Diamond Colour – Evaluating Diamond Colour
What precisely is diamond coloring? Although most people think with the classic, transparent diamond, which happens being one of the most rare and valuable, the colors of diamonds in fact range from transparent all the way to a brownish color. You will find diverse saturations of diamond coloring, and tones.

The Gemological Institute of America, called the GIA for short, is one of the most commonly employed system for evaluating diamond colour. They’ve created some thing known as the “GIA Coloring Grade Scale”, and it has placed a grading system around the several various colors and shades of diamonds, classifying into 22 letter grades.
How Diamonds are Graded
The Gemological Institute of America has certified diamond coloring grades as “master color comparison” diamonds. When a diamond is becoming graded, it is compared against these master color comparison grades, to find the shades that match it most closely. The diamond that is becoming graded should be thoroughly cleaned and all oil must be removed in the surface before being examined, since even small amounts of dirt or oils around the surface of the diamond can alter the colour.
A line of master coloring comparison diamonds or shade chart is set up, with each grade placed about a single inch apart, ranging from your lightest and highest graded D shade, to the darkest, graded Z diamonds. The diamond colour that is becoming graded is moved in the left side with the comparison units to the correct, until it matches 1 with the shades.
Diamond grading ought to take place 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 place is dark, all except for the special grading light, so that you can obtain probably the most accurate grading with the diamond colour.

Fluorescence of Diamonds
Yet another consideration when considering the diamond coloring is diamond fluorescence, and how it will effect the actual appearance in the diamond color. Fluorescence causes some diamonds to change coloring when viewed in our everyday, ultraviolet lighting, as well as under fluorescent light bulbs.
When a diamond coloring is graded, the strength from the fluorescence of that diamond should also be indicated. It may be considered to become strong, moderate, or weak fluorescence, and also the reports ought to also indicate what coloring the diamond will change to due towards the fluorescence. The reason for this is when people are inside the jewelry store, looking at diamonds in the special lighting from the shop, they might all appear being the colorless, transparent diamonds. When you purchase a diamond and get it house beneath normal lighting, you could locate your diamond is yellowish in color!
You can ask your jeweler to provide grading documentation and details about the fluorescent value of a specific diamond just before purchasing, to make certain that you’ll be happy with the diamond you purchase. Several jewelers also can show you the diamond below various lighting conditions, which will enable you to fully appreciate the beauty with the diamond just before you buy it. Some individuals like a diamond color with a darker shade, while others are insistent around the transparent diamond color. The diamond colour is a single of individual preference, so be certain to do a little research just before making your final selection.
