Lab-Grown Diamond Engagement Ring

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

Crafted in 18K white gold, the mounting balances durability with a sleek silhouette, its halo setting meticulously finished to enhance sparkle without bulk. The band’s subtle taper and smooth interior ensure a comfort fit that pairs seamlessly with other stackable rings or a wedding band.

Each piece reflects Haejin Jewelry’s commitment to ethical jewelry, featuring lab-grown diamonds that combine brilliance with sustainability. The low-profile design suits active lifestyles and glove-friendly wear, making it a practical choice for daily life in Williamsburg and beyond.
