Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a delicate shadow that dances along the warm blush of 18K rose gold. This semi-set solitaire frame awaits your choice of an 8 x 4 mm marquise center, designed to showcase the stone’s tapered drama and elegant elongation.

Hand-forged in our Williamsburg studio, the band’s subtle curve and smooth polish reflect hours of artisan attention. The low-profile setting ensures the ring sits close to the finger, offering a comfortable fit that slips easily beneath gloves or alongside stackable bands. Each piece undergoes meticulous finishing and inspection to meet exacting standards.

Crafted with a lab-grown diamond in mind, this ring embodies a commitment to ethical jewelry—minimizing environmental impact without compromising brilliance or clarity.

Ideal for those who appreciate refined geometry and a ring that balances statement with everyday wearability, this design complements slender to medium finger shapes, enhancing natural hand lines.
