However, the significant variability of the features of decorative stones, as well as the physical limitations of the sets of material standards, complicates the identification process and reduces the likelihood of obtaining a correct result. Despite the fact that the identification of the petrographic appearance of the material of products and raw materials from decorative rocks by their mineral and chemical composition is a daily task in the activities of expert gemologists, a more accurate identification of decorative stones (for example, determining the origin, place of extraction and / or identification of trademarks ) in the world of gemological science is one of the most difficult problems. The main task of constructing ways for an acceptable solution to the above problems is to abstract, digitally determine the main mineralogical and chemical features of the object of identification and the reference standard, as well as to generalize and standardize the process of solving the problem in such a way that this method can be applied without the use of material standards, replacing the latter. mathematical models ("virtual standard").
