All of Jasper

Speaking of jasper, people know a lot. From ancient times to the present, the literary records of jasper can be said to be everywhere. Generally speaking, the good jasper is worth a lot. Manas jasper can be said to be all Jasper is the most widely used and widely used in history. Mabi mainly appears as mountain material. A small amount of seed material is superior in quality to mountain material. The rare Hetian Biyu seed material is the first of all jasper, its high quality jade. Quality is irreplaceable, delicate and moist, soft and smooth, green is not eye-catching, gorgeous is not enchanting, although not as beautiful as Russia, can touch and play the effect is not a kind of jasper can meet, the current point impurities Hetian Biyu, which has little or even impurity distribution, is hard to find in Xinjiang. It is a favorite of Jasper. In addition to the preference for jasper itself, modern people have no influence on the influence of jade. The ancients have a poem: "Jasper Make up a tree high, 10,000 pieces of green silk squatting," said jasper as green willow.

Look at the cause and origin of Jasper

Jasper chemical composition: CaMg5(OH2)(Si4O11)2 Identification characteristics: Black spots in jasper (referred to as chrome spinel) are the basic characteristics of Hetian jasper.

Genesis: It is formed by hydrothermal alteration of ultrabasic rocks. Therefore, it contains elements unique to ultrabasic rocks such as nickel, cobalt and chromium. Other nephrites are not available.

From the mineral composition, jasper belongs to a kind of nephrite. The main mineral is erectite containing tremolite. It belongs to the hornblende family. The tremolite to the erectile stone similar series is close to the Yangshishi end element. . The genesis of jasper is related to the intrusion of magma marble and ultrabasic rock, which is different from other nephrite varieties in terms of genesis. Other nephrite varieties are due to the metamorphism of magma marble, and the iron content of jasper Nephrite higher than other colors. Jasper is a translucent soft green jade with spinach, which is not uniform in color and structure. It sometimes contains epidote, magnetite and chromophore. The mineral composition of nephrite is mainly composed of tremolite-positive stone, and the chemical composition is silicate of calcium, magnesium and iron, and the hardness is 6-6.5. Fine texture, grease or waxy luster, slippery. Used to make utensils or crafts. The jade craftsmanship in China is accustomed to refer to jadeite (mostly green) produced abroad.

Famous place of origin and color and texture:

Xinjiang jasper: Hetian jasper seed material and production area is Manas mountain material, and a small amount of Gobi material, Hetian jasper seed material is extremely rare high quality and high price, Ma jasper produces both seed and mountain materials, including Part of the mountain water. In view of the characteristics of jasper itself, the works with jasper as the raw material are mostly in the utensils, and the times are concentrated in the Qing Dynasty and the Republic of China. The jasper produced in Xinjiang is mainly produced by the Manas jasper mine. Since the construction of the Manas jasper mine in 1973, according to the "China Hetian Jade", the annual output of the mine is at least 1 ton and the highest is 35 tons, of which 1973 ~ In 1978, the output was large, with an average annual mining volume of about 15 tons. In 1979, the lowest was 1 ton. From 1981 to 1988, it was basically stable at an annual output of about 5 tons. Jasper is a variety of nephrite. In China, Mars County, the southern margin of the Junggar Basin, has the largest output, so Jasper is also called “Ma Na Si Yu”. The collection-grade jasper distributed in Xinjiang is mostly produced in the raw material of Hetian seed, Cele, and at the end, Ruoge's Gobi material. The texture is delicate, soft and smooth, hard and clean, the color is full, and the wearing is unbeatable.

Qinghai Jasper: Around 2000, a batch of jasper was discovered in the river terrace of the Mangya area where Qinghai and Tibet bordered China. This batch of jasper seed has good roundness and large volume, and its weight ranges from 10 kilograms to several tons. Mangyu jasper is characterized by a skin shell with a thickness of a few centimeters to a thickness of 10 centimeters. The color of the skin has a clear boundary with the flesh. The color of the jasper jasper is grayish green, with black spots, less splitting, and poor jade quality.

Canadian Jasper: Canada Jasper is mainly produced in the mountains north of Vancouver in Canada. Its hardness is about 6.5 degrees Mohs. It is a kind of nephrite. It is not only the national treasure of Canada, but also the favorite of Empress Dowager Cixi in the Qing Dynasty. . Compared with Xinjiang Manas jade, it has the characteristics of large output, more uniform texture, large block size and bright colors. Due to the supply of raw materials, China imported hundreds of tons of Canadian jasper from Canada in the 1980s and 1990s. This batch of jasper has the characteristics of large volume, less splitting and bright color. This batch of jasper makes up the raw materials of jasper in mainland China. Insufficient supply, due to the mountain material, the output of Canadian Jasper is very large, 4 to 5 tons per piece. Beijing, Yangzhou and Henan have produced a batch of jade carvings made from this material. Most of these works are large in size and complete in texture.

