About the Company

The history of ALROSA dates back to 1954, when geologist Larisa Popugaeva discovered Zarnitsa, the first kimberlite pipe and the first primary deposit of diamonds in the Soviet Union. The discovery paved the way for industrial diamond mining in the country.  

A year later, the Mir kimberlite pipe was discovered by the Amakinskaya expedition led by Yu. Khabardin, while another team led by V. Shchukin discovered the Udachnaya pipe.

The discovery of diamonds in Western Yakutia created a true sensation in the world because it had been a general belief that there were no commercial deposits of this precious mineral in the country.

In January 1957, a decision was made to begin mining and production operations on alluvial and ore deposits in the diamond-rich region of Yakutia. To manage the facilities construction and subsequent operations, the Yakutalmaz group of companies was established with headquarters in Mirny. V.I. Tikhonov was appointed its first chief executive, and L.V. Zhelyabin was appointed chief geologist. Six months later, Processing Plant No.1, a pilot industrial processing facility, was commissioned. In its first washing season alone, the plant produced more diamonds than had all Urals region mines combined during the preceding ten years. Two years later, the Soviet Union sold the first shipment of Yakut diamonds on the world market.

Subsequent years saw the discovery of new kimberlite pipes (Aikhal, Internatsionalnaya, and Yubileynaya).

In 1992 the Diamonds of Russia-Sakha joint stock company was founded, which in 1998 was renamed ALROSA Company Limited. The company became the legal successor of its constituent enterprises, as well as organizations and units of the Yakutalmaz research and production association (the leading diamond mining company of the former Soviet Union), and some divisions of the Russian Federation Ministry of Finance's Committee for Precious Metals and Gem Stones, which were responsible for the grading, presale preparation and selling of diamonds, and the exporting arm Almazyuvelirexport.  

The company obtained control over the exploration, mining, marketing and sales of diamonds on the domestic and world markets with the aim of ensuring the efficient functioning and development of Russia’s rough and polished diamond producing industry, and its position on world diamond markets.
