This is the intensity or how strong the color of the gemstone is shown to the eye. If the colors are even and strong with good brightness then the stone may have a good saturation. Often good saturated stones will have the color originating from the bottom of the gemstone and reflected throughout the stone.


This refers to how light or dark the color of the gemstone may be visible to your eyes. Colors of gemstones may vary to numerous tones, it is up to our eyes and mind to determine which color is optimal not too light or dark when choosing gemstones.

However tastes of people in different countries vary some people prefer the lighter tones and some prefer the darker or brighter colors. There are many gemstone hues that range the entire color spectrum from red to violet. The most valuable colored gemstones will have vivid color saturation and fall in the middle of the hue and tone grading scales. There are specific vivid hues considered highly desirable in different gemstones. Some of the color descriptions you will see include “cornflower blue” when describing blue sapphires, “pigeon’s blood red” when describing rubies. These color descriptions are meant to communicate the most valuable hues in precious gemstones.


Gemstones that originate as crystals go through a process of gem cutting in a lapidary to take the form of a gemstone. The cut refers to the specific design used to cut gemstones, there are various shapes that gemstones can be cut based on the material and color of the gemstones. Sometimes the shape of the gemstone would demand a higher price for examoke a round shape and cushion shapes may demand a higher market price. Each shape of gemstones will go through suitable cuts eg: Brilliant cut, princess cut, radiant cut ect.


Clarity refers to the internal characteristics of a gemstone or the surface of gemstones. Crystal may have natural inclusions that are naturally evident in gemstones and are part of the formation or beauty of gemstones. Inclusions in gemstones may take a variety of forms that are a complete different area of study itself. A high clarity gemstone may be classified as one where the color and beauty of the gemstones may be realized without any interference from inclusions. You may find certain stones demand a higher price with good clarity such as sapphires, and others like Emeralds even with low clarity may be priced higher. Certain gemstones may be valued higher only because of any interesting inclusions that the gemstone processes making the gemological value higher and rare.

This refers to the unit of measurement of the gemstone, 1 carat is equal to 0.2 grams. Gemstones that are rare such as good color natural untreated sapphires may be rare in large sizes. The size of the gemstone increasing means the price will be higher larger gemstones will demand a higher price. Different gemstones may have different densities, it will be interesting to see gemstones of the same carat weight have different sizes.
