Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a 6.5 x 6.5 mm square diamond, its facets reflecting a quiet geometry that commands attention without excess. This three-stone semi-set engagement ring foundation invites your choice of center stone, framed by a structured 18K white gold band that balances modern minimalism with architectural clarity.

Crafted in Williamsburg, Brooklyn, the band’s clean lines and precise angles are finished to a smooth comfort fit, designed to sit low on the finger for everyday wear without catching. The setting’s subtle profile complements stacking or solo wear, offering versatility for evolving personal style.

Each lab-grown diamond option embodies ethical clarity, reducing environmental impact while maintaining exceptional brilliance and purity. This ring’s design honors sustainability without compromise.

Ideal for those who appreciate confident structure and understated elegance, the square shape lends a contemporary edge that elongates the finger’s silhouette. The three-stone layout adds dimension and meaning, perfect for marking a layered story.

Resizing is available to ensure a precise fit, and the semi-set nature allows you to select a center stone that resonates personally, with expert guidance from our Brooklyn studio.
