The Gemological Institute of America, called the GIA for short, is probably the most commonly used program for evaluating diamond coloring. They've produced some thing called the “GIA Colour Grade Scale”, and it has placed a grading system about the many various colors and shades of diamonds, classifying into 22 letter grades.
How Diamonds are Graded
The Gemological Institute of America has certified diamond color grades as “master colour comparison” diamonds. When a diamond is getting graded, it is compared against these master colour comparison grades, to locate the shades that match it most closely. The diamond that is being graded ought to be thoroughly cleaned and all oil ought to be removed from the surface just before becoming examined, since even small amounts of dirt or oils on the surface from the diamond can alter the colour.
A line of master coloring comparison diamonds or shade chart is set up, with every grade placed about one inch apart, ranging in the lightest and highest graded D shade, towards the darkest, graded Z diamonds. The diamond colour which is becoming graded is moved from the left side from the comparison units to the proper, until it matches a single of the shades.
Diamond grading should take place in a colorless environment, making use of a balanced fluorescent light source that has a filtered, cool white sun like ray. The room where the grading takes location is dark, all except for the specific grading light, in order to obtain probably the most accurate grading with the diamond colour.

Fluorescence of Diamonds
Yet another consideration when considering the diamond color is diamond fluorescence, and how it will effect the actual appearance within the diamond color. Fluorescence causes some diamonds to transform colour when viewed in our everyday, ultraviolet lighting, too as under fluorescent light bulbs.
When a diamond color is graded, the strength from the fluorescence of that diamond must also be indicated. It might be considered being strong, moderate, or weak fluorescence, and the reports ought to also indicate what colour the diamond will change to due for the fluorescence. The reason for this is when people are within the jewelry shop, looking at diamonds in the unique lighting from the shop, they might all appear to become the colorless, transparent diamonds. When you purchase a diamond and get it house below normal lighting, you could discover your diamond is yellowish in colour!
You are able to ask your jeweler to provide grading documentation and details about the fluorescent value of a particular diamond just before purchasing, to ensure that you will be happy with the diamond you acquire. Many jewelers also can show you the diamond below diverse lighting conditions, which will enable you to fully appreciate the beauty from the diamond before you acquire it. Some individuals like a diamond colour with a darker shade, while others are insistent on the transparent diamond colour. The diamond color is 1 of personal preference, so be certain to do a little research prior to making your final selection.
