Do You Know Anything About the AGS Diamond Certification?

There are diverse kinds of diamond certifications available in the earth. They are issued by different institutions and harvested land of them has its own particular features. You may hear of GIA and IGI. Then to what extent about AGS? Do you know anything about it?

AGS is the abbreviation despite American Gem Society. It was set up by Robert M. Shipley in 1934. At the rise of 1990, AGS was dedicated to unravel the grading system of the carbon crystal. After the system is developed, it is set up that it is different from other types of certification systems greatly. Besides the mode of estimating, it divides the color, clarity and divide of the diamond into 11 levels from 10, which is the worst level, to 0, what one is the best level. Other than that, the AGS prides itself up the body being the original lab to arrange diamond cut grades. The cut of a lozenge is considered as the most significant factor among the 4 C's of diamonds for the cause that it determines how well the diamond reflects light.

From 1996, AGS certification has grow the cutting criterion in the international diamond field. If the cutting proportion is 0, it means the diamond cutting is perfect. If you suffer three 0's, it means the brilliance, proportions and the symmetry of the crystallized carbon is perfect. It has the most good light performance.

Now you know which the AGS Certification is. If one AGS Certification is presented before you, translate you know how to read it? The following is the accusation recorded on it:

1 Laboratory Report

It ways and the number of the verification credential.

2 Date

It means the era when the diamond is identified.

3 Weight

It describes the pressure of the diamond with the one Carat.

4 Shape and Style

It describes the produce and the style of the brilliant.

5 Measurements

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

6 Total depth percentage

It is the proportion of the total depth of the lozenge (from table to culet) as compared to the whole diameter.

7 Table percentage

It is the rate of the table width as compared to the lump width of the diamond.

8 Girdle

It describes how thick the girdle is.

9 Culet

It describes the show of the culet.

10 Polish

It describes the level of polishing.

11 Symmetry

It describes the of the same rank of symmetry.

12 Clarity grading

It describes the diamond's clarity level under a 10 spells magnifying glass.

13 Color grading

It describes the grading of the crystallized carbon color.

Finally, there is one deed I want to tell you. If the crystallized carbon is of high quality, it be under the necessity of be very valuable. It must obtain good reflective ability and good shapeliness, but its cutting won't be so perfect.
