Alrosa’s subsidiary, Crystal, at its Smolensk facility, has integrated automation into key stages of diamond cutting, reducing labour intensity by up to 80% while preserving the precision of the renowned “Russian cut.”

The upgraded process begins with advanced machines scanning rough diamonds to create detailed 3D models, mapping both internal and external structures, including inclusions. These models generate multiple cutting scenarios, enabling experts to select the approach that maximises value.

Following the planning stage, diamonds are automatically sawn and laser-shaped. The final stage combines human craftsmanship with technological support: master cutters use scanners to check parameters, real-time polishing quality testers, and navigational tools to ensure precise facet alignment.

Alrosa said the integration of automation with expert human oversight not only accelerates production but also upholds the company’s strict standards of diamond quality, blending efficiency with artistry.
