Gemstones come in virtually any color in the spectrum and each gem can come in a variety of hues as well. Prices for gems vary depending on factors such as the gem's rarity, durability and popularity. A gem's value can be determined by many other factors such as size, clarity, cut and enhancements.
While there has been no standard set for judging the color of gemstones, many consider it to be one of the most important characteristics in evaluating gemstones. When describing a gem's color, the characteristics, which come up most often, are hue, saturation and tone.
Hue refers to the gemstone's basic color. A gem is considered more valuable if it's hue is purer. For example, emeralds should be green, rubies red and sapphires blue.
Saturation measures the intensity of a gem’s color. In essence, a stone that is free of muting tones such as gray or brown are more desirable. The saturation is the characteristic is referred to when the gem is described as dull, strong or vivid.
Tone measures the depth of color and evaluates the color's lightness or darkness. The terms that jewelers’ use is either very light, light, medium light, medium, medium dark, dark or very dark.
Because gemstones form under unique circumstances, each individual gemstone is comprised of a combination of trace minerals, which create a unique set of identifying marks or inclusions. Inclusions will not necessarily detract from the beauty or desirability of a colored gemstone.
When considering a colored gemstone's clarity, you should measure your expectations against the standard for that variety of gemstone. Some varieties of colored gemstones, such as aquamarine, blue topaz, and citrine, have naturally fewer inclusions while other gemstones, such as emerald and ruby, tend to have a higher rate of acceptable inclusions.
Clarity is an important factor in comparing quality colored gemstones. Even opaque opals can have milky inclusions that will affect their iridescence and color play. In general, the best values are available in gemstones that are moderately included. Exceptional gemstones with few or no inclusions are available, but they can command extravagant prices.
As there is no generally accepted grading system to define a gemstone's cut, colored gemstones will usually have a table, crown, girdle, pavilion and culet and its cut refers to the proportions and symmetry of the stone.
The goal for a gemstone's cut is unlike that of a diamond where the ideal cut maximizes brilliance. For gems, a high quality cut will expose the fewest inclusions and presents the most even color.
A well-cut gemstone is symmetrical in all dimensions and reflects light evenly across the surface and provides good brilliance.
A gemstone's saturation will also help to determine how it should be cut. A gem with a more saturated color can allow for a shallow cut to permit more light to penetrate while a less saturated gem can use a deeper cut to increase its vividness.
The process of enhancing a gemstone to bring out its beauty is a generally accepted practice and is defined as any treatment other than cutting or polishing that improves its appearance, durability or availability. There are many methods of enhancing colored gemstones. We describe the most common enhancements below.
The application of heat to enhance the color and/or clarity of gemstones has been common practice for centuries. It is part of the standard polishing and finishing process for many colored gemstones. As such, the jewelry industry and the American Gem Trade Association accept this enhancement process. The enhanced color and/or clarity of heat-treated gemstones are permanent.
Fracture filling is the process of filling of a gem with oil or other materials, to improve appearance. This process began centuries ago by gemstone merchants who found that immersing emeralds in oil or waxes made them look clearer to the unaided eye.
