     It is used to determine the value of a diamond stone by color, clarity, cut quality, and weight (carat). A person who is far from jewelry art is unlikely to find out how close the new acquisition is to perfection. But everyone can determine the cost of a diamond, because the main thing is to know what is measured in carats and the weight of 1 carat. Karlie Kloss smiles in diamond earrings 

 Technically, the process itself can be divided into several stages: evaluating the quality of the cut. Round or oval stones from 17 to 57 faces are in great demand. Weight of the stone. Color - from colorless to brown.  

    Here, jewelers do not give precise characteristics. As a rule, the epithets "saturated", "barely perceptible", "almost invisible", etc. are used. Cleanliness – the presence of chips, defects, cracks, etc.         Only then is the true value of a particular stone determined. What is a carat? It is not known why the carat is a measure of precious stones. It is assumed that in ancient times, barley grains or acacia seeds Ceratonia siliqua were used to determine the weight.  

    But at the beginning of the XX century, the international Committee of weights and measures legalized this unit of measurement of the weight of precious nuggets. Now you can answer what a 1-carat diamond looks like – the size of the cross-section of its circumference is 0.64 cm, the weight is 0.2 g, it has 57 faces and a high degree of ray reflectivity. 

    Hence, all diamonds are classified as follows: the category of large include diamonds weighing 1 carat and higher; medium diamonds weigh up to 0.99 carats; stones weighing less than 0.29 carats are considered small; the remaining stones are called diamond dust. What is the carat value of a diamond?     We define carats of Gold earrings with diamonds, SL; gold ring with diamonds, SL (prices on links)     Large diamonds are rare and almost never on sale. Nuggets of large size and weight can only be seen at auctions. 

    Diamonds of 25 units and higher are very rare guests, they are assigned their own names. Round-cut stones, in turn, are classified as follows: those with perfect processing quality belong to category A. those with very good processing quality belong to category B. Good processing quality is assigned to category B. cut diamonds of average quality belong to category G. The higher this indicator, the brighter the brilliance of the diamond. 

    However, in small stones, this is almost not noticeable. Each cut diamond is subject to certification.     Finished stones are listed on the stock exchange, and from now on the price is determined by the pricing policy of the Diamond exchange. It is simply impossible to buy a stone cheaper than the price indicated in the exchange listing. Prices per unit weight of a diamond are the same all over the world.     At the beginning of the XX century, a stone weighing 3,106. 75 carats was found in one of the South African diamond deposits, called Cullinan.  

    Initially, it had parameters of 100x65x50 mm, but because it had defects, it was split into small stones. How to determine the carat of a diamond? There are several ways to determine the carat of the diamond: the weighting; formula; with the help of special tables. Each method defines a carat with some degree of accuracy.  

    The weight of small stones is estimated by weighing. Special microweights are used for this purpose.     The accuracy of weighing diamonds is determined up to a thousandth of a fraction. In the same way, you can determine a diamond of 3 carats, 1 carat, or the weight of medium stones. Today, the market value of a 1-carat diamond of the highest quality reaches 20 thousand dollars. To determine the price of a gem, multiply the cost per unit of measure by its weight.

    How can I use the formula? To determine the weight of diamonds, it is necessary that they are not fixed in the jewelry.  

    Then a special Tavernier formula is used to find out its weight:

 m = (d 2) x h x 0.0061,  

    where m is the weight of the stone, h is the height, and d is the diameter. The error in such calculations is up to 10% or more.

     How do I find out how many carats in diamonds in mm from the table? Usually we meet with diamonds already encrusted in the decoration. It is not possible to remove the stones from the frame, so the carat value is determined approximately. At the same time, the high price of diamonds sometimes does not depend on this indicator. It is caused by their rarity, the play of color, which is unique to natural stones.  

    What is the carat value of a diamond? We define carats of Gold earrings with diamonds, SL;  

    So, what is a carat and how to determine how many carats are in a 3 mm stone (diamond)? 

    To do this, measure the diameter and then follow the table. According to it, establishes the ratio of the diameter and weight of the stone: the stone is the carat, equal to 0.1 if it is in a diameter of 3 mm, its other name "the national diamond", which cost an average of 10 000 rubles; the diamond weighs 0.3 carats in size 4.3 mm; measurement of the stone of 0.5 corresponds to a size of 5.15 mm, the value of the stone has reached 180 000 the same comparative characteristics; the diamond 1 carat 6.5 mm, the value of this instance may reach half a million rubles; comply with 7.4 mm weight 1.5 carats;  

    The weight of a 2-carat diamond corresponds to the size of an 8.8 mm stone; a 3-carat diamond is 9.4 mm in diameter. Here it becomes clear what the size of 1 carat in full size according to the table of carateness is 6.4 mm. 

    That is, if you have measured the diameter of the stone, then it is not difficult to determine how many carats it contains. But these indicators are also indicative.  

    For diamonds of various shapes, there is a custom table: Marquis shape pear heart emerald oval Size (mm) 9,8*5,6 8,6*5,8 6,7*6,5 6,4*4,9 7,7*5,9  

    When the weight changes, the value of the stone changes exponentially. A diamond weighing 2 carats costs 4 times as much as a single-carat stone of exactly the same quality. Big diamonds don't have a constant price on the market at all.
