Small Russian box set with malachite, 19th. Small metal and bronze box, completely covered with malachite of Russian origin (except for the underside), the purity of the malachite used and the quality of the workmanship (especially the edges of the corners) suggests a work of the Imperial Lapidary Manufacture of Kolyvan in Siberia of the 19th century. An example of the archetype of Russian refinement, this box was made using the Russian mosaic technique (or Russian school of Florentine mosaic), by veneering thin strips of stone. Beautiful work. There is a key and lock mechanism inside, plated on the inside and invisible to the inside view (it however requires to be serviced for a perfect closure).
