Chapter 306 Chapter 306 Professional Appraisal

"Old Wang, I'm very curious. How do you get the tests here?" Jia Sidao glanced at the middle-aged man next to him and said, "Especially the tests on jadeite. Is the analysis very accurate?" For jadeite, its texture and water head are of course very important, but the carving process and the artistic conception of the work are equally important.After the trip to Yunnan and Jieyang, Jia Sidao has a deeper understanding of the carving of jade works, not to mention that Jia Sidao is still learning the art of carving. Therefore, after coming to the jewelry and jade testing center at this moment, what I want to know is undoubtedly starting from the jade group that Jia Sidao is most familiar with!

Facing Jia Sidao's inquiry, Lao Wang didn't show any surprise on his face. On the contrary, he was still very energetic. He adjusted his glasses and said, "This is Naturally... The testing methods that our jewelry and jade testing center needs to do are naturally very different from the methods of identifying jewelry on the market. Especially in terms of jadeite and nephrite, the jadeite industry in the market In most of them, people can judge whether something is authentic based on experience and simple instruments. In our testing center, in addition to the simple judgment like in Jade Store, each piece needs to be tested. All the parameters of the emerald have been detected, and on this point, I think, you should be able to understand it!"

"Well, I can understand this." Jia Sidao nodded upon hearing this.If not, what is the use of so many precision instruments in the testing center?If one of the instruments is not used during testing, I am afraid that these sophisticated instruments are just decorations.Moreover, after comparing the parameters of the jade brought by the customer with the parameters of the real jade through the detection of the instrument, it is clear at a glance whether it is true or false, which is more convincing. "However, except for jadeite, other jewelry and jade are also produced according to this process?" Jia Sidao asked.

"Almost. Basically, the general process here is like this. First of all, you need to give registration numbers to all the delivered items, and take pictures one by one for the record, so as not to be confused when the time comes, or simply be taken by someone. If such a thing happens, it not only shows that there are loopholes in our management, it is also an irresponsible behavior for customers!" Speaking of this, Lao Wang also looked at Jia Sidao, seeing Jia Sidao showed a clear look, and the smile on his face became more kind. The industry of jewelry and jade appraisal is very small, and there are not many people who know it.Moreover, just like the "Jewelry and Jade Testing Center" in the provincial capital, there are only a handful of similar institutions in the whole province.Once there is any falsification, or theft and fraud, it will soon be publicized in the circle.

Then in this circle, he will become a street mouse and everyone shouts and beats him. This is not like identifying the wrong nature due to some negligence during the detection process.If it's just a wrong identification, it won't have much impact on other people in the circle.Like some famous experts, when appraising an antique, they are not 100% sure.However, these famous experts, because of their reputation, not only will not admit their mistakes, but on the contrary, they will insist on their original appraisal results. Anyway, most of the antique business is just echoing what others say, and it is very chaotic.Generally, Tibetan friends who are a little bit more knowledgeable will not approve of their rhetoric in their hearts just because of the appraisal of a certain expert!Generally, you will keep some of your own views on the antiques in your hands!

Jia Sidao can be regarded as having really stepped into the antique industry, and he naturally understands these small and small ways!Not to mention the "experts" in the antique market, but in some programs broadcast on the TV station, those antiques that have been appraised by the experts, let alone the authenticity, the value estimated by the experts alone has a certain value. A lot of moisture! Jia Sidao couldn't control this, and felt that he had nothing to do with those so-called experts, so he naturally treated it with an "entertainment" attitude. "And after registering the sent jewelry and jade, the next step is weighing to determine the specific gravity of these jewelry." Lao Wang said with a smile, "Many fakes can show their original shape in this step. You know, different substances have different densities, so let’s say it’s jadeite. Don’t look at most jadeites, they are all very bright and precious, but we have received many What about the emerald ornaments made of gum and the like; then, we can observe with the naked eye, or with the help of a magnifying glass or a microscope, to further judge the authenticity of the identified jewels. There is color in this aspect, right? Dyeing and the like; and then use various sophisticated instruments to do a parameter test..."

