The Gemological Institute of America, generally known as the GIA for short, is probably the most commonly used system for evaluating diamond color. They’ve produced something known as the “GIA Color Grade Scale”, and it has placed a grading system about the numerous diverse 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 color comparison” diamonds. When a diamond is being graded, it is compared against these master coloring comparison grades, to locate the shades that match it most closely. The diamond that’s getting graded must be thoroughly cleaned and all oil should be removed from your surface before becoming examined, since even small amounts of dirt or oils on the surface from the diamond can alter the color.

A line of master color comparison diamonds or shade chart is set up, with each grade placed about a single inch apart, ranging in the lightest and highest graded D shade, to the darkest, graded Z diamonds. The diamond color that is being graded is moved from your left side with the comparison units for the right, until it matches one with the shades.

Diamond grading should take location in a colorless environment, using 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 special grading light, to be able to obtain probably the most accurate grading of the diamond coloring.

Fluorescence of Diamonds

Yet another consideration when considering the diamond coloring is diamond fluorescence, and how it will effect the actual appearance within the diamond color. Fluorescence causes some diamonds to alter color when viewed in our everyday, ultraviolet lighting, as well as below fluorescent light bulbs.

When a diamond color is graded, the strength with the fluorescence of that diamond should also be indicated. It might be considered to become strong, moderate, or weak fluorescence, and also the reports should also indicate what coloring the diamond will change to due for the fluorescence. The reason for this is when folks are within the jewelry shop, looking at diamonds in the unique lighting from the store, they might all appear to be the colorless, transparent diamonds. Whenever you purchase a diamond and get it house beneath normal lighting, you could discover your diamond is yellowish in colour!

It is possible to ask your jeweler to offer grading documentation and information about the fluorescent value of a particular diamond prior to purchasing, to ensure that you will be happy with the diamond you purchase. Numerous jewelers also can show you the diamond beneath different lighting conditions, which will enable you to fully appreciate the beauty with the diamond prior to you purchase it. Some individuals like a diamond colour with a darker shade, although others are insistent around the transparent diamond color. The diamond coloring is one of personal preference, so be certain to do a little investigation prior to making your final selection.
