Unperfect Sphere 18k Diamond Ring — a quiet ode to imperfection from a perfectionist inpatient.

This ring, crafted in 18k yellow gold, embodies CINCO’s philosophy of finding beauty in irregular form. Four 3.5mm diamonds (totaling 0.64ct) are bezel-set within a sculptural, organic silhouette — where every curve feels instinctive rather than precise.

Its surface plays with light and shadow, each diamond reflecting a slightly different rhythm, echoing the individuality of imperfection. The result is a bold yet intimate piece that celebrates contrast — structure and softness, control and release, perfection and its deliberate fracture.

The Unperfect Sphere Ring is not only jewelry — it’s a reminder that harmony can live inside asymmetry, and that true beauty rarely needs symmetry to be complete.
