The Gokhran of Russia sold 3,505 carats of polished diamonds from the State Fund of Russia for $1.25 million at its auction on February 27.

In 2024-2026, the Ministry of Finance of the Russian Federation plans to sell precious metals and precious stones from state reserves worth 1 billion rubles annually. The focus of these sales will mostly be on low-value and low-liquidity products such as -sized rough and polished diamonds, mass-produced jewelry made from precious metals and precious stones, as well as other types of similar valuables that are not of interest for long-term storage in the State Fund of Russia.

Meanwhile, on March 19, Gokhran will hold the first auction of non-special size diamonds for 2024. The auction will include lots with an initial value of $9.66 million and a total weight of 205,000 carats.
