Chapter 631 I am an expert Zhang Wufeng naturally knew that this test of luck was actually set up by her and Lao Fang to find a person with great luck to help her complete her trip to Myanmar and resolve the disaster. So, he nodded calmly. Although Zhang Wufeng could feel that the inside was purer and greener than the outside, and the green was pleasant. It was indeed imperial green, and the value could reach more than 16 million, but Zhang Wufeng did not gamble anymore. Money, these are enough. "Well, this is no problem, although I am sure that the quality inside this stone should be higher! But Miss Sun wants to buy it, so I will sell it to Miss Sun!" "Haha, you are indeed very good!" Miss Sun smiled, He praised me again, and then without even frowning, he wrote another check for twelve million. Zhang Wufeng took it over politely. "Miss Sun, do you want to continue wiping?" the old man asked with a smile. "Well, of course I have to continue. If it is really imperial green, it will just make a set of jewelry." Miss Sun said with a smile. Zhang Wufeng sensed the business card in his pocket. The woman named Sun was named Sun Feifei. The light yellow business card with an ancient style only had a name and a phone number starting with 136, and nothing else. Seeing this familiar business card again, the tenderness in his heart was still hard to let go, but when he felt the lovely girl beside him, Zhang Wufeng no longer hesitated. ¡ The old man smiled, changed the direction of the stone, and then wiped it a few times. After wiping off the stone chips, he frowned slightly, and then wiped it a few more times, and a white line appeared. "Here, the flowers at the bottom are not likely to be imperial green." The old man pondered, but he still said it. Miss Sun was slightly disappointed, but she didn't care. She continued: "The green on the front is not bad. Master, please continue to rub it and give it a rough look. If the front part is larger, it will be good for making jewelry." " Although she was a little disappointed, Sun Feifei still didn't care much. It was obvious that even if the bet failed, twelve million would still have little impact on her! At this time, many people were already talking in the hall. Obviously, this matter had caused a big enough sensation. However, as he continued to wipe, the old man's hands trembled, and Miss Sun's face clearly showed a bit of joy. It seemed that she was not happy because the bet had gone up, but because she had the imperial green jewelry. Happy. "Emperor green, it is indeed imperial green. Although it is not big, its value is worth 16 million! Miss Sun, congratulations!" The old man said with a smile. At this time, there is no need to wipe it anymore; I wiped it off slowly and carefully. This cannot be solved in a short time. "Haha, thank you Master, and also thank you little brother Zhang Wufeng. I wonder if little brother has time to have a meal? I'll invite you to the Fuye Hotel for dinner!" Sun Feifei said very excitedly. At this time, she showed her expression The cute side of a girl comes. Zhang Wufeng has a very sharp eye. He could tell at a glance that this was just a young girl. Although she was dressed fashionably and maturely, she looked about twenty-four years old. She casually called her "little brother" not because of her age. It's just a sign of high status. "Well, okay, whenever Miss Sun has time, call me Old Fang and Uncle Fang. I will definitely bring my girlfriend with me." Zhang Wufeng said with a smile. At this time, in front of Sun Feifei, he deliberately hugged Suru. This made Suru extremely embarrassed and also made Sun Feifei feel unexpectedly confused? What is he doing? "Okay, that's good. Well, I will contact you." Sun Feifei said with a smile. "Haha, you know, I have wanted a set of imperial green jewelry for a long time. I am very happy to have the opportunity to realize it this time. Thank you for agreeing to have dinner together, thank you!" Sun Feifei said with a smile, and she also showed her face to Zhang Wufeng A gentle smile. Zhang Wufeng's eyes paused for a moment, because he could see Sun Feifei's big eyes through the sunglasses, so he knew her beautiful appearance, so this smile was really heart-warming, and Zhang Wufeng almost instantly thought of Feifei when she turned around The moment he left and burst into tears, his heart trembled slightly, but it only took him a moment to regain his composure. ¡ On the way, Suru still seemed a little unbelievable. Just made 14 million? "This is too" "Suru, now, let's buy a car, and tomorrow we'll buy a house, a house of our own, do you agree?"?Zhang Wufeng hugged Suru. After he came out, he was not afraid of being robbed by others. He was once afraid, but now he has nothing to fear. The soldiers came to cover up the water and the earth. Now, he is not a person who can be stepped on casually. "Okay, it's just that after having so much money all at once, I feel a little uneasy, like I'm in a dream." Suru said softly. Zhang Wufeng smiled and said: "It's not a dream, it's real. How about I kiss you and you'll know. You feel relaxed looking at this gambling stone, but for this gambling stone, I spent nearly two years day and night." "Ah - so you've been studying this for the past two years?" "Well, I'm an expert." "The taxi is coming," Zhang Wufeng said to the taxi driver. The address of the hotel, and then sat in the back seat of the car with Suru. "Wufeng, have you studied the stone gambling thoroughly?" "Yes, well, in order to avoid you worrying, I will explain some knowledge to you casually, so that you can rest assured." "Okay, you tell me, I I have read relevant books and have some understanding, but I only scratch the surface." Suru said with a smile. Snuggled in Zhang Wufeng¡¯s arms, it felt very warm and comfortable. "The so-called gambling stone is actually some primitive natural accumulation. Let's start with