In recent years. People are more and more fond of antiques. The people who collect Hetian jade are numerous. In ancient times, Hetian jade was called Kunlun jade, Saishan jade, Yushi jade, Zhongshan jade, Huiyu jade, Kunyu, Zhenyu and so on. After the Opium War, the French mineralogist Demur, a scorpion robbed by Yuanmingyuan, used specimens and tested Hetian jade and jade. According to the subtle difference in hardness between the two jade, it was shamelessly named "Jade Jade" in 1863. Named Hetian jade as "soft jade", Jadeite named "Jade Jade" from then on, let Hetian jade carry the "soft jade" black pot, and still have not turned over the case, this may be that everyone does not understand the cold knowledge of Hetian jade. First, the official name is only 130 years Hetian jade has developed and utilized the “Silk Roadâ€, which has a history of more than 7,000 years, and communicates Chinese and Western cultures. Its predecessor was the “Jade Road†that transported Hetian jade. It is more than 4,400 years ahead of the Silk Road. When Qin Shihuang unified China, Hetian jade was called "Kunshan Jade" because it was produced in Kunlun Mountain. Later, it was called "Yuta Yu" because it was located in the territory of Tian. It was not until the establishment of Hetian Zhilizhou in the 9th year of Qing Guangxu (AD 1883) that it was officially named "Hetian jade". Second, the earliest Hetian jade artifacts are not in the women's tomb The earliest recognized Hetian jade artifacts from the academic circles were unearthed at the Women's Tomb of the Yin Ruins in Anyang, Henan (the late Shang Dynasty from about the 13th century to the beginning of the 12th century), and in fact should be the Xinglongtun Cultural Site of Aohan Banner in Chifeng City, Inner Mongolia and Liaoning. Dozens of jade articles unearthed from the Chahai Cultural Site in Fuxin City. Most of these jade articles are Hetian jade, dating from 7000-8000 years ago. Third, the mining volume of nearly 10,000 tons From the beginning of Xia, Shang and Zhou, until the end of the Qing Dynasty, in the history of more than 4,000 years of writing, Hetian jade produced a total of 9,968 tons, with an average annual output of 2.5 tons. Among them, in the 1900s of Xia, Shang, Zhou, Chunqiu and Warring States, a total of 3,800 tons of Hetian jade were collected, with an average annual output of 2 tons. In the 810 years of the Qin, Han, Wei, Jin and Southern and Northern Dynasties, a total of 1,215 tons of Hetian jade were collected. The average annual output is 1.5 tons; in the 699 years of the Tang, Tang and Song Dynasties, a total of 1957 tons of Hetian jade was collected, with an average annual output of 2.8 tons; during the 295 years of Qing Dynasty, a total of 1,500 tons of Hetian jade was collected, with an average annual output of 5 tons; After the founding of China, from 1957 to 1995, a total of 9459 tons of Hetian jade was collected, which is close to the total of all the mining quantities in the past 4,000 years. 4. More than 120 tremolite jade around the world There are more than 120 tremolite deposits in the world, distributed in more than 20 countries and regions (such as Russia, the United States, Brazil, Canada, Australia, Poland, New Zealand, South Korea, North Korea, Taiwan, etc., of which Canada's production is the world's number Two). However, these deposits belong to serpentinite type tremolite jade (mainly jasper, Russia, South Korea, and North Korea produce white jade), but only Hetian jade in Xinjiang belongs to non-serpentine type tremolite due to extremely special geological formation. Jade, this is one of the important reasons why Xinjiang’s Hetian jade is highly sought after. 5. Hetian jade’s resilience exceeds that of steel. Hetian jade is extremely tough, and its compressive strength can exceed steel, which is a fact that people can hardly imagine. According to scientific tests, the compressive strength of medium carbon steel (mainly used for making heavy machinery shafts, gears, machine tool spindles, bench tools, etc.) is 1600 kg/cm 2 , and Hetian jade has a compressive strength of up to 6541 kg / Square centimeter, which is related to the felt structure of Hetian jade. 6. Hong Kong and Taiwan jade merchants are early bankers The prosperity of Hetian jade is attributed to the jade merchants in Hong Kong and Taiwan. In the early 1980s, the price of Hetian jade and Kunlun jade and Russian jade was almost the same. It was the value of Hetian jade found by Hong Kong and Taiwan jade merchants. Since the late 1980s, it has been the crazy acquisition of Hetian jade seed material, making Hetian jade the most on the market. Expensive jade materials, even the current polishing process of Hetian Baiyu, were proposed by Taiwanese jade merchants. Seven, Hetian jade resources or exhausted Up to now, the global total gold reserves are 115,700 tons, and the gold that has been mined in 6,000 years has reached 171,300 tons. At this rate, gold can be used for more than 700 years; the total global silver reserves are 510,000 tons, and the next 18-23 years Silver will be mined, and by 2020 silver will be short of supply and demand. China's Hetian jade reserves are 280,000 tons, and theoretically it can be mined for about 160 years. However, because Hetian jade cannot be purified and recycled like gold and silver, and it is disposable processing, it cannot be regenerated, and resources will face in the next few decades. Depletion, this is also one of the main reasons for the rise of Hetian jade and the rising price of Hetian jade.
