’s icy fire, creating a modern-minimalist aesthetic that balances structure with subtlety.

Ideal for those who appreciate clean lines and confident geometry, this ring pairs effortlessly with stackable bands or stands alone as a statement of quiet strength. Its refined silhouette suits slender to medium finger shapes, enhancing elongation without overwhelming.

Resizing is available to ensure a perfect fit, with careful attention to preserving the setting’s integrity. Typical lead times accommodate custom adjustments without rush.
