Hetian jade identification is a very complicated matter. There is only good or bad between jade and jade, but there is no difference between true and false. To select good jade, you must understand the characteristics of various jade, and jade and other imitations. It also needs to be identified. This requires some practical experience. The following is a brief introduction to the identification points.
First, the jade is thick and thin. From fine to thick, hundreds or thousands of sequences can be arranged. The jade and jade are purely meaning here. The finer and smoother the Hetian jade, the better. From the perspective of mineralogy, different materials in Hetian jade will be infiltrated into our naked eyes, which will produce color changes and texture thickness changes, which are basically consistent with the results of the naked eye evaluation of Hetian jade. According to the particle size of mineralogy, Hetian jade is divided into three categories under the polarizing microscope: coarse crystal, microcrystalline, and cryptocrystalline.
The second is whether there are impurities. In addition to black stars, brown spots, and jade flowers, the impurities mentioned here include other substances that can be seen by the naked eye. Generally speaking, the most pure jade, and the impurities of Hetian jade, from small to large, from small to large, never Obviously obvious, there is a certain amount of more or less, of course, the lower the impurity content, the higher the level.
The third is color. Just talk about the most popular Hetian jade white jade, whiteness is the simplest and clearest, and it is also the easiest to make people go astray.
The fourth is the degree of moisture. Warmness is a kind of feeling, which is related to texture oiliness and transparency. Good moisture generally has a fine texture, good oiliness and corresponding transparency. Sheep fat jade has a high degree of moisture, because Hetian jade is present. In the gathering area of ​​the Hui Muslim herdsmen, the herdsmen pick up the most beautiful jade, which is described by their most common sheep's tail fat, which is very vivid. The moistness of Hetian jade is from dry to dry, and the grade is also reduced.
The fifth is skin color. Hetian jade skin color is generally produced on the seed material, and individual mountain water or Russian seed material also has a skin color. Hetian jade's splendid skin color is unique in the global nephrite world, and the skin color is an ornament, embellishment. It makes it even more exciting on Hetian jade, with non-replicable features.
Sixth is transparency. Hetian jade is a micro-transparent, impervious or semi-transparent. The Hetian jade flakes of 3 to 4 mm or more, if they can see the text, are too transparent. It is normal for white jade to pass through. Hetian jade's transparency and texture have little to do with, of course, under the same texture and moisture, the penetration is higher. There is a kind of slurry or stuffy material, which is almost impervious. It is no different from the difference. The permeability of Qinghai is very high, and the quality is far from the jade produced by Hetian.
