Artistry Meets Innovation as Alrosa Automates the Diamond Cutting Process

Russian mining giant Alrosa has announced that its Smolensk-based Kristall cutting facility has successfully implemented high-tech automation across several stages of the diamond cutting process. The move is designed to dramatically increase efficiency while maintaining the precision and artistry associated with the famous “Russian Cut.”

According to Alrosa, automation has reduced the labor intensity of cutting operations by up to 80%, accelerated production timelines and lowered costs — all while preserving the hallmark quality that distinguishes Russian diamonds on the global stage.

The new system begins with advanced scanners that create precise 3D models of each rough diamond, mapping both external and internal structures, including inclusions. Based on these scans, digital cutting plans are generated, offering multiple options to optimize yield and maximize value. Once the plan is selected, the stones undergo automated laser sawing and shaping.

At the final stage, Kristall’s master craftsmen step in. While technology has taken over much of the heavy lifting, artisans still complete the most delicate aspects of polishing and faceting. They are supported by a trio of technological assistants: parameter scanners, real-time polishing quality monitors and navigational devices that ensure perfect facet alignment. The result is a diamond that meets the uncompromising standards of the “Russian Cut.”

More a quality benchmark than a specific shape, the Russian Cut is internationally recognized for its exceptional brilliance, precision and balance of carat weight and sparkle. It reflects a long tradition of Russian gem-cutting artistry, now enhanced by modern innovation.

As the world’s largest producer of rough diamonds by volume, Russia remains a dominant force in the industry. In 2024, the country produced 37.3 million carats, representing roughly 32% of global output and valued at $3.335 billion.
