From Origin to Perfection: A New Standard in Diamond Calibration 

In haute joaillerie and horology, precision is not a detail; it is the keystone upon which everything depends. Every stone must perform with absolute consistency. Achieving this reliably requires more than cutting expertise — it requires control over the entire process. 

From its Antwerp atelier, MAC Cutting Works operates a fully integrated and traceable supply chain through the Diarough Group. Rough is uniquely sourced, manufactured and tracked within a single pipeline. This continuity provides a rare level of control, with complete visibility from origin through to the finished stone. It’s an end-to-end service designed to meet both the provenance requirements and the exacting quality standards of the world’s leading watch and jewelry maisons.  

As an expert in baguette, tapered, carré and step-cut diamonds, MAC Cutting Works specializes in the most technically demanding forms of cutting. Across layouts and pairs, taille sur œuvre and taille sur plan, each stone is shaped with intent, aligned to the strictest high-jewelry standards, and finished by hands that understand precision at the micron level. 

When production reliability, origin traceability, and technical mastery matter most, MAC Cutting Works offers a clear proposition: Complete traceability. Absolute precision. 

Led by Arnaud Tolkowsky and Joffrey Suchowolski, MAC Cutting Works brings together generations of expertise at the highest level of diamond craftsmanship. 

MAC Cutting Works: Where origin is known. Where precision is everything.
