The properties of colored stones, technological operations for the manufacture of products from them are described. The necessary information on the arrangement and operation of equipment, tools, accessories and auxiliary materials used in the processing of colored stone is given. The widespread use of diamond tools in stone processing is the result of a lot of work done over the years by our researchers, manufacturers who have developed and introduced into the industry a new progressive tool and improved technology for processing the most labor-intensive processes, such as cutting, drilling, shaping products and polishing. Currently, work on the complex mechanization of the processes of processing hard rocks of colored stone continues. The mechanization of processing processes creates ample opportunities for creativity for stone cutting, master fashion designer and artist, freeing them from unproductive and heavy manual labor. For a stone cutter to work successfully, a craftsman and an artist of decorative and applied art must not only have artistic training, but also know a special technology.
