"Lao Wang, I'm very curious, how do you get the tests here. Jia Rudao glanced at the middle-aged man next to him and said, "Especially the detection of jadeite, is it necessary to analyze it very accurately?"

For jadeite, the texture and head of the water are of course very important, but the craftsmanship of the carving and the artistic conception of the work are equally important. After the trip to Yunnan and Jieyang, Jia Rudao has a deeper understanding of the carving of jadeite works, not to mention, Jia Rudao is still learning the skills of carving.

Therefore, after coming to the jewelry and jade testing center at this time, what I want to know is undoubtedly starting from the jadeite line that Jia Yidao is most familiar with!

In the face of Jia Yidao's inquiry, Lao Wang's face did not show any surprise, on the contrary, the whole person also appeared very energetic, lifted his glasses, and said, "This is natural...... The testing methods to be done in our jewelry and jade testing center are naturally very different from the methods of jewelry identification on the market. Especially in jadeite and nephrite, in the jadeite industry on the market, most of us can directly rely on experience and simple instruments to determine whether something is genuine. And in our testing center, in addition to the simple judgment like in the jadeite line, it is also necessary to use each piece of jadeite for testing, and all the parameters are detected, in this regard, I think, you should be able to understand!"

"Well, I can get that. Jia Rudao nodded when he heard this. Otherwise, what is the use of so many precision instruments in the testing center? If not a single instrument is used during testing, I am afraid that these precision instruments are just decorations. Moreover, through the detection of the instrument, the jadeite brought by the customer is compared with the parameters of the real jadeite, and it is clear whether it is true or false, which is more convincing.

"However, apart from jadeite, do other jewelry and jade follow this process?" Jia Yidao asked.

"Pretty much. Basically, the general process on our side is like this. First of all, you need to give the registration number of all the things sent over, and take pictures one by one for the record, so as not to be confused at that time, or simply be taken advantage of by someone to drop the bag. If such a thing happens, it not only shows that there are loopholes in our management, but also an irresponsible move for customers!" Speaking of this, Lao Wang also looked at Jia Nidao, and saw Jia Nidao's expression, and the smile on his face became more kind.

In the identification of jewelry and jade, the circle itself 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, as far as the province is concerned, there are only a handful of such similar institutions. Once there is any fraud, or theft and fraud, it will soon be publicized in the circle.

Then he will be in this circle, and he will become the point where everyone shouts and beats the rats crossing the street.

This is not like identifying the wrong nature due to an oversight in the process of testing. If it's just a misidentification, it won't have much impact on the rest of the circle. For example, some famous artists, when appraising an antique, are not 100% sure. However, these famous artists, because of the relationship between fame, not only will not admit their mistakes, but on the contrary, they will also insist on their initial appraisal results.

Anyway, most of the antiques are crowded, and it's very chaotic. Most Tibetans who are a little more knowledgeable will not approve of their statements in their hearts just because of the appraisal of a certain expert! Generally, they will retain some of their own views on the antiques in their hands!

Not to mention the "experts" in the antique bazaar, in some of the programs broadcast on the TV station, those antiques that have been identified by experts, whether they are true or false for the time being, just the value estimated by the experts, but there is a lot of moisture!

Jia seems to be unable to care about this, and he feels that he has nothing to do with those so-called experts, so he naturally treats it with an attitude of "entertainment".

"After registering the jewels and jade, the next step is to weigh them to determine the proportion of the jewels. Lao Wang said with a smile," A lot of fakes, in this step can show the original shape, you know, different substances, their density is not the same, let's say it is jadeite, don't look at most of the jadeite, are very bright, are also treasures, but, we have received a lot of gum and the like, shaped jadeite jewelry; then, we can also use the naked eye observation, or with the help of a magnifying glass, or a microscope, to further judge the authenticity of the identified jewelry, this aspect has color, whether it is dyed or not, and then with the help of a variety of precision instruments, to do a parameter detection……”

As he spoke, Jia Rudao and Lao Wang had already walked to the door of a laboratory.

Jia Nidao turned his head and looked at Lao Wang, and Lao Wang also walked to the door as Jia Nidao wished, looked inside from the glass window installed on the door, and then knocked on the door, and when someone inside opened the door, Jia Nidao followed Lao Wang and entered the laboratory together!

