Chapter 292

"Yes, yes, we won't talk about it. Cousin, go on." Yu zhehan also learned to be serious.

"The so-called gambling stone is to gamble with Pu Yu. You know, it takes a lot of jade knowledge to see the advantages and disadvantages of jade through its outer skin. Today, with the development of science and technology, no instrument can detect it. I don't think it can be detected in the future. When the raw materials of jade are excavated, they are covered with a layer of rock shell. No one can tell what is inside the shell. So the process of judging jade is called "gambling stone" in the industry Of course, Du Shanshan knew that on the surface, her eldest brother and cousin seemed really nothing, but in her heart, she thought that they were laughing and staring at each other in frustration, and then she introduced them in an orderly way.

"Apart from the shape and weight of a raw stone without a window, no one can tell exactly what it is inside. There is a saying in the gambling circle:" it's hard for an immortal to break an inch of jade. " It is only after cutting that there is a real conclusion. According to their own experience and the performance on the shell, the gamblers make repeated guesses and judgments to estimate the price. If you buy it, you may cut it open with a knife. It's full of color and water, and it's worth millions of dollars. Or it's colorless and waterless, and it's worthless in an instant. That's the risk of gambling stones. " Du Shanshan walks and explains to Ouyang Xiasha.

"There are the so-called" ten major Entrances "in the original jadeite stone. The first is the gray card: its shell is variegated, mainly gray green and gray black, with different transparency and uneven distribution of water bottom, but the water is often better where there is green. There is a big difference in the size of the individual, large pieces can reach hundreds of kilograms to tens of thousands of grams. The second is Mameng (also known as black sand): black black sand with gray in the black, the bottom is generally poor, and often mixed with black silk or white fog, green basket. The third is Magang (also known as Magang): the skin is thicker, and the skin color is gray yellow or gray white; the water and the bottom are better, and there are few cracks. It is a green or full green variety with green color. It contains few impurities, and the glass bottom is common, but the yield is low. " Du Shanshan to Ouyang Xiasha serious explanation way, these years, hear eye dye, know also calculate detailed. I thought that the boss wanted to gamble. Last night, I specially reviewed these contents until midnight. I was afraid that I would lose face in front of the boss and drag him down.

"The fourth is Houjiang (also known as Kandi): it is divided into old Houjiang and new Houjiang, both of which are produced in riverbed impact sand. Among them, laohoujiang occurs at the bottom of the impact layer. The skin is thin, grayish green yellow, very small, rarely more than 0. 3kg, good water, good bottom, often full of green, high green, less fog, more cracks, the color of the finished product is better than that of the original stone (that is, coloring), and the processing performance is good, so it is an ideal material for making ring face. The leather of xinhoujiang is thicker than that of laohoujiang. It is generally about 3kg. The water and the bottom are worse than that of laohoujiang. The density is extremely low, the hardness is slightly small, and there are many cracks. The color of the finished product is not as good as that of the original stone after polishing. Even if it is full of green and high emerald, it is difficult to make high-grade jewelry. The fifth is Massa: it is a new factory, with no or few skins, light green, good or bad water and bottom. It is mainly used as low-grade Bracelet material or large ornament material. The sixth is the random dry eyes: for the new factory, no skin, good water, good bottom, white fog. It mainly produces violet and red jadeite. Generally, there are purple, red and light jadeite coexisting on a piece of material, but there are many cracks. " Said three in a row, then Du Shanshan pause, then said.

"Seventh, pagang: it is a famous pit in history, and it was first mined. Pagang skin is thin, mainly grayish white and yellowish white, with fine crystal, good seed quality, high transparency and full color; it is large, ranging from a few kilograms to a few hundred kilograms, showing various sizes of Leshi. Generally, it mainly produces medium and low-grade bricks. Laopagang is famous for producing black black sand whose shell is black and coal like, but all of them have been mined out. The eighth is to cut wood (also known as knife grinding): the skin is mostly brown gray, yellow red, generally water and low are better, but more white fog, yellow fog. It is small, usually 1-2kg. It also produces red jadeite which looks like blood and fire. It is also more precious. The ninth is zibi (also known as Zibei): the shell is mainly yellow gray, the bottom is good, there are few cracks, but there is white fog. Its products are famous for blue flower water, and a small amount of green flower materials are produced to make high-grade bracelets. The famous qiluo in Tengchong is produced in this pit. Finally, it is Longtang (also known as Longkeng): it is mainly made of yellow sand skin or gray fish skin, and its shell is thicker. Most of the water and bottom are good, green is very positive, often out of high green material It seems that the more she talks about it, the more energetic she is. Du Shanshan introduces the top ten in detail.

"What kind of jade is valuable after all?" After listening to Du Shanshan's words, Ouyang Xiasha asks straightforwardly. When Du Shanshan was talking about the top ten, she tried her best to listen, but to tell the truth, she was still in a state of half knowing. However, she didn't ask in detail. After all, she had a high-end cheating device, which was useless.

Compared with the top ten, Ouyang Xiasha children's shoes are most concerned about what jade is more valuable. If she doesn't know this, she doesn't know what's inside, and doesn't know whether they are good or bad. Then this high-end cheating device is useless.

"The eldest is really straightforward, but the Imperial Green is the best color and the most valuable green among Jadeites, also known as" grandmother green ", giving people a noble aesthetic feeling. Emperor green is a kind of unique color. Emperor green is very green and green. It drips out quickly. Boss, as long as you have seen emperor green, you will feel that kind of green. Emperor Liancheng is the best color. A lot of Jadeites are valuable because of its emperor green. " Du Shanshan said."And then?" Ouyang Xiasha then asked.
