Judging the purity of ruby


The degree of describes to which the hue is masked by brown or gray. Intensity, strength, and saturation are words for color purity. The evaluating of ruby color, even though it’s debatable as to what are the most valuable ruby hues and tones, gem dealers agree that pure, vivid colors are far more desirable than dull, muddy, brownish colors. To learn to judge color purity, look at the red objects around you and yourself which reds look the brightest and which look the most drab. Also go to a jewelry store and look at some rubies and red garnets side by side and try to determine which ones have the least amount of brown. Just being aware of color purity will increase your sensitivity to it. This in turn will help you choose a more desirable ruby.
Judging the lightness or darkness of faceted gemstones is difficult because they don’t display a single, uniform tone. They have light and dark areas which become more apparent as you rock the stones in your hand. To judge the tone of a faceted ruby, answer the following questions:
-    What is your first overall impression of the toe? Use one of the above lightness/darkness terms to describe the stone. If it is light or very light, the stone is either a pink sapphire or a lower-quality ruby, depending on the country where it’s sold. For rubies, medium to dark tones are preferred by the trade.
-    Do you see nearly colorless, washed-out areas in the ruby? This is an indication of poor color, poor cutting, or both.
-    What percentage of the ruby looks black? If more than 90% of it is blackish, gem dealers would classify it as undesirable. The purpose of owning colored stones is to see color, not black.

Judging the hue of a ruby is just as hard as judging the tone. The different tones and possible brownish tints are distracting. Moreover, rubies are a blend of two colors-purplish red and orangey red. When you look at the rubies from different directions while moving them, you can see these two colors. This is due to certain properties of corundum and cannot be removed.
That is a right attitude to learn more experience from more experts before you make a decision to buy ruby. Ask for any query from most of the online jewelry wholesale stores and they suppose will provide detail information. Or walk around fine jewelry stores and you’ll find out the jewelers experts are willing to tell you more.
