Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate sparkle that dances with every movement. This three-stone semi-set ring features a 7 x 3.5 mm marquise center, poised to frame your chosen stones with refined balance.

Crafted from 14K white gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit, ensuring it rests lightly against the skin. The low-profile setting keeps the stones close to the hand, ideal for daily wear without catching. Each prong is meticulously finished by hand, securing your center stone while allowing maximum light to pass through the facets.

Our lab-grown diamonds offer the same optical brilliance as mined stones with a smaller environmental footprint, reflecting a commitment to ethical jewelry that honors both beauty and responsibility.

The three-stone design suits those who appreciate symbolic layering—past, present, and future—while the marquise shape elegantly elongates the finger. Its slender form pairs effortlessly with stacking bands or stands strikingly alone.
