The present report of Research.Techart is dedicated to granite and marble markets. In the course of work the following information was analyzed: Moscow and Saint Petersburg companies' activities and the main processes going on in the present moment on natural stone market. The research was conducted in order to enhance data included in the previous versions of natural stone market reports executed in 2004 - 2009. Natural stone is an ambiguous material for the Russian market. During the imperial period of Russian history a lot of administrative buildings and cultural objects were constructed with the use of granite and marble. However the traditions of processing and using stone were completely lost during Soviet times. In that period construction was supposed to be cheap, that is why stone lining was used only for administrative buildings' decoration. All products made of natural stone were funded, even gravestones were sold only to those who had a special permission. The same situation was also typical for raw materials, processing tools and equipment. In the USSR granite and marble were extracted by means of explosive method. It wasn't possible to use open-cut mining, that is why the excavated stone blocks often had microfissures. Today this technology remains widely spread in Russia. This in turn negatively affects consumer characteristics of stone. For example, there is a limitation on using facing tile made of granite and marble extracted by means of this method. Stone market was liberalized in 90es, after the transition of the state economy to a new system of management. First of all, it affected extracting companies, which started managing assortment and price policy on their own account. The class of trading companies gradually appeared on the market. Today it is transforming into the class of industrial and commercial enterprises. Thus it can be presumed that natural stone is a relatively new type of finishing material, not only for private but also for corporate consumers.
