Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its tapered points drawing the eye along the length of your finger, framed by a delicate halo that amplifies its fiery silhouette. This semi-set engagement ring foundation in 18K white gold awaits your choice of a 7 x 3.5 mm marquise center, designed to showcase the stone’s elegant elongation and spirited light play.

Crafted in our Williamsburg studio, the band features a refined low-profile setting that balances presence with everyday comfort. The artisan finish reveals hand-polished surfaces and secure prongs, ensuring the halo nestles closely around your chosen diamond without excess height—ideal for stacking or glove-friendly wear. Each piece undergoes meticulous inspection to meet exacting standards of fit and finish.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, offering clarity and brilliance with a reduced environmental footprint.

This ring suits those who appreciate architectural grace paired with subtle sparkle, especially flattering on slender fingers or anyone seeking a distinctive yet wearable statement. The semi-set design invites you to select a marquise diamond that resonates with your personal story.

Resizing is straightforward, handled expertly in-studio to maintain the integrity of the setting and comfort fit.
