Colored gemstone pricing
Color color value in gems is the most important determinant. Also, often, mistaken identity, because, unfortunately, most people do not know how many gems look like a major determinant in color. And professionals in business or may be misleading guard caught. Often recognized and identified by color alone, some jewelers and customers are the same colored stones that are available are aware of the large number.
Until recently, some colored stones in gemstone industry is promoted, the more precious gems and instead focusing on profitability. But the growing popularity of colored stones have expanded the market so that consumers feel they have a choice now. If you want an emerald green stone, but can not afford a good page, a green garnet (tsavorite) can choose a green or "chrome" tourmaline, or perhaps green "tanzanite" (tanzanite zoisite blue variety now there is a green variety), sometimes called green tanzanite. And that at least four gem materials from which to choose, no matter what color you prefer. New gems are discovered each year has been, and known gems are discovered to be in new colors. Increasingly, fine jewelers and designers exciting full color spectrum using pieces are created.
Colorful gems four Cs
We have already discussed the four Cs to consider in choosing a diamond, but colored gems have their own four Cs: color, color, color, and color! This statement as an exaggeration, but may not sound much as you might think. Generally fine and rare color, low-impact cutting, clarity and carat weight on the value of the gem. On the other hand, more common color, and the impact these other factors.
When we discuss color, we are not just about color. Color science and color evaluation, a very complex area. But the various elements that should be factored into the evaluation of color sense, in a completely different light colored gems can start viewing.
Color of many variables that it is difficult to evaluate properly impressed. Perhaps the most important factor is light, light and color can dramatically affect the type of intensity. Also, color is very pleasing and what is considered desirable in the case can be subjective. However, there is extensive research and development in color science has been, and experts are developing a viable color grading system. GIA gemologist is produced on a machine, Color Master, is a kind of visual color meters, around which they have a color grading system that is gaining increasing acceptance called developed. American gemologist ColorScan system continued to develop its laboratories, and many other systems acceptance, the most promising being Howard Rubin GemDialodgue new people are receiving. The gem price guide, use at least one of these systems are pricing the quality of the stone they have described, but the problem still exists with color communication, and no solution seems imminent, and a system Yet the old eye and brain combination is replaced by age, coupled with years of experience in colored gems.
Color key element in describing
We always look colored gems pure spectral colors, which range pure red to pure violet brown, white, black and brown coupled with varying degrees some combination. The spectral colors seen affecting the tone of color and color classification in combination with the difficulty that these colors later, it is. For example, the white with red is present, then a lighter tone or shade of red, if black is present, a deep tone or shade. Brown, white, black, brown or a nearly infinite number of color combinations can result depending on the degree.
As a general rule, about a stone's color is pure spectral color, better color is considered; closer it comes to a pure color, rare and more valuable. For example, if we have a green stone, purer green colors are considered better. In other words, it comes close to being a pure spectral green, blue or yellow as an intention of any color (tint), having better color. There is no such thing in nature, however, as a completely pure color, color is always another color is modified by an internal quality. But the undertones so beautiful, unusual, specific colors can make the often very desirable.
