The Sistema Ring embodies Parts of Four’s architectural approach to jewelry—precise, weighted, and uncompromising. Crafted in Dirty 18K Gold Skin, the ring begins as sterling silver, acid-treated to disrupt the surface before being fused with a layer of 18K yellow gold. The result is a finish that feels raw yet elevated, where abrasion and refinement coexist.
With its wide band and substantial presence, this ring is designed as a statement of structure and material rather than ornament—timeless, genderless, and deliberately imperfect.
