Talking about gemstones, colors play a crucial role, not only in determining their beauty but in evaluating their prices as well. You may wonder, how gemstone colors help in deciding the value, the whole procedure is defined below.

Since the beginning of capitalism, there have been a number of methodologies to define the value of gemstones. This means that evaluation of the gemstone prices has been an evolving process. The color is one of the major 3 factors responsible for determining the value, in addition to carat and cut. The importance and extent of this factor can be estimated by the fact that color alone may account up to 50-70% of the value of a gemstone.

'Color' in a gemstone is a combination of 3 factors, hue, tone, and saturation. All of these 3 together create what we see as the color of the gemstone. Well, being the most advanced creation of God, our eyes can see up to 10 million different colors. The first thing to understand is the hue. 'Hue' means the base color of the gemstone as blue, green, yellow, red, brown and so on. These hues combine together to form additional hues as well. The Geological Institute of America (GIA) has identified 31 base hues, including 7 original and 24 combination hues.

The second component of the color is its tone, which describes the darkness or lightness of a color. This means that a blue gemstone can be light blue, dark blue or even medium blue. The GIA has identified 11 tones ranging from colorless to complete black tones.

Third and the last component of gemstone color is the saturation. This component defines the degree of intensity of the color of the gemstone. As per the GIA guidelines, the saturation groups hues in 2 categories, cool and warm hues. The cool hues include blue and violet, and the warm hue includes orange and red hues. On the decrease in the colors of cool hue, they tend to turn greyish, whereas, the colors of warm hue turn brownish.

For the evaluation of the value of a gemstone, the relationship between hue, tone and saturation are very important. With the enhancement in saturation, the color of gem turns darker. As per the GIA, the most valuable gemstones have a 6-vivid on the scale of saturation. The highest tone value of a valuable gemstone is 8. As the gemstones are the product of nature, they tend to have a different level of tones, with the most common varying between 5 to 6 on the saturation scale.

The gemstones astrology and gemstone benefits also add up to the value of stones, in addition to the 3 C's. All these together mark the value and price of the gems.
