Gemstone Color

The color of a gemstone is its most defining characteristic. When deciding upon gemstone color, examine the hue, tone, and saturation.

The most valuable gemstones are those that exhibit a pure color and only “slight” hues of other colors in addition to their primary color. The tone represents the depth of color, ranging from colorless to black. Gemstone tone is described as “light,” “medium-light,” “medium,” “medium-dark,” and “dark.” The saturation, or color purity, refers to the degree to which the gem is free from brown or gray hues. The most desirable gemstones, which show little gray or brown, are often described as having “vivid” or “strong” color saturation.

Gemstone Cut

Colored gemstones are generally cut to maximize the beauty of their color. A good cut showcases the gemstone’s color, diminishes its inclusions, and exhibits good overall symmetry and proportion. Because gemstone color can vary, there are no hard geometrical standards when it comes to maximizing brilliance or color.

Gemstone Weight

The carat weight of a gemstone does not necessarily allow you to accurately envision the size of the gemstone. Different gemstones have different densities, they may appear to be the same size but actually have very different weights.
