Lab-Grown Diamond Engagement Ring

Imagine the moment light catches a marquise diamond’s elongated silhouette, casting a subtle, tapered sparkle that feels both bold and refined. This semi-set halo engagement ring foundation in 14K white gold frames a 9 x 4.5 mm marquise center with a crisp, modern-minimal edge, designed to amplify the diamond’s architectural grace.

Crafted with precision in our Williamsburg studio, the band’s smooth low-profile setting ensures daily wearability without catching, while the halo setting—ready to embrace your chosen stone—adds a structured brilliance that balances clarity with confident geometry. Each piece is hand-finished and carefully inspected to meet exacting standards.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, offering clarity and sustainability without compromise.

The slender band suits those who appreciate a sleek silhouette, ideal for stacking or wearing solo with a glove-friendly comfort fit. The marquise shape naturally elongates the finger, making it a striking choice for hands seeking a blend of drama and elegance.

Should you need resizing, our in-house team ensures a seamless adjustment to maintain the ring’s integrity and comfort.
