Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a graceful, tapered brilliance. This semi-set halo engagement ring foundation in cool platinum invites your choice of a 9 x 4.5 mm center stone, framing it with a delicate halo that amplifies sparkle while maintaining a refined profile.

Crafted in our Williamsburg studio, the platinum band is meticulously shaped for comfort and durability, its low-profile setting designed to sit close to the finger without sacrificing presence. Each curve and prong is hand-finished to ensure smooth edges and secure mounting, reflecting artisan precision in every detail.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and beauty with a smaller environmental footprint.

This ring suits those who appreciate a statement piece that remains practical for daily wear—its slender silhouette complements slender to medium finger shapes and layers effortlessly with wedding bands or stackable rings. The halo setting enhances the marquise’s natural drama without overwhelming delicate hands.

Should you need resizing or prefer a different center stone, our in-studio consultations provide tailored guidance and flexible lead times to bring your vision to life.
