Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of this marquise diamond, it casts a subtle, tapered sparkle that draws the eye along the finger’s natural line. The 12 by 6 mm center stone is framed by a delicate halo of smaller diamonds, enhancing its dramatic shape without adding bulk.

Crafted in solid platinum, the ring offers a low-profile halo setting designed for everyday wear. The smooth comfort-fit band and secure prong setting ensure the diamond sits close to the hand, minimizing snagging and maximizing ease for daily life. Each piece is meticulously finished and inspected in our Williamsburg studio, where precision meets quiet durability.

Our lab-grown diamonds provide the same optical brilliance and clarity as mined stones, with a significantly reduced environmental footprint.

This engagement ring suits those who appreciate architectural elegance paired with practical design—ideal for hands that favor a slender, elongating shape and a ring that layers effortlessly with wedding bands or stackable rings. Its low profile makes it glove-friendly and unobtrusive for active lifestyles.

Resizing is available to ensure a perfect fit, crafted with care to maintain the integrity of the halo setting.
