In the context of colored gemstones, saturation refers to what?

Saturation in the context of colored gemstones specifically refers to the intensity of the color. A gemstone with high saturation will exhibit a vivid and strong color, while a gem with low saturation may appear dull or washed out. This characteristic is crucial for determining the overall quality and value of a colored gemstone, as vibrant, highly saturated colors are typically more desirable.

Understanding saturation allows gemologists and consumers alike to assess and compare the visual appeal of various gemstones more effectively. The intensity of the color is a key factor in grading, as it can significantly influence a gemstone's marketability and aesthetic qualities.
