There are several kinds of diamond certifications available in the world. They are issued by different institutions and each of them has its own special features. You may hear of GIA and IGI. Then how about AGS? Do you know anything about it? bbcblogging

AGS is the abbreviation for American Gem Society. It was found by Robert M. Shipley in 1934. At the beginning of 1990, AGS was dedicated to develop the grading system of the diamond. After the system is developed, it is found that it is different from other types of certification systems greatly. Besides the weight, it divides the color, clarity and cut of the diamond into 11 levels from 10, which is the worst level, to 0, which is the best level. Other than that, the AGS prides itself on being the original lab to provide diamond cut grades. The cut of a diamond is considered as the most important factor among the 4 C’s of diamonds because it determines how well the diamond reflects light. bbcgloble

From 1996, AGS certification has become the cutting criterion in the international diamond field. If the cutting level is 0, it means the diamond cutting is perfect. If you see three 0’s, it means the polish, proportions and the symmetry of the diamond is perfect. It has the best light performance. dimondtime

Now you know what the AGS Certification is. If an AGS Certification is presented before you, do you know how to read it? The following is the information recorded on it:

1 Laboratory Report

It means the number of the verification certificate.

2 Date

It means the date when the diamond is identified.

3 Weight

It describes the weight of the diamond with the unit Carat.

4 Shape and Style

It describes the shape and the style of the diamond.

5 Measurements

It describes the size of the diamond with the unit millimeter.

6 Total depth percentage

It is the ratio of the total depth of the diamond (from table to culet) as compared to the total diameter.

7 Table percentage Bravoblogging

It is the ratio of the table width as compared to the total width of the diamond.

8 Girdle

It describes how thick the girdle is.

9 Culet

It describes the appearance of the culet.

10 Polish

It describes the level of polishing.

11 Symmetry

It describes the level of symmetry.

12 Clarity grading

It describes the diamond’s clarity level under a 10 times magnifying glass.

13 Color grading universalblogs

It describes the grading of the diamond color.

Finally, there is one thing I want to tell you. If the diamond is of high quality, it must be very valuable. It must have good reflective ability and good symmetry, but its cutting won’t be so perfect.
