Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette that draws the eye along the finger’s natural line. This semi-set three-stone engagement ring foundation in warm 10K yellow gold invites your choice of a 10 x 5 mm marquise center, flanked by two smaller stones to balance its architectural grace.

Each band is meticulously crafted in our Williamsburg studio, shaped for a comfortable fit that sits low against the hand without sacrificing presence. The smooth polish and subtle tapering ensure it layers effortlessly with wedding bands or stackable rings, while the secure prong setting promises daily wearability with ease.

Our commitment to sustainability shines through the exclusive use of lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint.

Ideal for those who appreciate a blend of vintage-inspired drama and modern craftsmanship, this ring suits slender to medium finger shapes, enhancing elongation and elegance. Its low-profile design slips easily under gloves or sleeves, making it a practical choice for everyday life.
