Carats of diamonds

Carats of diamonds

    As is known, the weight of a diamond is measured in carats. This jewelry value on everyone's lips, it is measured by value, size, in general - the more carats, the luxurious stone. This is a common statement. However, remember that 1 carat pure stone and diamond of the same size with the marriage or outside the natural inclusions - they are very different and significant differences in price. Carat diamond - this is important, because the size of the gem - perhaps the main characteristic of the external decoration. In this article we look at what is 1 carat, which stone to choose, how to assess their own decoration. Let us begin with the history of the emergence of weight and some features of the notation. 

Large selection of diamonds and luxury jewelry.

   1 Carat is 200 milligrams, and uses this value to 1913, when most of the world has passed to such a system. Abbreviated 1 Carat will be written as 1 ct. many confuse this reduction with kt. This is wrong, because most are in the United States reduced the purity of gold.

     Carats diamonds differ quite strongly, if it is a stone that was purchased prior to 1913. Then there was the official overall system, so the carats of diamonds differed significantly from not only the 'modern', but also by countries. For example, the 1910 diamond, weighing 1 carat, purchased in England, will differ from similar French products. As a rule, carats of diamonds then were much larger than today. Then there is the old stone 1 Carat will weigh more similar weight.

     1 Carat is called modern metric carats and is one fifth of a gram, as already mentioned.

 Carats of diamonds is not the only measure of weight 1. Karat contains 100 so-called 'points.' It 'points' is often used to refer to the weight of small and medium-sized gems.

It is important to remember that the carats of diamonds is not their size. 1 Carat Diamond will differ from another gem of a similar weight. In this case, the role played by the density and the presence of inclusions within the gem. For example, Ruby diamond jewelry is heavier, so it will be visually less than brilliant. 

      When we are talking only about diamonds, you can safely say that diamond carats almost always can say a lot about the size of the gem. For example, a small table, matching diamond weight:

Weight           Girdle diameter               Weight               Girdle diameter

0,5 carat            5,1 мм                       4 carat                    10 мм

1    carat            6,4 мм                       5 carat                    11 мм

1,5 carat            7,3 мм                       6 carat                  11,7 мм

2    carat            8,1 мм                       7 carat                  12.4 мм

2,5 carat            9,1 мм                      10 carat                   14 мм

3    carat            9,4 мм

In this case the carats of diamonds correspond to the size of a round cut with 57 facets.

 If the stone weighs less than 0.01 carats, it's considered diamond grit, which is also used in the jewelry business.

How to calculate the exact weight of the diamond and its value?

 Is 1 carat, grams, divided 5. Gem diamonds is a rather complex figure, but almost always after the purchase to make sure the right data is indicated on the label. Make it easy enough even when stone is rim. To calculate one karat jewelry weighs gem or more, you can use the formula:

Mass = (diam.*2) * height * 0.0061

For lack of jewelry scales, carat diamond fairly accurately determined by a formula. However, remember that the jewelry carat - the sensitivity. Marriage slightest cut, not even noticeable eye, will cause that Carat will be calculated incorrectly.

How to determine the value of the diamond using the gem?

 Gem diamonds very strongly influences the cost of these gems ... in this case, there is a clear relationship, all other things being equal,. i.e. jewelry Carat — there's more you need to take into consideration the purity of diamond, color, as well as the quality of the cut. Generally speaking, every next jewelry Carat will cost much more expensive. Dependency here which. Gem diamonds, erected in the square, and will thereby increase the odds of. i.e. two-Carat Diamond will cost three times more 1 karat, 4 Carat will have 15 times more expensive. One karat jewelry is usually measured by global standards.

Large gems do not obey this rule. Jewelry Carat in this case does not play a role, because such large stones is collectible, luxury items. Here it's not so much about gem diamonds, how about the purity, tint, defects, cut, shape, and, of course, history.

Alas, accurately assess stone alone will not succeed, because very often the cut is far from perfect. The assessment can affect the availability of any chip or invisible scratches, and the formula to see or quantify. 

Categories of diamonds 

 Gem diamonds is one of the species classification of rare gems. Stones come small, medium and large. To small are gems, which weigh between 0.01 up to 0.29 carats, average is 0.3 -0.99 carats and larger are those whose weight is 1 Carat jewelry and more ...

Gem small diamonds allows you to evaluate them only by weight, with the cost framework remain fairly stable. The situation with medium-sized stones. This group of diamonds is almost always the same, subject to world average rates. As a rule, for the formation of value are used generally accepted evaluation table.

    Those diamonds over one carat jewelry evaluated quite differently. In this case, necessarily takes into account the colour and purity of tone. A colorless diamond is always more expensive than the one that contains the 'impurity' of other colors. Next, always strictly assessed clean stone, the presence or absence of impurities in it. In addition, gem diamonds this group implies a complete lack of marriage, cracks, chips and scratches.        These diamonds are a staple of auctions and are often found in private collections. This group includes historic diamonds, which have a long history and 'untwisted' name. When evaluating large samples is taken into account not only the obligatory gem diamonds, but the origin of the stone deposit and how to cut.
