Malachite is a carbonate mineral often associated with copper ores. As explained by Jeffrey Post, it "grows in layers of tiny crystals, and its colors correlate with different crystal sizes: smaller crystals form light green bands and larger crystals make darker ones."[1] In the late eighteenth and nineteenth centuries, most malachite came from mines in Russia owned by the noble Demidov family, who exploited hardstone quarries and metal deposits on their estates in the remote Ural Mountains. One of the great discoveries in the history of semiprecious stones occurred in the 1820s, when an enormous boulder of malachite weighing about five hundred tons was unearthed in the Urals.[2] A schistose material, malachite is extremely brittle, and only small display objects can be cut from single blocks of this rock. Large objects require a core structure, to which the malachite can be attached in thin pieces. Russian craftsmen perfected a way of utilizing the stone's natural pattern and a precision cutting technique to form a continuing or, on the round body of a vase, an "endless" ornament. This type of veneer, called "Russian mosaic, " looks almost seamless.[3] The Demidovs used the showy appearance of malachite to increase their social status. They filled their palaces and decorated a whole room in one of them with the green stone, inspiring Czar Nicolas I to commission the famous Malachite Room in the Winter Palace in Saint Petersburg.[4] The Metropolitan Museum's vase is modeled on one t
