In the Ming and Qing Dynasties, people referred to white jade, only refers to Xinjiang Hetian Baiyu; now, the white jade that people see, in addition to Xinjiang Hetian jade, there are white Johor Bahru, Miyu, Dushan jade, Qinghai white jade and South Korea, Russian white jade and so on.
Discriminating materials: White jade usually has seed and mountain materials. The seed material is the original ore after weathering or crustal movement. After the relocation of the trillions of years, it will go to the riverbed. It has been tempered, collided and washed for thousands of years. Smooth, pebbly jade, inorganic organic matter and various mineral elements in the river water participate in the impact of honing. Over time, the tiny gaps in the white jade skin leave marks, which is the "face" of the seed material - osmanthus skin, rust spots .
The mountain material is a primary or a white jade buried in the rock mass. It is generally irregular in shape, with sharp edges and corners, and the texture is not as dense and fine as the seed material. The crack is slightly more than the seed material. White jade is characterized by its "whiteness", and white must conform to its own texture to show the natural and carved beauty. The traditional methods of "whiteness" are: sheep fat white, pear white, snow white, fish bone white, ivory white, chicken bone white, brown rice white, gray white, gray gray white, etc., among which the seed material is white fat (texture like sheep The grease is made of a complete material with a leather case, and the higher the weight of a single rough stone, the higher the value. There is no doubt that white jade is the leader in jade.
Look at the material: Hetian jade is also called soft jade hornblende. Observed under the microscope, it has a fiber-transformed interwoven structure with a hardness of 6-6.5.
Hetian jade has a variety of colors, and white jade is the most precious. Hetian Baiyu has the distinction of seed jade, mountain water jade (or Gobi beach jade, new mine jade) and mountain jade (mountain jade). The white jade in the seed jade, "body like gelatin, fine light blue" texture is warm and fine, almost no visible fiber intertwined with the naked eye, white as cut fat, its characteristics are "white, transparent, fine, moist" It is the best in jade.
The mountain jade is not as moist as the seed jade, the color is slightly grayish, and it is more dry, and some also show cracks. Good mountain jade is also white and red. But white is as little as fat. Russian white jade and Qinghai white jade have only appeared in the international market in recent years. Their color is similar to that of Xinjiang white jade, but it is not warm, and the lights are on the sidelines. The general structure is loose and has a glassy feel. Good Russian white jade, with a high whiteness and a slight oiliness, is very popular among collectors. South Korea white jade, its color is white, and the lights are on the sidelines, and the impurity structure is also loose.
Pick Xinjiang Hetian white jade, in addition to the color, but also pay attention to the presence or absence of flaws. At the same time, you need to pay attention to its skin color. Some Hetian jade also carries a little "osmanthus skin", "jujube red skin", "autumn pear skin" and "crow skin". This is also a major feature of Hetian jade. When making jade, the artistic value will be greatly improved, and the collectors can add a taste.
Sight type: jade does not mean. Each jade has its shape. When choosing, you should pay attention to the shape of it is not like, completely incomplete, with or without art. The better the jade is used, the thinner the shape and the higher the value. Some jade articles have defects and cracks, some are raw material factors, and some are artificial damages.
Distinguishing the ornamentation: People wear jade ornaments, and they all emphasize the ornamentation. Because the ornamentation has its specific meaning, or Xiang, or ward off evil, or blessing, or birthday, or elegant literati atmosphere, or rich and rich, or small and exquisite, should be clearly expressed.
Exploring work: the industry calls it "work." "Work" is the engraving process. When choosing a jade, "work" is very important. "Work" is good, which means that the carving technique reaches the level of perfection, and the artistic ingenuity can be better expressed from the works. The characters and animals are vivid and the lines are smooth. If the "work" is poor and the pattern is not satisfactory, it is not acceptable.
Hetian Baiyu has a history of nearly 8,000 years in China. It discusses the development history of Chinese society, has a profound understanding of Chinese traditional culture, and has rich historical and cultural values. Modern jade works inherit the traditional Chinese jade ornaments culture. Traditional jade carvings such as â€œFulu Shuangquanâ€, â€œFushou Sanduoâ€ and â€œKirin Sending Childrenâ€ are still popular among people; they are constantly innovating in the craftsmanship of carving. The development, the characters and the characters, flowers, birds, beasts, etc., show the exquisite modern craftsmanship.
Xinjiang Hetian Baiyu has been mining for a long time since the Shang Dynasty. The output is getting lower and lower, and the price is skyrocketing. Especially the sheep fat white jade, due to its scarcity and non-renewable resources, its value will be immeasurable in the near future. Good quality white jade, fine texture, small gap between particles, it is not easy to enter impurities, so it will not change color. The white jade with poor quality has loose texture, large gap between particles, and easy to enter impurities, so it will change color.
