Lab-Grown Diamond Engagement Ring

Under the soft glow of Brooklyn’s evening light, the sharp geometry of the Asscher cut catches the eye—its step-cut facets revealing a quiet architectural elegance. This 5 x 5 mm lab-grown diamond rests within a delicate halo, amplifying its vintage-inspired clarity while maintaining a modern silhouette.

Crafted in cool platinum, the ring’s low-profile setting ensures a comfortable fit that slides easily beneath a sleeve or glove. Each facet is meticulously polished in our Williamsburg studio, where precision meets a tactile sense of balance and weight. The halo setting is hand-set to enhance brilliance without overwhelming the diamond’s distinctive shape.

Our commitment to sustainability is reflected in the lab-grown clarity of the center stone, offering an ethical alternative without compromise on sparkle or structure.

Designed for those who appreciate refined geometry and subtle romance, this ring complements slender to medium finger sizes and layers gracefully with other bands for a personalized stack.

Should you need a custom fit, resizing is available through our Brooklyn studio with care tailored to preserve the ring’s integrity.
