Alrosa’s Crystal plant in Smolensk has introduced automation across crucial stages of diamond cutting, cutting labour requirements by as much as 80% while preserving the renowned precision of the “Russian cut.”
The process starts with advanced scanners creating 3D models of rough diamonds, mapping both internal and external features, including inclusions. These digital models provide several cutting options, enabling experts to choose the one that delivers the greatest value.
From there, the stones are automatically sawn and laser-shaped, after which master cutters at Crystal take over for the final, intricate cutting. Their work is enhanced by tools such as scanners for dimensional checks, real-time polishing quality monitors, and navigators that assist in aligning facets.
Alrosa noted that this integration of cutting-edge automation with expert craftsmanship not only speeds up production but also guarantees exceptional diamond quality.
