Purity characterizes the presence or absence of inclusions in a synthetic diamond. It determines the transparency, origin of internal and external defects, their color, size and location in the stone. The fewer defects, the more expensive the diamond. Typically, a 10-fold magnifying glass is used to determine purity.


Most (white) diamonds used in jewelry range in color from colorless to slightly yellow or brown. This is also the most important feature of the diamond, as it is the color we see most of all with the human eye. There is a Russian and international classification of diamonds by color. The Russian classification includes two sections: for small stones (up to 0.29 ct) - 7 colors, for large stones (from 0.30 ct) - 9 colors. The international classification denotes colors in letters from D--Y and does not depend on the size of the stone.

The weight of the diamond created in the laboratory is expressed in carats (Ct).One carat weighs 1/5 grams and is rounded to the hundredths.

The weight of diamonds is measured in carats, abbreviated ct. The word "carat" itself comes from the name of the seeds of the Karaib tree, which served in ancient times as a reference weight. But already in 1907 the weight was established, on the basis of a certain standard - a metric carat equal to 200 mg. One carat corresponds to 0.2 grams. The scale of the carat division consists of 100 units. The cost of a diamond is calculated based on the price per carat. The higher the weight of the diamond with the same parameters, the higher its cost.
