The face of stone. About the natural beauty of Ural gemstones, about the unparalleled beauty of pieces and jewellery made by Russian master jewellers. Malachite was used in the furnishing of the lounge room at the Winter Palace in St. Petersburg, which is why it is called the Malachite Room. Also featured are malachite items made using the complex technique of Russian mosaic. This semi-precious stone became widely used by craftsmen after the discovery of huge malachite deposits in the Demidov mines in the Urals.
