The inclusion of diamants is a diagnostic sign of the naturality of the stone in examinations of diamants

Abstract

The article covers the issue of diagnostic characteristics of diamonds, examples of inclusions are given that are characteristic of natural stones and their synthetic counterparts. The subject of improvements in the quali ty characteristics of stones, which is directly related to their cost, is touched upon. There are several diamond criteria that gemologists take into account when evaluating the quality of gemstones, such as color, clarity, carat weight and cut quality. In total, these criteria are the basis of the diamond classifi cation, which is called the 4Cs. The higher the 4Cs, the more expensive the stone. Clarity as one of the criteria is used to evaluate the beauty and value of diamonds. Different degrees of clarity affect the price of a diamond. To gether they are called clarity features or inclusions. Not only do they help appraisers distinguish between synthetic and natural diamonds, they also allow you to assess the quality of the diamond. Moreover, the types of inter nal defects in diamonds that are analyzed as their diagnostic features are given in the article. The article shows how important it is to conduct a pro fessional microscopic examination during the diamond analysis. Thus, in depth examination of stones under a microscope is an integral component in diagnosing diamonds. Due to the lower price of synthetic stones, some dishonest entrepreneurs pass off synthetic stones as natural. Therefore, it is important to understand the questions that arise when diagnosing stones, namely: what are the stones by origin, how are they different, how to diag nose them.
