Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that dances across the skin. This semi-set halo ring invites you to choose a 7 x 3.5 mm lab-grown marquise stone, its pointed ends lending a graceful drama that elongates the finger with quiet elegance.

Crafted in polished sterling silver, the band offers a cool, luminous backdrop that enhances the halo’s delicate frame. The setting is designed with a low profile, ensuring the ring sits comfortably for daily wear without catching on fabric or gloves. Each piece is meticulously finished by hand in our Williamsburg studio, where every prong and curve is inspected for seamless balance and durability.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, which provide exceptional clarity and brilliance while minimizing environmental impact.

This ring suits those who appreciate refined romance with a modern edge—its slender shape complements slender to medium fingers and pairs beautifully with stackable bands or a simple wedding band. The low-profile setting makes it ideal for an active lifestyle, blending elegance with practicality.
