The main charitable event of the year was held in Yekaterinburg. One of the lots of the charity auction, the culminating event of the Assembly, was a diamond brooch – the cipher of Catherine the Great.

Since 1762, the precious adornment was a badge of distinction and special position at the court for the imperial ladies-in-waiting. In 2018, the official custodian of the honorary symbol, the Peterhof State Museum-Reserve, transferred the right to reproduce the historical code to the CHAMOVSKIKH jewelry house. The craftsmen exactly repeated the historical decoration – a gold brooch set with 123 diamonds, which is topped with a stylized imperial crown.

With a starting price of 400,000 rubles, the diamond brooch was sold for 4.08 million.
