Abstract. The necessity to move from subjective parameters for evaluating the quality of colored stones to objective ones is discussed. An automated hardware and software complex based on the methods of technical vision and image processing and intended for determining in quantitative form such indicators for assessing the quality of colored stones as "size", "color", and "purity" is developed. A description of the developed complex is presented. On the example of beryllium raw materials, the possibilities of quantitative evaluation, packaging and certification of analyzed samples of colored stones are shown. The proposed technical solution can be used by mining and jewelry companies, markets and auctions, gemological centers, and state authorities.
Keywords: colored stones, raw materials, quality assessment, hardware-software complex, certification, color, puri-ty, image processing
