The color of the jade is usually based on the color seen in natural daylight, because the color of the jade under the fluorescent lamp is slightly dim, and the color of the jade is worse. Generally, there are four main points in the color of jadeite: thick, yang, positive, and uniform.
“Concent†refers to the saturation of the color and the depth of the color. Generally speaking, the color is called the color is older, the light color is called the color is too tender, people who don't know the jade are more old and more valuable, but it is not necessarily the same. People of different ages have different preferences for jade color. Young people like to have a lighter color, and older people like to have a darker color.
"Yang" means the degree to which the color is bright. The same color can have different brightness levels. This is what we usually say is that the emerald color is very bright or the color of this jade is a bit dark. After observing the depth of the jade color, we must look at its fresh yang, because the fresh yang is the most important factor in the beauty of the jade color, so the more vivid the jade color, the higher the value.
"Positive" refers to the degree of purity of the color. When observing the jade, there is no color of other colors, it is the purest color - pure green, the most beautiful green in other conditions, the highest value.
"Smooth" refers to the uniformity of the color distribution of the jade. Since jadeite is composed of numerous tiny crystals, the color of jadeite is difficult to be uniform. The unevenness is the characteristic of jade color. The higher the uniformity of jadeite, the more green it contains, the higher the value.
The above four points are the basics for evaluating the quality of jadeite, and the color of jade is the most intuitive factor in evaluating the value of jadeite. Therefore, these four points can be said to be the key to studying the color of jade, but it is necessary to correctly distinguish these four points. A long time of jade and accumulation of experience.
