Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow that draws the eye along the finger’s natural line. This semi-set solitaire mounting, crafted from warm 18K yellow gold, offers a refined foundation for a 6 x 3.5 mm marquise center stone, ready to showcase your chosen gem.

The band’s low-profile design ensures the ring sits close to the hand, minimizing snagging while maintaining an elegant presence. Expertly finished with a smooth comfort fit, it balances durability with everyday ease, making it a reliable companion for daily wear. The setting’s precise prongs cradle the stone securely, allowing maximum light to enhance the diamond’s signature pointed ends.

Each piece is handcrafted in our Williamsburg studio, reflecting a commitment to ethical jewelry through the exclusive use of lab-grown diamonds—offering clarity and sustainability without compromise. The semi-set format invites you to select a marquise diamond that resonates personally, ensuring a truly bespoke expression.

Designed for those who appreciate architectural grace and subtle sophistication, this ring complements slender to medium finger shapes and layers seamlessly with stackable bands. Its streamlined profile also fits comfortably under gloves or sleeves, ideal for an active lifestyle.
