Xinchang district
(Also known as Xinkeng New Factory)
⑤ The new fields are 1 1 or above famous fields such as Masachang, Su Kai, Dewey and Muluangang.
New and old factory area (also called new and old factory area)
6. Among the old and new sites, Longtang site is famous.
The most famous venues are: Old Pagan, Huika, Oyaqi, Muna, Gramo and Citongka. The jade in these yards has a large output and high quality, which is often encountered in transactions and needs to be mastered skillfully. The jades in these yards make better products than those in the new yard.
Laochangqu
Located in the middle reaches of Lu Wu, it is the earliest mining area, about18th century. It is also the largest area, the largest number and a wide variety of fields. Among them, there are 27 big ports. The most famous ports are Pagan, Huika, Oyaqi, Mu Na, Gramo and Erythrina. Jade in these fields has a large output and high quality, which is often encountered in trading and needs to be mastered skillfully. [2]
Paganchang district
The site is an alluvial or eluvial deposit located in the middle reaches of the Ulu River, and its mining time began in the first century. At present, the deepest pit has reached the fifth floor, about 30 meters deep. The blocks from the first floor are almost all yellow sand shells, the second floor is mostly red sand shells with wax skin, the third floor is black sand shells, the fourth floor is gray-black shells, and the fifth floor is white-yellow shells, mostly wax skin. There are obvious differences between blocks in the field, and the difference is not easy. Only by understanding the characteristics of each field and remembering their own characteristics can we strive for perfection and make accurate judgments. The main entrances of this station are: Laopagan, Mamuwan, Huika, Shangdangqiao, Dagudi, Chitongka, Gramo, Mengmao, Dongguo, Mana, Jiebenqiong, Molaogeng, Xiandong, Xianggong, Qiongpiao, Nanying, Yuma, Geyinqiong, Dongmo, Gramova and Paer. [2]
Houjiangchang district
Houjiang River is a tributary of the north of Lu Wu, named Kangdijiang River. Emerald mining area is distributed along the river.
Field distribution of jadeite jade
So it is called Houjiangchang District. It is also an alluvial deposit, which was mined late and had a large area in the early 16th century. This includes two areas: Houjiang and Namo. Although the two places are not far apart, the jadeite blocks produced are quite different. The blocks produced in Houjiangchang District are generally about 300 grams, with many products, excellent texture, thin upper shell and excellent humor. At present, the excavation depth has exceeded the sixth floor, about 30 meters deep. There are barriers on the third and fourth floors. The situation of the first two floors is similar to that of the old yard. The block shells in the sixth floor are almost all yellow wax shells, and the barrier after the sixth floor is thicker and the ore yield is low. The main venues are: Mo Long, Bistu, Gemulin, Padman, Gangmo, Modongguo, Modi, Jiaying, Buguedo and Geqing Monamo.
dachang district
That's Burmese, which means thunder. This field is also called a minefield, and the resulting block is called a thunderstone. The site is located in the upper reaches of Kangdi, mostly supergene mines, with poor fragmentation, many cracks, poor bottom water hardness and loose texture, and most of them cannot be cut and made. Although it is green, most of it belongs to variant stones, and its value is very low. The reason for the variation of radar stone needs to be further explored from the origin to see if the lower layer can change, hoping to produce authentic jadeite. In recent years, people gradually have a new view on this field. At the beginning of 1992, a piece of high-quality land as huge as a house was found on this site, which was like a miracle and caused a sensation for a while. The only representative outlets are Namo, Qin Lan Gang and Menglan Gang.
Small site area
This gas field is located in the south of Lu Wu, with an area of about 45 square kilometers, which is three times larger than Houjiang gas field. Because there are not many fields, people call them small fields. This is a primary mineral deposit, and the postal service has produced many high-quality jadeites, which is an indispensable part of the entire jadeite mining area in Myanmar. The deepest entrance of this field has been controlled to the fourth floor, and most of them are black blocks and waxed shells. The most famous entrances are Nanqi, Nanmo, Liu Mo, Shimo, Mohan, Nanxiong, Wuqi Palace, Nahei, Tongdong, Liu Mo and Mogdi.
Myanmar Emerald Mining Area is mainly located in the upper reaches of the Wulong River in the northwest of Meng Gong, northern Myanmar, with a length of about 250km, a width of about15km and an area of more than 3,000km2. The jadeite produced in different pits of each mine has its own characteristics and different quality. Therefore, it is very helpful to identify the pit of gambling stone (that is, the pit of jade mining) to infer the quality of gambling stone jade. There is a famous saying in the jade industry, that is, "I don't know the entrance, I don't gamble." Therefore, when buying jade stone, we must know the origin and characteristics of jade material, otherwise we will unconditionally do gambling business.
According to several related materials, this paper briefly introduces eight places where jade gambling stones must be known for reference:
Houjiang jade
(also known as Candiyu):
Both Laohoujiang jade and Xinhuoujiang jade are produced in river bed impact sand. Among them, Laohoujiang jade is produced at the bottom of the impact layer. The skin is thin, gray, green and yellow, and the individual is very small, rarely exceeding 0.3 kg. Good bottom, often full of green and high green, less fog and more cracks. The color of the finished product is better than that of the original stone (that is, the color is increased) and the processability is good. It is an ideal material for making ring surfaces.
The skin of the new Houjiang jade is thicker and larger than that of the old Houjiang jade, generally about 3 kg. The water and bottom are worse than the old Houjiang jade, with slightly smaller density and hardness and more cracks. The finished product is not as good as the original stone after polishing, even if it is full of green and high green, it is difficult to make high-grade jewelry [3].
Pagangyu
This is a famous historical pit, which was first mined. Pagang jade skin is thin, mainly gray and yellow-white, with fine crystals, good species, high transparency and sufficient color; Larger ones, ranging from several kilograms to several hundred kilograms, display music stones of various sizes. Generally, it mainly produces middle and low grade bricks. Laobagang is famous for producing black sand jade whose skin is as black as coal, but it has all been mined, and all the black sand jade seen on the market is produced in Ma Meng.
Huika jade
The shell is mottled, mainly gray-green and gray-black, with different transparency and uneven distribution at the bottom, but the water is often better where there is green. The individual size of jade varies greatly, ranging from several hundred to tens of thousands of kilograms.
Ma Meng Emerald
(also known as Wushayu)
Black sand is dark gray, and the bottom is generally poor, often mixed with black silk or white fog, and green is blue. .
Beat wood and cut jade
(also known as sharpening a knife and cutting jade)
The skin is mostly brown-gray, yellow-red, generally water and low, but mostly white and yellow fog. Small, generally 1-2 kg. This place also produces red jade like blood and fire, which is even more precious.
Mogang jade
(also known as Mugangyu)
Thick skin, grayish yellow or gray skin color; Emerald has good water quality, good bottom property, few cracks, green or all-green with green, and few impurities. Glass bottom is more common, but the output is less. 7. Self-climbing jade (also known as inferior jade)
The shell is mainly yellow-gray, with good bottom and few cracks, but there is white fog. Its products are famous for their good blue flowers and good water, and there are a small number of high-grade bracelets of green flowers and jade materials. Tengchong's famous Luo Qiyu was produced here.
Longtang jade
(also known as Longkeng Jade)
Mainly yellow sand skin or gray fish skin, the skin shell is thicker. The water and the bottom are mostly good, the green is very positive, and high jade is often produced.
Masayu
It belongs to the new factory jade, with no skin or less skin, light green, good water quality and poor foundation, and is mainly used as a low-grade bracelet material.
