Lab-Grown Diamond Engagement Ring

When light catches the elongated points of a marquise diamond, it creates a striking silhouette that feels both bold and refined. This three-stone semi-set ring features a 9 x 4.5 mm marquise center, poised to frame your chosen stones with an 18K white gold band that balances strength and subtlety.

Each band is meticulously crafted in our Williamsburg studio, where the cool sheen of 18K white gold is hand-finished to a smooth, comfort fit that rests lightly against the skin. The low-profile setting ensures everyday wearability without sacrificing the architectural drama of the marquise shape.

Our diamonds are lab-grown, offering a clarity and brilliance that honors sustainable practices without compromise. This ring’s design suits those who appreciate a statement piece that remains elegant and practical—ideal for stacking or wearing solo with gloves or bare hands.

Should you need adjustments, resizing is handled expertly in-house to maintain the integrity of the artisan finish. Lead times are transparent and tailored to your custom design journey.
