The metric system of jewelry business was firstwas proposed more than a hundred years ago in Paris, whereas in Russia carats were used in 1922. Prior to this, different equivalents of carat were used in the world, measured in grams - while its shares were expressed in successive degrees rather than in decimals. In ancient times, the grains of some plants were used to determine the weight of stones, for example, the Mediterranean inhabitants measured it using acacia seeds, each of which is equal to 1 carat. This method was also used by the Greeks and Romans who made gold coins "solidus", weighing 24 seeds of acacia.

Europeans as a measure of carat weightused barley grains. Some experts believe that in connection with the entry of eastern gemstones to Europe, a plant whose seeds originally served as a basis for measuring their weight, it is necessary to search precisely in the East. In the modern world, the measure of the weight of carat is 0.2 g and is the world-recognized unit for measuring the mass of precious stones and, in particular, diamonds.

Today carat is used not only as a jewelrymeasure of weight - it also acts as a unit of measure of volume or area. In Egypt, carats measure the measure of the surface, where one given unit is 175,035 square meters. Also, carats are used to measure the purity of matter, for example, gold, which in pure form corresponds to 24 carats. In terms of thousandths of shares, 18-carat gold corresponds to the standard 750-th test.

The weight of pearls and diamonds is measured inmetric carats. So, if there are several precious stones in one piece of jewelry, their total weight will be denoted by the abbreviation "ct TW". Jewelers can measure the mass of stones with an accuracy of 0.01 carats, since the scale of the carat measurement is divided into 100 units. At the same time, different precious stones having the same weight can differ in size and density, and also have a different price associated with the quality of the cut, the shade of the stone and its purity. However, the price of jewelry products usually increases depending on the karat mass of the diamond, as large stones are very rare.
