Lab-Grown Diamond Engagement Ring

When light catches the sharp edges of a square diamond, it reveals a quiet geometry that feels both modern and intimate. This semi-set solitaire invites you to choose a center stone that measures 3.75 by 3.75 millimeters, offering a poised balance between presence and subtlety.

Crafted in warm 14K rose gold, the band’s smooth polish complements the diamond’s crisp lines, while the low-profile setting ensures the ring sits comfortably for daily wear. Each piece is meticulously finished in our Williamsburg studio, where precision meets a gentle hand to create a refined silhouette that slips easily beneath gloves or alongside other bands.

Our diamonds are lab-grown, reflecting a commitment to ethical jewelry that honors both clarity and conscience without compromise.

This solitaire suits those who appreciate architectural simplicity with a romantic edge—ideal for hands that favor clean shapes and a comfortable fit that invites everyday connection.