While talking, Jia Sidao and Lao Wang had already reached the door of a laboratory. Jia Sidao turned his head and glanced at Lao Wang, and Lao Wang walked to the door as Jia Sidao wished, looked in from the glass window installed on the door, and then knocked on the door. Someone opened the door inside, and Jia Sidao followed Lao Wang into the laboratory together! While walking, Lao Wang explained: "Xiao Jia, there are quite a few professional instruments in our testing center. Come on, let's take a look around in this laboratory first." Jia Sidao looked around and saw that there were several staff members in the laboratory, who were testing something.Because of the distance, and because of the cover of the staff's hands, Jia Sidao still couldn't see clearly.However, only the instruments in the laboratory.Where the eye can see, there are gem refractometers, gem microscopes, gem polarizers, gem beam splitters, infrared spectrometers, etc., all kinds of gadgets that Jia Sidao had only seen in books or on the Internet before.

It really made Jia Sidao wish to have a few more pairs of eyes! Xu Shi saw Jia Sidao's curious eyes.Before he had walked a few steps, Lao Wang took Jia Sidao to a staff member, pointed to the instrument that the other party was testing a ruby, and said: "The laboratory is equipped with an infrared spectrometer, a gemstone microscope, etc. , spectroscope and other advanced instruments, through which to observe the waveform diagram of the gemstone, the color of the spectroscopic and other data, and then conduct an overall analysis, and compare it with the basic parameters of the gemstone in the computer, so that it can be more accurate come to a conclusion."

"Then the one in front of me..." Jia Sidao looked at the instrument, and asked hesitantly, "It should be an infrared spectrometer, right?" "Yes!" Pharaoh replied proudly, "The price of this instrument is relatively high among the many instruments in the testing center. It cost the testing center hundreds of thousands of yuan. And Its function, based on your understanding, Xiao Jia, it is very clear when you think about it." Lao Wang knew very well in his heart that from the conversation just now and Jia Sidao's performance now, Jia Sidao is not an idiot who doesn't know anything, especially when it comes to jade, he is more likely to be an expert.Therefore, when talking to Jia Sidao now, the explanation is not as clear as it was at the beginning.

Jia Sidao didn't care about this either. The infrared spectrometer in front of me can quickly and accurately detect the characteristics of some jewelry and jade through the appearance of strong absorption peaks based on the characteristics of the infrared absorption spectrum of jewelry and jade.For example, those jadeites that have been bleached and filled have nothing to hide under such an instrument. Although, in Jia Sidao's view, this kind of detection ability is somewhat similar to his supernatural ability. It is just a standardized detection, not as sensitive as supernatural power perception, which is more delicate and emotional.However, even so, not every testing center can equip such equipment and instruments.

