Evaluating Diamond Color
What exactly is diamond color? While most people think of the classic, transparent diamond, which happens to be the rare and valuable, the colors of diamonds actually range from transparent all the way to a brownish color. There are different saturations of diamond color, and tones.
The GIA is the most commonly used system for evaluating diamond 4cs, and this type of diamonds called GIA certified diamonds. They've created something known as the “GIA Color Grade Scale”, and it has placed a grading system on the many different colors and shades of diamonds, classifying into 22 letter grades.
How Diamonds are graded
Gemological Institute of America has been certified diamonds color grades of "master color comparison" diamonds. When a diamond is graded, it is compared to these masters of color degrees of comparison, looking for nuances that best matches. Diamond, which has been criticized, is clean and all the oil is removed from the surface before being examined, since even small amounts of dirt or oil on the surface of diamond can change the color.
A line of master comparison diamonds or color sample set, with each grade placed about one inch apart, ranging from the lightest shade and D the highest rank in the darkest, sorted diamonds Z. The color of the diamond is classified moves from the left side of the unit compared to the right until it matches one of the nuances.
GIA Diamond Grading should be done clearly, using a balanced source of fluorescent light that has filtered sun, cool white, like lightning. The room where the classification takes place is dark, all except for the special light of the notation, to obtain more accurate color grading diamonds.
Fluorescence of Diamonds
Another consideration when considering the color of the diamond is diamond fluorescence, and how they affect the actual appearance of the color of the diamond. Fluorescence makes some diamonds to change color when viewed in our daily lives, ultraviolet light and under fluorescent lights.
When a GIA certified diamonds rated, the strength of the fluorescence of a diamond is also mentioned. Can be considered strong, moderate or weak fluorescence, and the reports must also indicate what changes the color of a diamond because of fluorescence. The reason for this is when people trade in gold, diamonds, looking at shop, special lighting, all seem to be a colorless, transparent box. When you buy a diamond and make it home under normal lighting conditions, you can find the diamond is yellow!
You can ask the jeweler to provide grading documentation and information value of the fluorescent light, in particular diamond before you buy, make sure you're happy with the diamond buying. Many jewelers also can show you the diamond in different lighting conditions, allowing you to fully understand the beauty of a diamond before you buy. Some individuals like a diamond color of a darker shade, while others are firmly attached to a transparent diamond color. Diamond color is one of personal preference, so be sure to do a little research before making your final choice.
