Grade color Diamond
What is a diamond of color? Although most people think of the classic, transparent diamond, which was the scarcest and valuable, the colors of diamonds actually range from transparent all the way to a brownish color. There are different color saturation diamond, and ring tones.
Gemological Institute of America, known as GIA for short, is the most commonly used system for evaluating Diamond color. They created something known as “GIA color grade scale”, and she put a grading system in many different colors and shades of diamonds, classifying into 22 classes of letter.
How Diamonds are Graded
Gemological Institute of America has certified Estimates Diamond color as “Master of the color comparison” diamonds. When diamonds are being graded, it is compared with these Master Classes comparing colors to find the shades that match it most. Diamond, which is being graded, must be thoroughly cleaned and all oil must be removed from the surface to be considered, since even a small amount of dirt or oil on the surface of diamond can change the color.
Line master color comparison diamonds or color chart is created, with each grade placed about one inch from each other, starting with the easiest and senior-ranking shadows D, in the darkest, graded Z diamonds. Diamond color that is being graded is moved from the left side of the comparison units to the right until it coincides with one of the shades.
Brilliant must occur in a colorless environment, using a balanced fluorescent light source that is filtered, cool white sun like ray. The room where the sorting is dark, all except the special light of classification, in order to obtain the most accurate classification of diamonds color.
Fluorescence diamonds
Another consideration when considering Diamond color fluorescence, and how it will affect the actual appearance of diamond color. Fluorescence causes some diamonds to change color when you look in our everyday, ultraviolet lighting, as well as under fluorescent lights.
When graded Diamond color, the strength of the fluorescence that diamond must also be specified. This can be seen as strong, moderate, or weak fluorescence, and the reports should also indicate what color Diamond will change due to fluorescence. The reason for this is when people are in a jewelry store, looking for diamonds in a special lighting store, they can all seem a colorless, transparent diamond. When buying a diamond and get it home under normal lighting, you can find yellow diamonds!
You can ask your jeweler to provide the classification of documents and information about the fluorescent value of a particular diamond before purchasing to make sure that you’ll be happy with the diamond you are buying. Many jewelers also can show you the diamond under different lighting conditions that will allow you to fully appreciate the beauty of a diamond before you buy it. Some people, like a diamond color with dark shadows, while others insist on transparent color diamond. Diamond color is one of personal preference, so do not forget to do some research before your final choice.
