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 precision.

Crafted from 10K white gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit, designed for everyday wear without bulk. The setting’s artisan finish reveals subtle handwork in the prongs and gallery, ensuring the stones sit low enough to slip easily beneath gloves or stack alongside other bands.

Each lab-grown diamond offers clarity and brilliance with a smaller environmental footprint, reflecting our commitment to ethical jewelry without compromise.

Ideal for those who appreciate architectural elegance and a statement silhouette, this ring balances boldness with refined wearability. The marquise’s tapered points elongate the finger, while the three-stone layout adds depth and meaning.

Should you need resizing or wish to explore custom stone pairings, our Brooklyn studio welcomes your questions with a pressure-free approach.
