Determining value in colored gems


Color is the most important determinant of value in colored gems. It is also, too often, the principle determinant in erroneous identification because, unfortunately, most people don’t realize how many gems look alike in color. And even professionals in the trade can be misled or caught off-guard. Too often recognition and identification are based on color alone because so few jewelers and customers are aware of the large number of similarly colored stones that are available.

Until recently, the gem stones industry has promoted very few colored stones, concentrating instead on the more precious and profitable gems. But the growing popularity of the colored stones has expanded the market so that the consumers can now find that they have a choice. If you want an emerald-green stone but can’t afford a fine emerald, you might choose a green garnet (tsavorite), a green or “chrome” tourmaline, or perhaps green tanzanite (tanzanite is the blue variety of zoisite, now there is a green variety, which is sometimes call green tanzanite). And there are at least four gem materials from which to choose, no matter what color you prefer. New gems are being discovered each year, and known gems are being discovered in new colors. Increasingly, fine jewelers and designers are creating exciting pieces using the full color spectrum. It’s the wonderful time to be part of the jewelry world, and to start exploring the possibilities at local jewelers!

The four Cs of colored gems – The colored gems have four Cs of their own, its sound like an exaggeration, but not so much as you might think. Generally speaking, the finer the rarer the color, the less impact cutting, clarity, and carat weight have on the value of the gem. On the other hand, the more common the color, the more impact these other factors have.

Color is affected by many variables that make it difficult to evaluate precisely, perhaps the most significant factor is lighter, and the type of light and its intensity can affect color dramatically. In addition, color can be very subjective in terms of what is considered pleasing and desirable. Nonetheless, there has been intensive research and development in the field of color science, and experts are working to develop a viable color-grading system. Gemologists at the GIA have produced a machine called Color Master, a type of visual colorimeter, around which they have developed a color-grading system that is gaining increasing acceptance. American Gemological Laboratories has continued to develop its color scan system, and several other systems are gaining acceptance, one of the most promising new comers being Howard Rubin’s GemDialogue. Most gem pricing guide use as at least one of these systems to describe the quality of the gemstones they are pricing but problems still exist with color communication, and no solutions seems imminent.
