Lab-Grown Diamond Engagement Ring

When light catches the elongated points of a marquise diamond, it creates a striking silhouette that both elongates the finger and commands quiet attention. This three-stone semi-set ring in 18K white gold offers a poised foundation for a 7 x 3.5 mm marquise center, designed with a low-profile setting that nestles close to the hand for everyday ease.

Crafted in Williamsburg, Brooklyn, the band is meticulously shaped for comfort fit, ensuring it slides on smoothly without catching. The three-stone arrangement balances visual drama with subtlety, while the polished white gold surface reflects light softly, enhancing the diamond’s architectural facets. Each mounting is finished by hand and inspected for precision, ready to showcase your chosen center stone.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint. This ring suits those who appreciate refined geometry and a design that integrates seamlessly with daily life—stackable with other bands or worn solo for a statement that’s both modern and enduring.

Should you need resizing or have questions about care, our Brooklyn studio provides personalized guidance to ensure your ring fits perfectly and maintains its luster over time.
