Lab-Grown Diamond Engagement Ring

Imagine the quiet confidence of a square diamond catching light with architectural precision, framed by a halo that amplifies its geometric clarity. This semi-set engagement ring foundation invites your choice of a 4.5 x 4.5 mm square center stone, designed to sit low against the finger for everyday ease.

Crafted in 10K white gold, the mounting balances durability with refined comfort, featuring a halo setting that enhances brilliance without adding bulk. The band’s subtle profile ensures it layers seamlessly with wedding bands or stackable rings, while its smooth finish minimizes snagging.

Each piece is meticulously inspected in our Williamsburg studio, where expert hands polish and secure every prong to meet exacting standards. The lab-grown diamond option offers a clear, sustainable alternative, reflecting our commitment to ethical jewelry without compromise.

Ideal for those who appreciate modern geometry and a streamlined silhouette, this ring suits a variety of hand shapes and lifestyles, especially those seeking a low-profile setting that wears comfortably beneath gloves or daily activity.
