Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, graceful shadow that dances across the skin. This three-stone semi-set engagement ring frames a 10 x 5 mm marquise center with two delicate side stones, each carefully positioned to enhance the stone’s tapered drama.

Crafted from warm 18K rose gold, the band is hand-finished in our Williamsburg studio, its subtle sheen complementing the diamond’s glassy brilliance. The low-profile setting ensures the ring sits comfortably for daily wear, while the artisan’s attention to detail is evident in the smooth edges and secure prongs that cradle each gem.

Our diamonds are lab-grown, offering a clarity and sparkle indistinguishable from mined stones, with a commitment to sustainability that quietly honors the earth.

Designed for those who appreciate refined geometry and a touch of vintage allure, this ring’s slender shape elongates the finger and pairs effortlessly with stacking bands or a wedding band. Its comfort fit and modest height make it glove-friendly and suited to an active lifestyle.

Should you wish to adjust the size, resizing is available with care to preserve the integrity of the setting and metal finish.
