Lab-Grown Diamond Engagement Ring

When light catches the gentle curves of a 5 x 5 mm heart-shaped diamond, it reveals a quiet intimacy—an emblem of affection carved in precise facets. This semi-set halo ring invites your choice of center stone, framed by a delicate halo that amplifies brilliance while maintaining a refined silhouette.

Crafted from 18K white gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit, designed for everyday wear without catching or bulk. The low-profile halo setting balances sparkle with subtlety, making it an ideal companion for stacking or solo elegance.

Each piece reflects our commitment to ethical jewelry: lab-grown diamonds offer exceptional clarity and sustainability without compromise. This ring’s artisan finish ensures every angle is inspected and perfected by hand before it reaches you.

Its graceful heart shape lends a romantic softness, flattering a range of finger sizes and shapes with a modern yet tender geometry. The semi-set design allows you to select a stone that resonates personally, making the ring uniquely yours.

Should you need resizing or advice on stone selection, our Brooklyn studio offers personalized guidance with thoughtful care and prompt turnaround.
