What does "color range" refer to in gemology?

In gemology, "color range" specifically refers to the selection of colors in which a gemstone can occur. This term encompasses the various hues and shades that a particular type of gemstone can exhibit, reflecting the natural variations in color due to factors like chemical composition, crystal structure, and environmental conditions during formation. Understanding the color range is crucial for gemologists as it helps in identifying gemstones and assessing their uniqueness and potential value based on their colors. Some gemstones, like sapphires, can be found in a wide range of colors, while others may be predominantly one color. This concept is essential when evaluating gemstones in terms of beauty, rarity, and market demand.
