For those who play jade, gambling stones are definitely not a strange word. Before the jade raw materials are cut, every gambler will be embarrassed. After all, as the saying goes, ten gambling and nine loses, so there are many people who lose their wealth. in.
A piece of jadeite material is mined from the mine and has a thick layer of skin. Before it was shipped to the China-Burma border, it was in Myanmar such as jade mine, Myitkyina, Karayang, Foreigner Street, Mandalay (Mutual City) and so on. It is necessary to go through many jade experts to carefully study and carefully polish them, and they can find out the green on each jade. The culture of the connoisseur may not be high, but the research on jade must not be underestimated. They have a history of mining jade for hundreds of years. It has been passed down from generation to generation. It is absolutely true to find green and watery parts on the jade skin. The following are the practical experiences of the predecessors for many years. I hope that you can buy jade raw materials for you. help.
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 selecting jadeite, 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 jade; the length of the water and the amount of impurities in the cracked willow, etc. Wait. 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. 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, you can point out that the part is polished and then bid.
(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 to be purchased. If the suspected spot can be scored on the jade material with a knife, find the bonding line, or use the aforementioned warm water method to test. If there is bubble overflow on the bonding line, Then this piece of jade must be glued. But those jade materials in hot water. If only the epidermis adheres to some air cells that are at rest, this is not the case, because it is caused by the air brought in by the jade when it is placed in hot water.
(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 material is less. The experienced person can see that there is not much chance of green entering the jade material without high price, so the seller is not willing to take out a small piece of jade material. show you.
