Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, graceful shadow across the hand. This semi-set engagement ring invites you to choose a center stone that balances bold geometry with delicate refinement.

Crafted from warm 10K yellow gold, the band is shaped and polished in our Williamsburg studio to a smooth, comfortable fit that wears effortlessly every day. The low-profile setting cradles the marquise stone securely while allowing light to flood its pointed ends, enhancing the gem’s signature brilliance and dramatic taper.

Each ring reflects our commitment to ethical jewelry: the center stone is lab-grown, offering clarity and sparkle with a lighter environmental footprint. The artisan finish reveals subtle handwork, from the precise prongs to the softly rounded shank, designed to complement slender or more robust fingers alike.

Ideal for those who appreciate a striking solitaire that pairs well with stacking bands or stands confidently alone. The semi-set format means you can select an 8 x 4 mm marquise diamond that suits your personal style and budget, with resizing available to ensure a perfect fit.
