Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a confident, architectural gleam. This semi-set halo engagement ring foundation in 10K white gold frames an 8 x 4 mm center stone with a delicate circle of pavé, designed to amplify brilliance without overwhelming the finger.

Crafted in Williamsburg, the band’s sleek profile balances modern minimalism with structural clarity. The low-set halo and smooth shank ensure daily wearability, slipping comfortably beneath gloves or alongside stackable bands. Each piece is meticulously finished by hand, inspected for precision and comfort.

Our commitment to sustainability is reflected in the choice of a lab-grown diamond, offering exceptional clarity and ethical provenance without compromise.

This ring suits those who appreciate refined geometry and subtle statement—ideal for slender fingers or anyone seeking a distinctive yet wearable silhouette. The semi-set design invites you to select a center stone that resonates personally, making the ring uniquely yours.

Resizing is straightforward, handled in-studio with care to maintain the band’s integrity and comfort fit.
