Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a large cushion diamond, its gentle glow poised to become the centerpiece of a three-stone story. This semi-set engagement ring in 14K white gold awaits your choice of an 11 x 11 mm cushion-cut diamond, known for its plush, vintage-inspired shimmer that balances warmth with refined geometry.

Crafted in our Williamsburg studio, the band’s smooth, low-profile shank is designed for everyday grace, offering a comfortable fit that slips easily beneath gloves or alongside stackable bands. The three-stone setting is meticulously hand-finished, with secure prongs that cradle each gem while maximizing light’s dance across their facets.

Each diamond is lab-grown, reflecting a commitment to ethical jewelry that reduces environmental impact without sacrificing brilliance or clarity.

This ring suits those who appreciate a statement piece that remains wearable—its balanced proportions and classic white gold tone complement a range of personal styles and hand shapes.
