Usually on the tag jewelry with diamonds you can find the information of this type: 1 Br Cu-57 0,08 2/3A. This means that the decoration contains 1 diamond round shape with 57 facets. Gemstone weight of 0.08 carats. Figure 2 indicates the characteristics of color, and 3 purity. Letter A refers to quality of cut.
So, to begin to learn the characteristics of the diamond, first and foremost, pay attention to its weight in carats. 1 carat (ct) equals 200 milligrams, or 0.2 g. All diamonds are divided into small (up to 0.29 ct), medium (0,30 – 0,99 ct), large (over 1 ct). There is a relationship between the weight of a diamond and its diameter. For example, stone weight is 0.50 ct with perfect adherence to the technical specifications for polished diamonds will have a diameter of 5.2 mm. Respectively, the greater the weight of the diamond, the greater its diameter, as well as the cost.

In the domestic classification of diamond clarity is indicated by the numbers 1 to 12. And 1 – net under a magnifying glass the diamond; 9-12 – diamondswith inclusions visible to the naked eye. For diamonds up to 0.29 ct of a similar scale has a range from 1 to 9. The system of GIA diamonds with the highest purity group denoted by the letters IF, then there is a gradation of species VVS1, VVS2, VS1, VS2, SI1-SI3, I1-I3. Group purity I3 corresponds to the 11-12 group in the Russian classification.
Finally, review the information on the form and quality of cut. The most popular and expensive is the round cut diamond Kr-57. There are also many fancy shapes: pear (G-56), Marquis (M-55) oval (S-57), Princess (P-65), baguette (B-33), trilliant (T-55) and other fancy shapes are stylish and impressive look in jewelry.
The cut grade in Russian classification is denoted by the letters A, B, C, d where A is best quality, D – unsatisfactory. Under the cut grade refers to the ratio of the linear dimensions and angles, Polish and symmetry. From all these parameters depends on the luster and play of light in the stone. In the GIA system best quality of a diamond is denoted by the word excellent, followed by such gradations as very good, good, worst is denoted as poor.
In the price lists for diamonds, there are many transition groups which differ significantly in price. For example, the difference in cost cut diamonds with a weight of 0.49 ct and a weight of 0.50 ct can be 200-300 dollars, while outside the transition groups in each of 0.01 ct, the price increases only by 20-30 dollars. The same applies to the diamond weight is 0.29 ct and 0,30 ct; 0,69 ct and 0.70 ct; 0,99 ct and 1.00 ct. But visually between such stones almost imperceptible differences.
