The rules for choosing jewelry: how to determine if there is much in ordinary diamond carat? 1 carat - is how many grams?

Like fashion for clothes or shoes, in preferencescertain jewelry also has its own tendencies. Only the eternal classics does not change: exquisite rings, bracelets, pendants and diamond earrings still fascinate with their beauty. Every beauty dreams of becoming an owner of stones at least a few carats. One diamond can reach a weight of several dozen carats, and in order to understand whether it is a lot or a little, several factors need to be taken into account.

What are diamonds

By themselves, diamond stones are formed in specialnatural conditions, where there is everything necessary for the formation of a crystal. And basically, their birth is more likely in highlands. Large-sized diamonds are a rarity, and there are much more small stones among them. Therefore, even a copy weighing several carats is very expensive.

A diamond cut diamond is calleda diamond. Since when grinding each stone becomes unique, but loses several carats in weight, the same diamond before and after processing varies in cost hundreds of times.

How are stones evaluated?

Large and small diamonds are estimated at differentcriteria. In the first case, color and clarity matter, in the second - weight, but not the individual characteristics of the stone. The unit of weight of these gems is considered to be a carat - 1 millet grain.

This is only an approximate measure, and, on itschange is influenced by the most unusual factors. The same weighing, carried out at different levels of humidity, gave discrepancies of up to 0.13 grams. With the expansion of the geography of the jewelry trade, it became necessary to give this unit of measurement an exact meaning.

Systematization of measurements

In 1877, French traders offeredestablish the official figure: 1 carat should be 0.205. The proposal was not supported, but after a quarter of a century, in 1907, at a conference in Paris, the issue of systematization of uniform measures and weights was raised again. Even later, in 1930, the final international weight measure was approved, which allows to determine exactly what 1 carat is. “How many grams does this stone weigh?” Buyers often ask managers of jewelry salons. Today, its measure is 0.2 grams (i.e., 1/5 part) or 200 mg.

In addition, there is another possibility to determine how much a carat weighs. 1 diamond of this mass is considered to be equal to 3.086 troyan gran, used for weighing large precious stones.

In the professional environment, jewelers decided to determine the mass of stones differently. We can say that a carat is 1 hundred points (a unit often used as an indicator of the weight of small and medium stones).

Features of weighing different stones

Is it a lot: 1 carat?How many grams does a standard diamond weigh? Usually its weight is measured with the highest accuracy to hundredths, and the weight is established using sensitive carat weights. It can be approximately determined by the diameter of the stone. Very large diamonds weighing over 6 carats are sold only at auctions, they denote melange.

Small stones, weighing no more than 0.25 carats, -publicly available, and they are called melee. If their weight does not exceed 0.01 carats, then this is diamond grit, which is also important in jewelry. Abbreviated 1 carat is indicated as 1 ct, such an abbreviation should not be confused with the abbreviation kt used to denote the purity of gold in America.

What does a 1 carat stone look like?A diamond can have a diameter of up to 6 mm and a height of up to 4 mm: it does not look too impressive. It all depends on the density and inclusions in its composition. When it comes to diamonds, carats can tell a lot about their size. For example, a diamond's carats correspond to its size if they have a round faceting with 57 facets.

How to choose the right diamonds

Jewelers recommend applying the rule of four"Si" (English - C): carat - carat; clarity - purity; color - color and cut - cut. The main indicator - weight, the more it is, the higher the cost. A high-quality diamond should not have a color; with its ideal color, it becomes imperceptible in water. It is from here that the expression "pure diamond" appeared.

By color, diamonds are divided into classes.The first class is also among the Russian stones, although more often they belong to the second or third. If they have no internal defects, it means that they are “clean”. A similar classification allows to distinguish among them diamonds that do not have cracks visible to the naked eye or under the enlarger. The cut is already an element of decor. In general, round stones are offered for sale, although, if desired, another form can be ordered.

Distinguish a real diamond from a fake forIt is difficult for an ordinary buyer, but you should always pay attention to the mark with the number of faces. Price depends on it. For example, the marking on the label 1Kr 57–0.25 1 / 5A means that it is a round stone, one with 57 facets, which weighs 0.25 carats, with a color of 1 class and a purity of 5A. A ring with such a stone will cost about 25,000 rubles. Products with diamonds up to 0.1 carats do not exceed 7,500 rubles at a cost. A half-carat stone will cost 150,000 rubles, but this is not a very expensive diamond. 1 carat price can exceed half a million rubles.