While walking, Lao Wang also explained: "Xiao Jia, there are a lot of professional instruments in our testing center. Let's take a look in this lab first. ”

Jia Rudao looked around, there were several staff members in the laboratory, who were testing something. Because of the distance and because of the obstruction on the hands of the staff, Jia Rudao couldn't see clearly. However, light is an instrument in the laboratory. Everywhere you look, there are gem refractometers, gem microscopes, gem polarizers, gem beamscopes, infrared spectrometers, etc., all kinds of things that Jia Yidao has only seen in books or on the Internet before.

It really makes Jia Yidao, I can't wait for a few more pairs of eyes to come out!

Xu saw Jia Yidao's curious eyes. Before he took a few steps, Lao Wang pulled Jia Rudao to the side of a staff member, pointed to the instrument that was testing a ruby, and said: "The laboratory is equipped with advanced instruments such as infrared spectrometers, gem microscopes, and beamsplitters, through which the waveform of the gemstone, the color after spectroscopy and other data can be observed, and then an overall analysis will be carried out, and the basic parameters of the gem in the computer can be compared with the more accurate conclusions." ”

"Then the ...... in front of you" Jia Rudao looked at the instrument and asked with some hesitation, "It should be an infrared spectrometer, right?"

"Yes!" Lao Wang replied proudly, "The price of this instrument is relatively high among the many instruments in the testing center, which costs hundreds of thousands of yuan in the testing center." And its function, judging from Xiao Jia's understanding, I think about it, it is also very clear. ”

Lao Wang knew very well in his heart that judging from the conversation just now and Jia Nidao's performance now, Jia Nidao is not a chick who doesn't know anything, especially on jade, and it is more likely that he is still an expert. Therefore, when I talk to Jia Yidao now, it is not as clear as it was at the beginning.

In this regard, Jia Yidao didn't care about it.

The infrared spectrometer in front of you can quickly and accurately detect the characteristics of some jewelry and jade according to the characteristics of the infrared absorption spectrum of jewelry and jade, and through the appearance of strong absorption peaks. For example, those jadeites that have been bleached and filled are under such an instrument, and there is nothing to hide.

Although, in Jia Yidao's opinion, this kind of detection ability is somewhat similar to his ability, but it is just a standardized detection, and it is not as delicate and emotional as ability perception. However, even so, such equipment and instruments are not available in every testing center.

No, after the initial surprise of seeing these precision instruments, Jia seemed to come to his senses, and his eyes became much calmer. And Lao Wang also took this opportunity to introduce more ways to operate the instruments and their specific uses to Jia Rudao. Jia Rudao was very satisfied with Director Chen's arrangement.

Isn't the role of this old king, and the eloquent gesture, just a qualified tour guide of the "Jewelry and Jade Testing Center"?

Of course, after visiting several laboratories, Jia Rudao naturally also appreciated the demeanor of many staff in the testing center when testing jewelry. That focused appearance made Jia Rudao a little unbearable to disturb their work.

"By the way, Lao Wang, I think today is still a weekend off, what, there are a lot of staff in the testing center. Jia Rudao said, "In normal times, doesn't it mean that there will be more inspectors here?"

"This, naturally, will be a little more. Lao Wang pondered for a moment and said, "It's just that the work of this testing center actually depends on the season." For example, if there is a holiday or something, or if you catch up with a good day and a lot of people are preparing to get married or something, then, in the previous period of time, relatively a place like our testing center will be much busier. And under normal circumstances, our testing center, about twenty or thirty people, can still be busy. ”

"Hehe, that's good, I'm just visiting it now, and I'm feeling a little tired. Especially when it comes to analyzing data on those instruments and data, it takes a lot of energy. Jia Rudao said, "If you are still very busy at work, it is really too tiring." ”

"Not really. Lao Wang replied, "The most important thing in our line of work is rest." Be sure to pay attention to your eyes, body, and other health aspects. Otherwise, when we are busy, each of us will have to test four or five hundred pieces of jewelry and jade every day. ”

"So many?" Jia Rudao was a little surprised in his heart. If these twenty or thirty people, each of whom have four or five hundred pieces, doesn't it mean that in one day, the entire testing center needs to test nearly 10,000 pieces of jewelry?

