The purpose of the work is to create a system of research operations on classifying, sorting and evaluation of rough diamonds to monitor its quality and supervise the movement across the customs border of Ukraine. Research methods - literary and analytical. Results of work: It is shown that there is no single methodological approach to the classification and sorting of rough diamonds in the world. Each sorting organization takes as a basis the commercial classification of the international corporation De Beers, which it simplifies and modifies according to its own tasks. The scheme for sorting rough diamonds, which is being developed for introduction into SGCU, is planned to combine the main methodological approaches existing in the Russian Federation and Belgium using the criteria for evaluating cut diamonds according to SGCU Technical Specifications. A glossary of rough diamonds has been developed for the purpose of unifying the applied nomenclature. It is shown that knowledge of equipment and devices, as well as the processes used in the processing of rough diamonds are necessary components for predicting yield, which is the basis for the correct classification of rough diamonds. The creation of a photo library of virtual rough diamond comparison samples according to various classification criteria has been started. Sphere of use - Gemological examination of diamonds for customs purposes. There are no plans to introduce the results of work at this stage.
