The jade in Xi 'an is basically Lantian, and the mined New lantian jade deposit is located in Yuchuan and Hongxing areas of Lantian County.
Its main mineral composition is calcite, followed by sphalerite. Lantian jade has jadeite, jet, colored jade, white marble and topaz.
Most of them are multicolored jade, with distinct colors, good color and peculiar patterns. According to the recent survey, lantian jade's reserves have reached more than 6,543,800 cubic meters.
Mainly distributed in Yuchuan Township and Hong Men Temple Township. Local folk jade craftsmen used to collect jade by hand.
The color is mainly white, but also yellow, beige, light green to green. Fine and clean texture,
Good processability. Lantian jade mined in Lantian County today has been carved into various handicrafts, such as tea sets.
Wine sets, jade pillows, jade bracelets and fitness balls are sold all over the country.
What jade does Xi An produce?
Xi's specialty is lantian jade. The specialty areas are Yuchuan and Hongxing in Lantian County.
What's the name of the jade produced by Xi 'an?
Lantian jade! !
Xi 'an, where can I buy jade?
There is an ancient poem that says, "Mermaids drop pearl-like tears into a moongreen sea, lantian jade, which is warm and sunny", which is the legendary "lantian jade".
Now there is a view that ancient lantian jade is serpentine jade now produced in Lantian County, Shaanxi Province. I have seen this serpentine jade several times, but it is no different from what we call "Xiuyu" (Xiuyu is also serpentine jade, but it is called differently because of its different origin).
I once read a book called "Talking about Stone", which recorded that the texture of ancient lantian jade was "moist and good, sinking under the stone" (that is to say, the texture was delicate and heavy), which was completely different from the characteristics of serpentine jade.
When I was studying gemology, our teacher also said that it was lantian jade now, not ancient lantian jade. So lantian jade is actually a serpentine jade produced in Lantian County, Shaanxi Province. And what jade lantian jade recorded in ancient books is, it is impossible to know. I think lantian jade recorded in ancient times should be nephrite.
Then let me introduce the characteristics of serpentine jade:
1: Tone: It has a typical light olive color (light yellow green). It is believed that serpentine was formed by olivine alteration, so there is olivine color left.
2. Feel: the feel is light, and the proportion of serpentine is relatively low (similar to that of crystal), so it won't feel heavy when held in your hand.
3. Inclusions: Like all serpentine jade, lantian jade also has dolomite inclusions.
4. Gloss: The luster of serpentine is generally not very good, and few can reach the luster of glass. Generally, serpentine has a waxy luster.
Many jade shops in Lantian County are real, and lantian jade is not a precious jade.
What kind of jade is produced in Xi 'an?
Xi' an doesn't produce jade, but Xi' an buys jade in the following places: Xiaodongmen and the west gate of the provincial capital (antique market). ...
What is Xi 'an's specialty jade?
Lantian jade.
The new lantian jade mine mined by modern people is located in Yuchuan and Hongxing areas of Lantian County. Jade is fine-grained marble, mainly composed of calcite. Jade can be divided into five types according to mineral composition and appearance characteristics: the first type is white marble. The second is light beige serpentine marble. The third is yellow serpentine marble. The fourth kind is apple serpentine marble. The fifth category is banded tremolite serpentine marble.
Who is familiar with what jade Xi 'an produces?
The most famous place in Shaanxi is lantian jade. Lantian jade is a famous jade in ancient times. As early as the Qin dynasty, it was mined to make a jade seal, and there was a famous jade. There are records of beautiful jade produced in Lantian in many ancient books before Tang Dynasty. According to records, Emperor Tang Ming ordered lantian jade to make percussion instruments for Yang Guifei. His "History of Han Geography" said that beautiful jade was produced in "Lantian Mountain in the north of Beijing (north of Jin 'an)". Later, some ancient books appeared, such as Biography of consorts in the Later Han Dynasty, Zhang Heng's Poems on Xijing, Guangya, Zhu, Yuanhe County Records and so on. During the Wanli period of the Ming Dynasty, Song said in "Heavenly Creations": "The so-called Lantian is the alias of jade in Qingling (Kunlun Mountain), which was later mistaken for Lantian in An."
Where is the famous jade shop in Xi 'an?
Jade shops with individual facades are all good. After all, they are all people around them, repeat customers, the Big Wild Goose Pagoda in Xi 'an Antique Market and the Western Market of Datang. What antiques are worn are mixed, and there are too few genuine ones, let alone the quality. After all, as a tourist city, everyone knows. I've heard of Shi Yuyuan mentioned upstairs. Very good, and the price is reasonable. It's worth a visit.
What's the difference between lantian jade and Hetian jade?
I run a jade shop in Xi 'an, and the hardness of lantian jade is not very high. There will definitely be scratches. Please take good care of them. After all, this is a gift from your grandmother.
Lantian jade is produced in lantian jade Mountain in Xi 'an. Mainly used for larger furnishings, low value, there are two colors of white and green.
Hetian jade is produced in Hotan, Xinjiang. Mainly used for small pendants and toys, the value is not much to say. It is the best jade in China, and its colors are white, white-green, dark green, milky white and even yellow. Among them, ivory and yellow have the highest value. But be careful when you buy it. Nowadays, many people use afghanistan jade to fake Hetian jade. A small Hetian pendant costs at least several thousand yuan, and all the cheap ones are fake.
