Now many players are paying more attention to the whiteness of Hetian jade. Some collectors think that jade should be "whiter and better." In fact, the higher the content of stone in jade, the whiter the color, not the better the quality of jade, the whiter the color.
However, this line of Hetian jade also has the saying that "the color difference is one level and the price difference is doubled", so the whiteness is still very important. Whiteness is a measure of Hetian jade, but this standard should be based on jade.
In fact, there is no clear distinction between the judgment of Hetian Yubaidu. "A thousand people in the eyes of a thousand Hamlet" are affected by many factors such as eye sensitivity, and each person's perception of whiteness will be different. Maybe you think it is white, another person will think it is blue or gray, which is very common.
The classification of Hetian Yubaidu:
Gao Bai: Relative whiteness, even whiter than the first white, can be called high white, cold white. Gao Bai is the whiteness of the material is very positive, no matter what light, it is not color.
Grease white: It is a kind of warm white. The whiteness can be one level or higher than the first level, but it must be added with the fleshy feeling. Otherwise, it can only be said to be white or white. As for meat quality, that is another topic.
First-level white: white at a glance, without a little gray or blue, without excessive red or white hands. The first grade white is that the material is basically positive white, and some are slightly reddish or very light and very yellow. First-grade white is a visually comfortable material. It is white enough and not so glaring. It has a feeling of blending with the skin.
One level and a half (1.5): One eye is white, but the color is dark, and the color difference between the palm and the palm is not obvious. The attention is dark, not gray, but it can go inside the green, with a little dim.
Second-level white: white or gray, go inside, not inside the gray, on the palm of your hand, not clear, already suffocating or dim. Secondary white is some pan-green or gray, but it still belongs to the category of white jade. Generally, the tolerance to the pan-green material is higher, and the gray-gray material is always uncomfortable even if the whiteness is better.
In addition, there is also a level of white less than one level and half white, which may bring a trace of green gas or gray, so there is a saying of flashing green and flashing gray, but if the quality of the jade is good, if it is old, it will not Too much influence the beauty of jade, but the gray is a bit regrettable, so Ningqing is gray.
