Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette that seems to stretch beyond the finger. This three-stone semi-set ring features a 7 x 3.5 mm marquise center, poised to frame your chosen stone with two delicate side gems, all cradled in cool 14K white gold.

Each band is hand-shaped in our Williamsburg studio, polished to a satin finish that balances subtle sheen with everyday wearability. The low-profile setting ensures the ring sits comfortably beneath gloves or sleeves, while the gentle curve of the shank offers a natural fit for daily life. Our artisans inspect every angle, securing the mounting with precision to highlight the marquise’s signature taper and brilliance.

Crafted with a lab-grown diamond center in mind, this ring reflects a commitment to ethical jewelry—minimizing environmental impact without compromising clarity or fire.

Its slender silhouette suits hands that appreciate refined geometry and those who favor stackable bands or minimalist styles. The semi-set design invites your personal choice of center stone, making it a thoughtful foundation for custom design in Brooklyn.

Resizing is available to ensure a tailored fit, with typical lead times reflecting our handcrafted process.