Excuse me, what gems are there in Shaanxi?
Gem is the niece of minerals and rocks, and it is a special industrial raw material with complex production conditions, rare quantity, handicraft processing characteristics and high economic value. It is generally believed that minerals and rocks used as gemstones must be beautiful, wear-resistant, rare and fashionable. At present, countries all over the world have used more than 200 kinds of natural minerals and rocks to polish and process various exquisite handicrafts. Gems and their handicrafts have a special position in the national economy. Since 1970s, the price of gold has fluctuated greatly in the international market, while the price of precious stones has risen steadily. Therefore, some countries have taken gems as the object of hard currency reserves. Qinba area in Shaanxi province has good geological conditions for gem mineralization, and many kinds of gem mineral resources have been discovered, developed and utilized. 1. Geological characteristics of gemstone deposits (mineralization) 1. Overall distribution of districts and cities This area is located in the composite part of the Qinling banded tectonic system and the third uplift of the Neocathaysian tectonic system, and its geological background is very complicated. The banded tectonic system is the basic movement in this area! Structure, which has undergone complex structural changes, has formed a number of composite fold zones and metamorphic zones, controlling the distribution of sedimentary rocks and the development of magmatic rocks, as well as the distribution of gem minerals in this area. In the past, there were not many known gem minerals. Through the work, gem minerals (mineralization points) and mineralization clues of various origins have been found in different areas. The known genetic types are pegmatite type, hydrothermal type, hydrothermal metasomatism type, cold water leaching type and metamorphic type. Because of the different geological conditions in different areas, they have their own characteristics in minerals: what are the main Caledonian structures in the North Qinling Mountains? Xiaoqinling area is dominated by Archean and Proterozoic strata, with strong metamorphism and magmatic activity and superior metallogenic conditions. The main gem minerals are lantian jade (serpentine dolomite marble) in Proterozoic metamorphic rock series, serpentine jade (serpentine) related to ultrabasic rocks, aquamarine (light blue transparent beryl) and lilac purple (purple crocidolite) related to pegmatite, and snail jade (serpentine dolomite) related to altered carbonate and hydrothermal timed veins. South Qinling is dominated by Paleozoic, followed by Sinian, with complex structure and multiple stages of magmatic activity and metamorphism. The main gem minerals are Hu Qingshi and Jasper related to hydrothermal activity in Shangnan blue asbestos metallogenic belt, corundum related to metamorphism and alkaline pegmatite in Foping Sinian system, opal of ultrabasic rocks in Yangxian county, colored kaolinite controlled by carbonate formation in Lower Paleozoic in Lueyang area, and the Ankang-Baihe area is a famous turquoise producing area since ancient times, and it is still being developed now, which has certain resource potential. (2) Geological characteristics of gem deposits (mineralization)
1. Hu Qingshi and Jasper: distributed in Shuangmiaoling, Fengjialing and Yuan Dawei in Shangnan. It is located between the Xianghe-Lazhushan fault zone and the Shangjin-Yunxi-Yunxian fault zone at the eastern end of the east-west structural belt in the northern part of South Qinling. Fault structures are well developed, mainly including three groups of east-west compressive faults and NW-trending and NE-trending tensile and torsional faults. The stratum is composed of Sinian greenschist, clastic rock and carbonate rock, and Cambrian and Ordovician are distributed on both sides. The upper and lower Sinian systems are in unconformity contact, and the fracture zone along the unconformity surface and the tension-torsion faults on both sides are ore-hosting structures. Later hydrothermal activity silicified some crocidolite to varying degrees, which provided conditions for the formation of Hu Qingshi and Jasper. According to the exploration data of crocidolite, crocidolite and crocidolite are mainly distributed in the strongly silicified area of crocidolite ore body, with irregular nested and nodular output and extremely uneven distribution. In the past, blue asbestos was not delineated in the exploration process, so its content and distribution characteristics need to be further ascertained. Hu Qingshi is blue-gray, massive, opaque, smooth and dense. Appraised by the process department, it has industrial value. 2. Turquoise: mainly distributed in Baihe, Ankang and Pingli counties, with 25 known mineralization points, which can be divided into Bali-Yejiagou metallogenic belt and Baihe metallogenic belt in Ankang county. Turquoise occurs in the cracks of carbonaceous quartzite in barite ore body of metamorphic rocks of Middle-Upper Silurian. It is light blue and blue-green, delicate, hard, opaque and slightly waxy. It has been developed and applied to conchoidal bone fractures for many years.
3. Corundum: distributed in Dongyue Store, Yuanjiazhuang, Foping County. This structure is located in the south wing and the east-dipping end of the secondary short-axis anticline structure in the northern margin of Changjiaoba-Yangsidian anticlinorium, and the strata are Sinian metamorphic rocks. The exposed area of the north wing of the anticline is about 65,438+0 square kilometers. Most dikes are concentrated in the east dipping end of the anticline and run irregularly along the bedding. Mainly alkaline pegmatite veins, a few aegirine syenite veins and plagiogranite veins. Corundum occurrence ......
