Imperfect Inclusions, I1 - I2 - I3
Diamonds graded in this category have inclusions that visible with an unaided eye, when viewing the diamond from the top about 6 - 8 inches away from the eye. The size, location, and number of inclusions affect the grade. An I1 graded diamond has only one eye visible inclusion located toward the edge of the diamond with several smaller non-visible inclusions. I2 has several eye visible inclusion on the edge or just one located in the center of the stone. I3 rated diamonds have eye visible inclusions scattered around the diamond.

For a very good reason, many people are not confident to determine the clarity grade of a diamond. People can very easily misread a diamond’s clarity without the proper education and instruments. But, you can identify a diamond’s clarity rating by following the steps shown below: 1) look only at loose (unmounted) diamonds. It is very difficult to view the inclusions when the diamond is mounted in a setting. 2) Always use a microscope. A loupe is only used by experienced jewelers to grade diamonds. It takes several months of experience for using a loupe to accurately identify a diamond’s clarity. Therefore , A lighted 10X power microscope is recommended, regardless of your clarity grading skills. You are able to see every inclusion in a diamond by using a microscope.
The most popular method of grading a diamond is developed by the Gemological Institute of America, GIA. The GIA independent diamond grading report is the most accurate and trusted report in the diamond trade.
D) Diamond Color
The diamond colors are the actual body color of a diamond, and it has range from colorless to light yellow. The more yellow is the diamond, the lower is its quality. Do not confuse color with brilliance which is a function of the diamond cut. The diamond should be viewed with table facing down, so the diamond’s brilliance does not interfere with the view of diamond color. It is very difficult to judge the color of a diamond when its mounted on a set.

GIA Color Grading System
Diamonds graded D, E, or F are considered to be called fine “white diamond” or more precisely colorless diamond. A proper diamond cut is still the most important factor, but a combination of an excellent cut and a colorless diamond is very appealing. Diamonds graded G, H I, or J are in the near colorless range. It has a slight yellow body color noticeable when compared to a higher rated color stone and viewed with table side down, on a white surface next to each other. An ideal cut diamond mounted in a ring with a color of I is very hard to separate from a matching ring with a diamond graded E. The intense brilliance of an ideal or premium cut diamond mask the sight difference in body color. Diamonds graded K, L, or M have a noticeable yellow color body when viewed from the top of the stone and clearly visible when viewed with table faced down. Diamonds in this color range have an obvious yellow body color even when mounted in a ring. Diamonds graded in the range of N - Z are very obvious yellow when viewed from top or bottom of the stone.

Color grading is done by comparing a diamond of one color to that of another. This is done by placing two or more diamonds next to each other with table down on a white surface and viewing them through the their pavilions or bottoms. Usually, a diamond trader will have a Master Grading Set of diamonds which is a small group of diamonds in each of various color grades that have been graded by an independent Gem Lab. As a beginner, one can not expect to differentiate between an “F” and a “G” colored diamond. The color difference is so slight that only an expert can tell the difference, and because of subjective nature of diamond grading, even two experts do not always agree.
Unlike diamond Clarity, where one can lower the grade without affecting the appearance, diamond Color becomes eye visible after letter “J”. One should try to select a diamond within the range of “E” to “J” color. From color “J” and above, the stones progressively appear more yellow.