No, after seeing these precision instruments at first, Jia Sidao regained his composure, and his eyes became much calmer.Lao Wang also took this opportunity to introduce to Jia Sidao more operation methods of the instruments and their specific uses.Jia Sidao was very satisfied with Director Chen's arrangement. Isn't the old Wang's role and his eloquent attitude a perfect tour guide for the "Jewelry and Jade Testing Center"? Of course, after visiting several laboratories, Jia Sidao naturally also got a taste of the demeanor of many staff members in the testing center when testing jewelry.Jia Sidao couldn't bear to disturb their work with that concentrated appearance. "By the way, Lao Wang, I think today is still a weekend rest day. Why, there are quite a lot of staff in the testing center." Jia Sidao said, "In normal times, isn't it the testing center here? Will there be more personnel?" "Well, of course there will be a little more." Old Wang pondered for a while and said, "It's just that the work of this testing center actually depends on the season. For example, holidays or something, or to catch up with What a good day and many people are getting ready to get married. Then, in the previous period of time, relatively, places like our testing center will be a lot busy. But under normal circumstances, our testing center, People on the 20th and 30th can still be busy." "Hehe, that's good. I just visited it now, and I feel a little tired. Especially when it comes to those instruments and data analysis, it takes a lot of energy." Jia Sidao said, "If you are still busy at work, it will be too tiring." "Isn't it?" Pharaoh replied, "In our business, the most important thing is to rest. We must pay attention to our eyes, body and other health matters. Otherwise, when we are busy, each of us has to test every day. There are four to five hundred pieces of jewelry and jade.” "So much?" Jia Sidao was a little surprised.For these twenty or thirty people, if each person has four or five hundred pieces, doesn't it mean that in one day, the entire testing center needs to test nearly ten thousand pieces of jewelry? "Isn't it mainly because there are too few such testing centers, and the profits of counterfeiting jewelry and jade in the market are too high?" Lao Wang spread his hands and said, "Among our customers , not only the general consumers, but also many merchants! In general, the number of jewelry appraisals sent by merchants and consumers is roughly in the form of June 4th. The difference is that the merchants sent Almost all of them are genuine products today, but the opposite is true for those sent by consumers, most of them are fakes.” When it came to the end, Old Wang was obviously very helpless, and he let out a long sigh.Everyone knows the truth of this!Fortunately, Lao Wang has been working in the testing center for a long time. After witnessing such things for many years, there is nothing to sigh, and he quickly recovered his expression. "So, for every piece of jewelry sent for testing, our colleagues in the entire testing center have to go through it in person. Only after systematically summarizing the parameters and indicators of this piece of jewelry can the final result of the testing be determined. Issuing a certificate of appraisal." Old Wang said, "That's right, let's help those consumers check it out." "However, as far as the current jewelry and jade market is concerned, the actions of your testing center alone are far from enough." Jia Sidao said, walking out of a laboratory, suddenly saw in the corridor, There is also a promotional window, which contains some simple methods of identifying jewelry and jade, and there are many illustrations to illustrate, just like the wall stickers in kindergartens, very vivid and vivid. "Hehe, these are our colleagues who are doing it for fun." Lao Wang said with a smile, "It can be regarded as doing a little bit to purify the market. No, sometimes we will deliberately free up a little Time, choose to go to some squares and do free appraisals for everyone..." Jia Sidao remained silent, although Lao Wang's last words magnified the image of the entire testing center. Even if such an event is held, most of the time, it is sponsored by some other jewelry stores. No matter how bad it is, there are potential factors in it to enhance the image of the testing center. But it is undeniable that such activities are indeed beneficial to consumers.Just as Jia Sidao participated in the folk antique treasure appraising activity organized by Ji Yanran and others, maybe this is also the reason?As for why Ji Yanran came to the "Jewelry and Jade Testing Center" to invite experts in this field to come forward, at this moment, Jia Sidao has a solid foundation in his mind. "By the way, Lao Wang, you see, I have been visiting for so long, and I can't help but feel a little itchy. Look, do you want me to participate in the testing process?" Jia Sidao raised his hand and looked The time was still relatively early, and Ji Yanran didn't send anyone over to call him. If he continued to wander around like this, it wouldn't make much sense to Jia Sidao. Anyway, during the time just now, Jia Sidao visited almost every laboratory.Suddenly, I saw a new customer coming in from the entrance of the hall.Jia Sidao's heart moved, and he planned to try these instruments with his own hands. However, as soon as the words were out of his mouth, Jia Sidao realized that when he saw the slight hesitation on Lao Wang's face, the other party might be worried that Jia Sidao's incorrect operation would damage the instrument. "Otherwise, when I am testing, you, Lao Wang, will stand by my side and help check?" Jia Sidao hesitated and said, "In this way, there is no need to worry about any major problems." As for, Jia Sidao definitely wouldn't bring up the plan to directly apply to Director Chen. Although, as long as Jia Sidao opens his mouth, with Ji Yanran's relationship on the table, Director Chen should agree to it.However, in this way, for Old Wang, it was a great offense.If Lao Wang can agree first, Jia Sidao wants to test it himself, and he won't let the relationship between himself and the testing center become stagnant! Sure enough, after Jia Sidao's suggestion was spoken, Lao Wang, who was still a little hesitant, quickly calmed down and said, "Okay, I see, let's find someone you are familiar with, Xiao Jia." Emerald jewelry, let's test it, how about it?" "Okay." Jia Sidao was naturally happy to do so.If it is to detect other things, such as diamonds, it is not of much practical significance to Jia Sidao, regardless of unfamiliarity.However, testing the jadeite jewelry now will give Jia Sidao more confidence in tomorrow's folk treasure appraisal conference! As for how the professional "Jewelry and Jade Testing Center" appraises jade ornaments, Jia Sidao has already learned the procedure from Lao Wang just now, but after all, he also understands the procedure, right?Specifically, Jia Sidao can't understand what will happen under the detection of precision instruments. Immediately, Lao Wang led Jia Sidao into one of the laboratories, where there was already a young staff member, and in front of him, there were many jade ornaments.What kind of jade bracelet, jade Guanyin pendant, jade ring face and so on, everything is available! Just for a moment, Jia Sidao felt his heart become active.