New Zealand Jasper: Nephrite, produced in the valley near Kumara, in the west of New Zealand's South Island, is gravel-like. The shades are often green, dark green, dark green and black, and some have beautiful spinach green (deeper than emerald, with a gray hue) and transparency is generally good. The National Museum of the United States has a gravel of New Zealand jade weighing 7,000 pounds and beautiful green. New Zealand Jasper is characterized by less black spots, but the output is average. New Zealand Jasper is mainly made by local processors into a variety of jewelry.

Russian Jasper: For Jasper, around 2000 is an important period. At this stage, Russian Jasper entered our field of vision as a very high quality variety. Russian jade origins are mainly distributed in the Republic of Buryatia, Irkutsk region, Kraskriyask region, Ural Mountains and other places. Russian jasper raw materials are in the form of primary minerals. These mountain materials are large in volume, good in jade quality, less cleft, less black spots, and more beautiful colors. A large part of them reach the "jewelry grade" jasper. These jasper are made into a large number of bracelets. Beads and handles make up for the lack of high quality jasper in China. Since 1973, there are not many jasmine products produced in Xinjiang. At present, Russian Jasper is the main raw material used in Jasper in China.

Taiwan Jasper: Taiwan Jasper is produced in the Toyota area of ​​Shoufeng Township, Hualien County, Taiwan. It is greenish, so it was once called Hualien Jade or Toyota Jade or Taiwan Cui. Taiwan jasper often has black mineral spots and green markings. Taiwan's Jasper was a major throne of handicrafts exported to Taiwan in the early days, earning a lot of foreign exchange for Taiwan. However, due to the exhaustion of resources, environmental issues, and competition issues, Taiwan Jasper has been completely stopped in 1983, forcing Taiwanese jade merchants to import from Canada, and then exporting imported Canadian jasper to Taiwan as the name of Taiwan Jasper. It is a nephrite variety of good cat's eye phenomenon in tremolite, or tremolite cat's eye, and Yangshi stone cat's eye. This type of jade has a glassy luster and is long-fibery. It is observed at least 2 cm per fiber under a polarizing microscope and 100 cm in the field. Its hardness is as high as 7.1, which is higher than the hardness of ordinary jade. The so-called opal stone, after polishing and polishing the cat's eye jade ore, will appear in the middle of a slender bright light like a cat's eye. The most common opal stone is the gold and silver gemstone. The essence is jade cat's eye jade. It is the earliest and famous in Taiwan. It has been discovered in different regions of Jasper. Hetian Biyu and different color varieties have appeared one after another, but the quantity and variety Extremely rare.

Relatively speaking, Xinjiang jasper is black, while Russian jasper is greener. Therefore, in general, Russian jasper made jewelry more beautiful than Xinjiang jasper, and Hetian's jasper seed material has a strong sense of strong color and heavy color. The best product and Tian Biyu are low in price and have a tendency to catch up with jade. The prices of the two are very different. Xinjiang Hetian Biyu seed material is more expensive than Obi, the currency Mabe is lower than Obi and Gabi, New Zealand Bi is higher than Taibi, but Taibi cat eye is more expensive than other exotic Jasper, in short, every region has its The top grade of jasper, all in the knowledge of jasper and the unique vision, the suggestion is to overcome their own hobbies, to the market recognition, the experts affirmed as the first choice, must not close the door to build a car. Because everyone has different levels of color blindness.

Jasper is used to make utensils, and some are used to produce jewelry and jade. It is also a superior choice for jade carving crafts. The texture of jasper is as delicate as dark green gelatin, and rare is rare. Most of the colored ones are impure with unevenly distributed ink spots. After the middle of the Qing Emperor Qianlong, Jasper became the jade species commonly used in the palace. They also used to draw on painting, sculpture, arts and crafts, and collected traditional practices such as Yinxian, Yangxian, Pinggong, Hidden, and Hollow, and attracted foreigners. Art influences and adapts to create and develop a jade craft with strong craftsmanship and decoration. There are distinct characteristics of the times and high artistic attainments. More common in the "gold and silver wrong", in the works of the trace of Stan.

From here, we know that the jasper that we said in ancient jade articles, the top grades are mostly from Hetian Biyu seed material, and the large jade articles are almost the origin of the Manas jasper in Xinjiang. In fact, such materials are in the jade of the early new era of China. Appeared, in the Shang Dynasty, there is a kind of green jade called green jade, which is actually a kind of jasper. However, in the jade articles of the Warring States and the Han Dynasty, jade articles using pure jasper materials are rare, most of them are still The jasper material of black spots, that is, Hetian Biyu, is obviously characterized by the times. Now it is rare in antique jade. Strictly speaking, so far, no jade articles with good jasper imitation have been found, probably because of material value. The higher reason. Now we can compare the different colors and luster that various jasper reflects on the jade, so that you can know the point, especially the ancient jade.

Look at the texture, color and fat of the modern jasper jade jade to reflect our visual impact:

The white jade collection has been deeply rooted in the hearts of the people, and it is not clear whether jasper is worth collecting a lot of people. In fact, although there is no white jade or topaz, jasper has its own collection characteristics, so there is no problem as a collectible. The main problem is to determine its own collection direction and collection path according to the characteristics of jasper.
