A piece of jadeite is mined from the mine and has a thick layer of skin. Before being transported to the China-Burma border, such as jade mines in Myanmar, Myitkyina, Karayang, Foreigners Street, Mandalay (May of the City), etc., have to be carefully studied by many jade experts, carefully polished, they can The green on the jade is found out. The culture of the expert may not be high, but it is a hundred times stronger than the research on jade. They have a history of mining jade for hundreds of years, passed down from generation to generation. It is absolutely perfect to find green and watery parts on the jade skin. Therefore, I will introduce you to your experience over the years and hope to help you purchase jade raw materials.
The reason why jadeite is difficult to identify is good. The main reason is that there is a thick layer of skin. The door and the mouth are not completely representative of the quality of the whole piece of jade. Therefore, when choosing jade. It is necessary to study the direction of green, the amount of distribution, the degree of distribution and the partiality of the color, the positive, the rich, the light, the yang, and the color of the water from the incision and the whole piece of jade; the length of the water and the amount of impurities in the cracked willow. The green color seen from the incision, whether it can enter the inside of the jade material, how much can be entered, and the change of the green cracked willow impurities that may appear after the green is entered must be considered. But the best way is to see how much green is given (see how much green can sell and profit).
When buying jadeite, you should consider more from the bad, what to do if you want to lose money, and think less about good things.
(1) Wipe the small window on the large jade material, and see the green on the delicious mouth. But think of it, if there is a lot of green, why not cut a big piece, let us see it, and give it a good price! This kind of jade is best not to buy, or to bargain with the standard of bricks.
(2) Some jade materials have sputum mouths, fractures or cuts, and the green light is lovely with the lamp, but it is not polished. Such jade must be caused by too many cracks, poor water, green irregularity or black inside. Do not dare to polish, all the defects of polishing are exposed? In this case. It can be pointed out that the part is allowed to be polished before bidding. I think the owner will never dare to polish. I have seen a piece of color weighing 5 kilograms, one third of which is all green belt. All the suede can be seen clearly. But only in the size of sesame polishing, asking price 5 million yuan, I give the highest price of 800,000 yuan. The negotiations broke down. Finally, someone in Guangdong bought it for 3 million yuan. After Hong Kong, some people are willing to pay 5 million Hong Kong dollars to buy. The Guangdongese felt that they earned too little, so they processed their own jewelry. As a result, only 1.8 million yuan was recovered from the black inside, and the loss was as much as 1.8 million yuan.
(3) Jade materials, especially high-grade jade materials, left a lot of traces of rubbing and rubbing when the owner found green on the jade before entering the border of China. These traces are all green, and they are cleverly camouflaged with the same color of sand and glue. If a piece of jade material is visible everywhere, it should be seen how much green is given (the value of this green after the finished product). There are dozens of high-grade jade materials with artificial polishing marks.
(4) The incision or a large piece of jadeite is green and full of green. For such a piece of green, it must be carefully observed. Folk words "are not afraid of a line, I am afraid of a large piece" (referring to green). This piece of green is often caused by cutting along the direction of green, that is, parallel green. In fact, the thickness of green is only a thin layer. Some high-grade jade materials, the researchers believe that there is a high-grade interior, with a knife, everything is not good, they will be glued together and sold. At this time, the purchaser should carefully observe each piece of jade that he wants to purchase. If he finds a suspected spot, he can use a knife to score on the jade material. Find the bond line, or use the warm water method described above. If there is bubble overflow on the bond line, the jade must be bonded. But those jade in the hot water. If only the air cells in the stagnation are attached to the epidermis, this is not the case, because it is caused by the air brought in by the jade when it is placed in hot water. In this way, I have identified many bonded jadeite materials that are expensive.
(5) If the jade material has been cut and the door is opened, it is necessary to look at the piece of jade that has been opened. It is necessary to see the extension of green on the whole piece of jade from the joint of two pieces of jade. Sometimes when I bought jade, I opened the door, but I didn’t see the piece that opened. This may indicate that there is a large piece of green on the small jade piece, and the green material on the opening is less green. Experienced people can see that there is not much chance of green entering the jade material without high price.
