Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a marquise diamond catching light with every turn of the hand, framed by a delicate halo that enhances its tapered drama. This semi-set engagement ring foundation in 18K white gold offers a low-profile silhouette designed for daily wear, balancing elegance with practicality.

Crafted in Williamsburg, Brooklyn, the band is meticulously finished to a smooth comfort fit, ensuring it sits close to the finger without catching. The halo setting is engineered to amplify the 5 x 3 mm marquise center’s brilliance while maintaining a secure, streamlined structure.

Each piece features a lab-grown diamond foundation, reflecting a commitment to ethical jewelry that minimizes environmental impact without compromising on clarity or sparkle.

Ideal for those who appreciate architectural shapes with a refined presence, this mounting suits slender to medium finger sizes and pairs effortlessly with stackable bands or wedding rings. Its modest height makes it glove-friendly and unobtrusive for everyday life.
