Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of an 8 x 4 mm marquise diamond, its tapered points drawing the eye along a delicate halo of shimmering pavé. This engagement ring, set in warm 14K yellow gold, balances bold geometry with artisan precision, each prong hand-shaped to cradle the stone securely while allowing light to flood every facet.

The band’s smooth finish and modest profile ensure comfort for daily wear, while the halo setting amplifies the diamond’s natural brilliance without adding bulk. Crafted in our Williamsburg studio, the ring undergoes meticulous inspection to meet exacting standards of polish and symmetry.

Our lab-grown diamonds offer a clarity and sparkle comparable to mined stones, with a fraction of the environmental impact—reflecting a commitment to ethical jewelry that honors both beauty and responsibility.

Designed for those who appreciate a statement piece that remains refined, this ring suits slender to medium finger sizes and pairs effortlessly with stacking bands or a wedding band of similar width. Its low-profile setting slips easily beneath gloves or sleeves, making it a practical choice for everyday life.

Should you need a custom fit, resizing is available through our Brooklyn studio with care to preserve the ring’s integrity.
