Lab-Grown Diamond Engagement Ring

Under the soft glow of Williamsburg’s evening light, the marquise diamond catches every glance with its tapered silhouette, evoking a quiet drama that elongates the hand. This 9 x 4.5 mm lab-grown marquise is nestled within a delicate halo of pavé-set stones, amplifying its brilliance while maintaining a refined profile.

Crafted from 14K white gold, the band is shaped and polished in our Brooklyn studio to a smooth comfort fit, designed for daily wear without compromising elegance. The halo setting balances sparkle with subtlety, ensuring the ring sits low enough to slip easily beneath gloves or stack alongside other bands.

Each diamond is ethically sourced through lab-grown technology, reducing environmental impact without sacrificing clarity or fire. The ring’s artisan finish reflects careful hand inspection and expert setting, hallmarks of our in-studio craftsmanship.

Ideal for those who appreciate architectural grace paired with wearable design, this ring complements slender fingers and suits a modern aesthetic that values both statement and subtlety. Resizing is available to ensure a precise fit, with typical lead times communicated transparently.
