Five-color Hetian Jade: Twilight

Hetian jade is a treasure of the Chinese nation and has been nominated as China's "national stone." As early as in the Neolithic Age, the ancestors under the Kunlun Mountains discovered Hetian Yu and transported and exchanged them to the east and the west as a treasure and a friendship medium, forming the oldest Hetian jade transport passage “Jade Road” in China. The predecessor of the "Silk Road". In China, Hetian jade is distributed in the Kunlun Mountains in the south of the Tarim Basin. From the west of Tashkulgan County in the Kashgar region to the west, the Antarcung Mountains and the Hetianyu metallogenic belt are more than 1,100 kilometers long. Good Hetian jade seed material, shape, whiteness, skin color and run-degree are good can be called fine. The seed material is formed after thousands of years of constant grinding and scouring in the river bed. If it can receive a very good shape and less seed material, it is indeed very rare, the price is also high in the market, as the saying goes It is not very appropriate to use seeds and jade that are very beautiful in shape. When there is one, it can be carved into various kinds of exquisite devices. The same thing can also be done a lot. However, for a beautifully shaped seed material, it is recommended that the original shape of the material be retained in the form of gold or silver. The natural carving is a beautiful pendant. This kind of good material surpasses any master's masterpiece.

The Hetian jade pendant in ancient China pays much attention to the color of Hetian jade. It is not only an important symbol of quality, but also attached to a certain ideology. The ancients may be affected by the five elements of the saying. According to the distribution of colored jade by the Quartet and the Central Committee, the east is green, the west is white, the south is red, the north is black, and the center is yellow. In ancient times, the five colors of green, red, yellow, white and black were positive colors, and others were inter-color. Thus, jade is also divided into five colors.

Wang Yi's "Jade" contains jade color: "Red is like a chicken cock, Huang is like a steamed chestnut, and white is as a typographer, and ink is like a pure lacquer. It is said that it is a jade character. There are blacks, and no ones are yellow." This is to say that jade has white, blue, black, red and yellow colors, and common colors are cyan and white. Fu Heng et al. "The Map of the Western Regions" said that the jades produced by the Heyu River include: 绀, Huang, Qing, Bi and Bai. Gion Park, “The Western Regions, Wen Jian Lu” said that Ye Er’s jade was produced in different colors, including white, yellow, red, black, and blue.

The above is said that there are five colors of jade, but the Ming Dynasty scientist Song Yingxing thinks that the jade is only white and green. He said in Tiangong Kaiwu: “Where there is only white and green colors, green Chinese cuisine Jade, its Chiu Huang Yu said, all its stone sarcophagus class, the price is not under the jade, but not jade.” The ancients said that the jade is not the same, after our investigation and Daiyu actually only white, blue, ink, yellow Four-color. In addition, jasper is also produced in some areas of the Kunlun Mountains and in the Altun Mountains. It is also a nephrite, which is associated with ultramafic rocks, similar to the Canadian jasper and the Xinjiang Manas jasper, but can also be attributed to the Heyu jade range. Different colors of jade, the quality is not the same, such as "Xige Xinjiang ancient theory of treasure on the" said: "Yuyu out of the Western Regions in Lu state, there are five colors ... ... look at the white and yellow jasper." China Since ancient times, white is a symbol of purity. "Han Shu Sheng Heng Chuan": "Clear white people." So people love white. Baiyu is not only white in color, but also in texture. Deep people love it and are listed as treasures.

The colors appearing in Hetian jade can be divided into five colors.

1. White Series: There are many varieties of white jade in Hetian Yuzhong: white sheep flesh, snow white, pear white, ivory white, white, brown rice, chicken bone white and so on. Among them, white suet is the best. In the history of white jade, jade, jade king.

2. Green series: In white jade and sapphire, it is often light greenish white, light green, grayish green, and greenish to dark green in jasper. From white jade, sapphire, and jasper in order, the content of iron oxide increases as the color deepens. Jasper generally contains elements that are unique to ultrabasic rocks such as chromium, nickel, and diamond. In addition to tremolite, the jasper minerals begin to show actinolite or tremolite with more iron. Thus presents different shades of shades of green. Dark spots and jade tendons are noticeable. With a small amount of impurity minerals.

3. Yellow series: There are yellow, yellow, yellow Wax, yellow chestnut, okra, sunflower yellow, egg yellow, half-yellow yellow, yellow-yellow yellow in the topaz, among which the chestnut yellow and beeswax yellow are the upper. Other yellow times. Huang Yu is yellow and is pretty, the more concentrated and more precious, its precious value is not under the sheep fat jade, and is less common than sheep fat jade. Mostly caused by iron oxide.

Topaz 4. Black Series: Hetian jade jade (black jade) is gray, black. Black is sometimes unevenly disseminated, black spots, clouds, pure black and other colors. High quality black as pure paint. It is rare and precious. Moyu also known as black jade, or appear in the black jade sapphire, but also in the jade, white jade appears in the jade. The cause of coloration is mainly due to the presence of micro-scale graphite impurities between the tremolite particles. The degree of black is strong or weak, and there are differences in depth and distribution.

Moyu 5. Maroon series and other colors: Hetian Yuzhong is said to be sugary jade because it resembles brown sugar. Mostly purple, brown red, red blood (rare). Limonite is distributed between the tremolite grains in the sugar and jade parts, indicating that the sugar jade is formed by red color or brownish yellow due to iron oxide pollution of tremolite. Manganese oxide can be purple.

Sugar and jade to distinguish Hetian jade is good or bad: First look at the texture, the most important is the degree of sophistication and purity, with no burrowing person, bright color, rich sense, maturity is strong; second look at the shape and skin color; Finally It is to see the degree of whiteness. The key to the quality of a piece of jade is texture.