"The main reason is that there are too few such testing centers, and the counterfeiting of jewelry and jade on the market is too high?" said Lao Wang, "Among our customers, not only the public consumers, but also many merchants! The difference is that almost all of the products sent by merchants are genuine, while those sent by consumers are just the opposite, most of them are fakes. ”

In the end, Lao Wang was obviously very helpless, and let out a long sigh. Fortunately, Lao Wang has been working in the testing center for a long time, and he has witnessed such things for many years, and there is nothing to sigh about, and he quickly recovered his look.

"Therefore, for every piece of jewelry sent for testing, our colleagues in the entire testing center have to personally look at it. After systematically summarizing the parameters and indicators of this jewelry, the results of the test can be finally determined and an appraisal certificate can be issued. ”

"However, as far as the current jewelry and jade market is concerned, the actions of your testing center alone are far from enough. Jia Rudao said, walking out of a laboratory, and suddenly saw in the corridor, there is a propaganda window, on which are written some simple methods for identifying jewelry and jade, and there are many illustrations to illustrate, just like the wall stickers in the kindergarten, which is very vivid and vivid.

"Hehe, these are our colleagues, doing things 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 spare a little time and choose to go to some squares to do free appraisals for everyone......"

Jia Rudao was silent, although Lao Wang's last words raised 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, and no matter how bad it is, there are potential factors to enhance the image of the testing center.

But it is undeniable that such activities are indeed beneficial for the majority of consumers. Just as Jia Yidao participated in the folk antique treasure appreciation activities organized by Ji Yanran and others, I am afraid that this is the same reason, and why Ji Yanran came to the "Jewelry and Jade Testing Center" to invite the identification experts in this area, at this point, Jia Yidao also has a foundation in his heart.

"By the way, Lao Wang, you see that 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 Yidao raised his hand and looked at the time, it was still relatively early, Ji Yanran didn't send someone over to call him, if he continued to wander around like this, it didn't mean much to Jia Yidao, anyway, in the time just now, Jia Yidao almost visited every laboratory. Suddenly, I saw a new customer walking in at the entrance of the hall. Jia Rudao's heart moved, and he had a plan to try these instruments with his own hands.

However, as soon as the words came out, seeing a slight hesitation on Lao Wang's face, Jia Nidao understood in his heart that the other party might be worried that Jia Nidao's incorrect operation would damage the instrument.

"Otherwise, when I am testing, Lao Wang, you will stand next to me and help check the gates?" Jia Rudao said hesitantly, "In this way, there is no need to worry about any major problems." As for the plan to apply directly to Director Chen, Jia Rudao categorically would not put it forward now.

Although, as long as Jia Rudao speaks, there is Ji Yanran's relationship over there, and Director Chen should agree to come down. However, in this way, it is a great offense for Lao Wang. If Lao Wang's side agrees first, Jia Rudao wants to test it himself, and he won't make a fuss about his relationship with this testing center!

Sure enough, just after Jia Nidao's suggestion was spoken, Lao Wang's face was still a little hesitant, but he quickly calmed down and said, "Okay, I think, let's find a jade jewelry that Xiao Jia is familiar with and test it, how about it?"

"Okay. Jia Rudao was naturally happy to do so. If it is to detect other things, such as diamonds or something, not to mention that you are not familiar with it, it does not have much practical meaning for Jia Rudao. However, if you test the jade jewelry at this time, it can make Jia Rudao more confident at tomorrow's folk treasure appreciation conference!

For how to identify jadeite jewelry in the professional "jewelry and jade testing center", Jia Rudao has just learned the procedure from Lao Wang's mouth, but this is also to understand the procedure after all?

Immediately, Lao Wang led Jia Yidao into one of the laboratories, where there was already a young staff member, and in front of him, there were a lot of jade ornaments. What jade bracelets, jade Guanyin pendants, jade ring noodles and the like, you name it!

In just an instant, Jia Yidao felt his heart come alive.
