Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of a 9 x 7 mm emerald cut diamond, casting a serene, glassy shimmer that feels both architectural and intimate. This semi-set engagement ring foundation, crafted from warm 18K yellow gold, invites your choice of a lab-grown emerald cut center stone, designed to sit low and secure for everyday grace.

Each band is hand-shaped in our Williamsburg studio, its smooth finish and subtle taper ensuring a comfortable fit that slides easily beneath gloves or alongside stackable rings. The setting’s clean lines echo the emerald’s step-cut geometry, emphasizing clarity and light rather than sparkle alone.

Our commitment to sustainability is reflected in the lab-grown diamond option, offering a conscious alternative without compromise on brilliance or integrity.

Ideal for those who appreciate refined craftsmanship and a modern silhouette, this ring suits slender to medium finger sizes, balancing presence with wearability.

Should you need resizing or prefer a custom metal weight, our Brooklyn atelier handles adjustments with care and precision.
