Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow across the hand. This three-stone semi-set engagement ring features a 12 x 6 mm marquise center, poised to frame your chosen stones with quiet precision.

Crafted from 10K white gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit, designed for daily wear without bulk. The setting’s low profile balances presence with practicality, allowing the marquise’s tapered points to shine while minimizing snagging.

Each ring is hand-finished and inspected by artisans who specialize in bespoke fine jewelry, ensuring the prongs cradle your stones securely while maintaining an elegant, refined silhouette.

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

This design suits those who appreciate architectural grace and a statement that elongates the finger, pairing well with slender stacking bands or worn solo for understated drama.

Should you need resizing or prefer a custom stone selection, our Brooklyn studio offers personalized consultations to tailor the ring to your vision.
