Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a square diamond, its precise facets reflecting a quiet geometry that feels both modern and intimate. This solitaire semi-set invites your personal selection of a 3.75 x 3.75 mm center stone, poised to become the heart of a ring that balances strength with subtlety.

Crafted in a fixed two-tone combination of warm 18k yellow and 18k yellow and platinum and cool 18k yellow and platinum, the band offers a tactile contrast—smooth 18k yellow and platinum prongs cradle the diamond, while the 18k yellow and 18k yellow and platinum shank curves gently beneath, creating a harmonious interplay of metals. The low-profile setting ensures the ring sits comfortably for daily wear, its streamlined silhouette slipping easily beneath gloves or alongside other bands.

Each piece is meticulously finished in our Williamsburg studio, where expert hands polish and inspect every detail to meet exacting standards. The lab-grown diamond option reflects a commitment to ethical jewelry, offering clarity and brilliance without compromise.

Designed for those who appreciate architectural elegance with a romantic edge, this ring suits slender to medium finger sizes and pairs beautifully with stackable bands or as a statement solitaire. Resizing is available to ensure a perfect fit, crafted with care to maintain the integrity of the two-tone design.
