Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This three-stone semi-set engagement ring features a 7 x 3.5 mm marquise center, its faceted brilliance framed by two delicately sculpted side stones.

Crafted in warm 18K yellow gold, the band is hand-finished in our Williamsburg studio to a smooth comfort fit that sits low enough for everyday wear without sacrificing presence. The prong setting secures the stones while allowing light to flood every angle, enhancing the marquise’s signature tapered drama.

Each diamond is lab-grown, offering a clarity and sparkle indistinguishable from mined stones, with a fraction of the environmental impact. This ring’s design balances bold geometry with artisan subtlety, ideal for those who appreciate refined craftsmanship and ethical jewelry.

Its slender profile and moderate center size make it well-suited for hands that favor elegance without excess bulk, and the three-stone layout invites thoughtful stacking or pairing with a wedding band. The semi-set format allows you to select a center diamond that perfectly matches your vision.

Resizing is available to ensure a precise fit, and our Brooklyn studio welcomes you to explore this design in person or collaborate on a custom variation online.
