The hue of a gemstone refers to the specific shade of the gemstone. Common gemstone colors can include many different combinations and variants of the six basic hues: red, orange, yellow, green, blue, and purple. Each type of gemstone tends to have a common or preferable hue, but the same type of gemstone can actually be a variety of colors. For example, most people think of diamonds as being clear, but there are about 300 different hues of diamonds that naturally occur. Some gemstones, such as a ruby and an emerald, can actually have the same hue, even though their mineral compositions are entirely different.
Saturation is the level of purity of a hue within a gemstone. High saturation makes a gemstone’s color more pronounced. A pure color does not have any brown, black, or greyish tints that make the gemstone color appear muted or dull. A highly saturated jewel will have a bright and vibrant color, and a gemstone with a high saturation level will most likely be quite valuable.
When people speak of a gemstone’s tone, they are referring to the lightness of a gemstone. Technically, the tone is determined by how much light the gemstone absorbs. Tone is divided into five gradients: dark, medium-dark, medium, medium-light, and light. In general, most people prefer gemstones that have a medium tone, so those are more expensive. Saturation and tone are somewhat interconnected, since gemstones with a dark tone are usually less saturated.
