First, color.
Color is the most important factor affecting the value of jadeite, and the color of jadeite can be evaluated from the following four areas:
Purity: Purity refers to the ratio of primary color to secondary color of jadeite. Take green jadeite as an example, pure green is the best, followed by yellow or blue, and gray is the worst.
Appropriate shade: when it comes to the depth of color, of course, the thicker the better. But if the color is too thick, it will have the opposite effect and reduce the quality of jade.
Be bright: the brighter the color of jade, the more attractive it is. The more gray or black it contains, the darker the color.
Uniform: The more uniform the color distribution, the better, and the higher the value.
Second, transparency.
The transparency of jadeite affects the refraction of light, thus affecting the overall aesthetic feeling. When the light enters the transparent and delicate jade, it will reflect beautiful light, which will make people feel the crystal clear of jade and greatly increase its aesthetic feeling. On the contrary, if light meets jadeite with low transparency and rough texture, it will reflect dark light, which will greatly reduce the attractiveness of jadeite.
Third, clarity.
Cleanliness refers to the defects contained in jadeite, mainly white and black, which are caused by other minerals contained in jadeite. Relatively speaking, black defects are more ugly than white ones. The less impurities in jadeite, the better.
Fourth, cutting work.
The processing of jadeite products can be divided into two categories: light body and carving. Because the surface of the bare finished product is not covered, the requirements for raw materials are high. In addition to no cracks, the proportion of cutting work, the thickness of the product and whether it is symmetrical are also very important, which can affect the appearance of the finished jade. For example, the sliced "egg noodles" should not be too thick or too thin, and the position of the "pot" should be in the middle and the proportion should be moderate.
The evaluation of flowers mainly measures their aesthetic feeling and the fineness of carving. Usually jadeite with cracks will be carved to cover up its defects.
Verb (short for verb) crack
Patterns will greatly reduce the value of jadeite. If there is a crack in the jadeite jewelry, it may crack along the crack if it is slightly collided. Therefore, you need to be extra careful when buying jade ornaments. Generally speaking, with a flashlight, it is easy to detect the existence of cracks.
