Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it carves a slender beam that dances across the hand—an intimate gesture of refined drama. This semi-set engagement ring invites you to select a centerpiece measuring 13 by 6 millimeters, its pointed ends echoing a quiet elegance framed by a delicate halo.

Crafted from warm 14K yellow gold, the band is shaped for everyday grace, its smooth finish and low-profile setting designed to slip comfortably beneath gloves or stack alongside cherished bands. The halo setting enhances the marquise’s natural brilliance, surrounding it with a subtle glow that amplifies sparkle without overwhelming the finger.

Each piece is meticulously finished in our Williamsburg studio, where expert hands polish and inspect every curve to ensure a seamless fit and enduring wearability. The semi-set foundation allows for a personalized selection of a lab-grown diamond, chosen for clarity and ethical provenance.

Lab-grown diamonds offer a conscious choice, reducing environmental impact while delivering the same optical fire and structural integrity as mined stones.

Ideal for those who appreciate a blend of vintage-inspired shape with modern comfort, this ring suits slender to medium finger profiles and complements a variety of personal styles, from minimalist to layered.