jadeite. Let's talk about high-end jadeite first. Let's put it this way, the color must first have a certain concentration. It is dark, but deep but not dark. , the color is bright and pure green, that is, the color is not gray and the uniformity is good. In addition, the texture is relatively fine and the transparency is relatively good, that is, the glass ground. Of course, even if they are all called Laokeng species, their quality is relatively different. Some are more transparent, some are slightly less transparent, so the value is also different, but in any case, as long as it is a more attractive jade variety, it is often used for high-end jewelry. As for the reason why it is called Laokeng species, it is. There is a reason. Chinese people believe that older jade, including jade, is the most beautiful, with darker color and better transparency. In addition, jade with this texture is mostly found in secondary deposits in Myanmar, and Myanmar jade is secondary. Raw ore deposits were mined earlier, so they are called Laokeng and Xinkeng. They are actually divided according to the year in which jadeite was discovered and mined. From a geological point of view, the geological age when they were formed underground. They are the same. Secondary deposits deposited by rivers were deposited by rivers in the Quaternary period. It can be said that they were formed later in time. Some experts have discovered from long-term practice that the deposits in the "Laokeng" are. It is a fact that jadeite is of better quality and has more moisture. The jadeite found in river sedimentary deposits is of better quality, with high color, fine texture and good transparency. There is a reasonable explanation for this situation from geological theory. These phenomena that exist in jadeite deposits also exist in other gemstone deposits, such as diamonds in placer mines, which are of better quality than primary ore deposits. This is because primary ore deposits actually contain various ores of varying qualities, which are transported by water flow. , deposited into secondary deposits, some jade with poor quality, such as cracked, coarse-grained, loose structure, and impure jade will be naturally sorted and eliminated, and the ones that are finally retained in the river bed will mainly be of texture. Tighter and finer-grained jadeite. This kind of jadeite is often more transparent, but it is not caused by the intrusion of water. Water cannot enter the jadeite crystal. It is because of this relationship that the jadeite from Laokeng is of better quality. The outer layer of skin is due to the oxidation and hydrolysis of nature when jadeite is exposed to the surface, causing some of the iron and manganese contained in it to precipitate and become a kind of iron oxide or manganese oxide that adheres to its surface, forming a shell. Just like a knife that is not used often, its surface contains oxidation and rust. It can be said that the jade in the "old pit" is of better quality, but there are also better quality jade in the new pit, but it is relatively small. The results of the sorting! Now, do you understand?" Zhang Wufeng said confidently. He didn't understand it before, but now, he really understands it. "Well, I understand, that's it. I have read relevant books, and I generally remember some of them, and they seem to say the same thing." "Yes, books are actually summaries of the essence of previous research, just like the identification of jade. Similarly, put the jadeite under a fluorescent lamp and observe its color change. There is no change in the jadeite a and c. The jadeite b has fluorescence and turns white. The jadeite c has been dyed, so its color is distributed along the cracks and is unevenly distributed. Observe carefully. It can be seen with the naked eye. The so-called A-grade jade is natural jade that has not been chemically treated and has natural color and effect. B-grade jade is bleached jadeite that has been cleaned and injected with strong acid. Soaking and cleaning can help improve the transparency and color of jadeite.Jade, dyed jade, is jade that has been artificially colored, usually with organic dyes or inorganic dyes. b+c jadeite is jadeite that has been treated with strong acid cleaning, glue injection and artificial coloring at the same time. In terms of evaluation, color is the first factor in evaluating jade. The standards for good color are: positive, dense, yang, and even. ¡°Positive¡± refers to the range of hues, which is determined according to the ratio of the primary color to the secondary color, which means it should be pure green and should not be mixed with other colors. For example, oil blue is often mixed with oil blue, and the value will be reduced. Dense refers to the depth of the color. For emerald green, the best concentration is between 70% and 80%. 90% is already too thick. Yang refers to the brightness of the color of jadeite. The brightness of jadeite is mainly determined by the proportion of green and black or gray in jadeite. If the proportion of green is high, the color will be bright; if it contains too much black or gray, the color will be dark. Experts often use vivid methods to express the brightness of the color. For example: boxwood green, parrot green, onion green, pepper green, all refer to the colors of the bright sun. Spinach green, oil green, river green, and black green refer to dull dark green colors. The brighter the jadeite, the higher its natural value. Uniformity refers to the uniformity of the color distribution of jadeite. The color distribution of jadeite is generally uneven. It is not easy to obtain jadeite with uniform color distribution. The best color of jadeite should be pure green, with a green concentration of 70%-80%, bright color, and even color distribution. This type of high-end jadeite is commonly called Laokeng species by experts. As for Laokeng Zhong, I explained it to you before. "
