All over the world there is a tradition to give names to gem diamonds weighing more than 20 carats. This is true for Russia too. Diamonds get their names in honor of historical events or anniversaries, which coincide with the time of finding; they are also given names of famous people.
The Diamond Fund collection of large gem diamonds is unique and has great scientific value. Large stones are valuable as samples of rare natural formations, the study of which could shed light on the conditions of their growth.
The largest diamond from the collection (342.57 carats) was mined in 1980 at Mir kimberlite pipe and was named "The 26th Congress of the Communist Party of the Soviet Union” in honor of the congress, which was held in 1981.
