Chapter 307 Treasure Appraisal Activities

After explaining to the staff, Lao Wang started to pick up a plate with a number on it from the staff, came to Jia Sidao, and said, "Xiao Jia, since you want to participate in the test in person, one or two pieces, it is probably not interesting. Why not just check the things in this plate with a number."

"It's OK." Jia Sidao was naturally happy. As long as he had time, it would be fine for Jia Sidao to test more jewelry and jade here. He couldn't help but say, "But if I do this, I won't disturb your normal procedures testing work, right?"

"No, no." said the young staff member next to him. "Anyway, when we test ourselves, we should first classify the things, and then similar things will be arranged in sequence before we can go through inspection by different instruments."

"So, Xiao Jia, you can come and help test some jewelry and jade together. For Xiao Li, it has helped him reduce his work burden a lot." Lao Wang smiled and said, "How is it? Do you have confidence?"

"Of course, there is confidence. However, I still expect Lao Wang to keep a close eye on me. Otherwise, I wouldn't know how to use these instruments." Jia Sidao said politely and looked at the plate in Lao Wang's hand. In addition to some jade jewelry, there were other things like ruby ​​rings on it!

At this moment, Jia Sidao did not hesitate and chose a jade bracelet on the plate. He picked it up and weighed it. With the observation of the naked eye, Jia Sidao could tell that such a bracelet should be of the texture of the winter melon. There was a hint of green floating on it. It was not good, but it was still a natural jade jewelry! There was also an jade Guanyin pendant. When Jia Sidao looked at it, he found that the texture was actually ice-like. However, in terms of its color performance, it was really unsatisfactory. The carving skills made Jia Sidao feel it.

Of course, the evaluation of this jade Guanyin pendant is also based on Jia Sidao's aesthetic vision. If the value of the jewelry on the entire plate is already the best choice. Others are like another sun-green jade bracelet. When Jia Sidao saw it, he felt a little surprised. When he looked closer, he could understand that this jade bracelet should be suspected of being fake. He took it in his hand and touched it slightly and shone it in the light. Even without a magnifying glass or something, you can see the texture inside the jade bracelet. It seems a bit weird, the color distribution is not uniform, and there is no beauty.

No need to test anything more. Jia Sidao can directly characterize this Yang Green jade bracelet as a dyed C-grade jade on the market. It should be able to get it for a few dozen dollars!

Maybe he saw the expression on Jia Sidao's face, Lao Wang next to him also smiled bitterly and said, "In fact, every consumer sends such things to him, he still hopes that the things are real! Every time when they come back to get the test certificate and see their frustrated and angry expressions, we workers can only comfort them without any nutrition...."

This is no wonder that a inspector like Lao Wang has a lot of work every day. For these things that are fake, you can't directly issue a certificate that is real, right? However, some merchants send real things when they send things for testing. However, when they are sold in stores, they are a certificate and use multiple accessories. What are the tricks there? As long as you have purchased jade jewelry, you should understand it?

Jia Sidao was also very helpless.

First, I weighed all the accessories on the plate and calculated their respective proportions!

For example, the normal range of jadeite is 3.34 (+0.06~-0.09). If other jades are used in the jewelry to imitate jadeite, it will be easy to expose your feet at this level. Now, Jia Sidao saw that there were two jadeite jewelry on the plate that were sent to test, which were not real jadeites. Jia Sidao looked carefully and one of them was the most common gum in jadeite materials. This thing is very strong, and even if you hit the ground hard, it may not be able to crack it!

The other one is the texture of agate! Jia Sidao looked at it and then excluded it. This method of fraud is nothing more than the feeling of real jade when touched by hand. However, in detail, there are still many differences in transparency, texture, etc.

Seeing Jia Sidao's actions, Lao Wang explained on the side: "Xiao Jia, it seems that your eyesight is very strong. However, if it is a formal test, it is not possible to rely on personal eyes alone. You need to rely on scientific instruments to detect scientific data. When viewing, we can place things under the gem microscope to see."

As he said that, Lao Wang took over and demonstrated to Jia Sidao. While demonstrating, he said: "Although the operation of this gem microscope is extremely simple, its function is quite large. It can detect features that cannot be clearly observed by a 10x magnifying glass! Let's talk about ordinary rubies. Through this microscope, you can see various characteristics of the outside and inside of the gem, such as the inclusions, cleavage, double crystal patterns, growth lines, ribbons, etc.; or you can observe the grinding of the gem, polishing and accidental damage. Come on, Xiao Jia, do you want to try it?"

"Okay." Jia Sidao responded with a smile, and casually placed the jade Guanyin pendant on it.

However, listening to Lao Wang’s words is a feeling. At this moment, when Jia Sidao came to do the inspection and observation, his heart was shocked and sometimes another feeling. This is different from the usual time when Jia Sidao only used tools such as a magnifying glass to observe jade jewelry. The clarity at this moment makes the jade Guanyin pendant in front of him, the polishing technology on it, the carving marks on it, and even the texture of jade, almost nothing to hide!

After coming back to his senses, Jia Sidao was still thinking about what would it look like if he used such a gem microscope to observe the glass-type imperial green jade Guanyin pendant that he had carved out with his own hands?

Next, the detection procedure required is the GIC spectrometer, which has good light transmission performance, high resolution and good results. This is also one of the effective instruments used to identify the authenticity of jewelry and jade. For example, under the GIC spectrometer, those dyed jade have very different spectral characteristics from natural jade.

To be honest, mastering the use of spectroscopy is also a necessary skill for employees of jewelry and jade inspection centers. As long as you know this, most jewelry and jade will hide nothing in front of you, and the true and false will be clear. After all, different textures and the spectrum generated are different.

As for other detection instruments, such as Charles color filters, etc., it is quite easy to operate. Jia Sidao followed Lao Wang and looked at it little by little. The learners seemed to be a little back to their student days, in the experiment, and the movements in their hands were quite cautious. Fortunately, when they encountered some instruments that they could not do, with Lao Wang's demonstration, Jia Sidao did not make any mistakes.

Moreover, in Jia Sidao's opinion, the operation of all instruments is not difficult. It is nothing more than that after the results are obtained, it is necessary for individuals to master a large amount of theoretical knowledge in advance. Otherwise, Jia Sidao could not judge the quality of the tested jewelry and jade!

So in the end, Jia Sidao asked Lao Wang for advice on what kind of data and what kind of judgments he could make. Although he couldn't learn it very specifically just by just a afternoon, it was still easy to understand the approximate situation in a test.

"Xiao Jia, if you are willing to come to our testing center to work, I dare to guarantee that you can come to work alone as long as you have an internship for a week." Lao Wang said with a joke, "You have learned a lot in just such an afternoon."

"Haha, that's all you taught by Brother Wang." Jia Sidao said with a smile, "A good master has a decisive effect on my learning effect. However, it is unlikely that I can come here to work. I have some jade business on my own..."

"It can be seen." Lao Wang said with deep emotion, "Although our salary is very good, how can we compare to opening the business yourself?..." In the end, Jia Sidao felt that people like Lao Wang must be very envious of those businessmen who go into business. After all, the profits of jewelry and jade are still very objective. Of course, Jia Sidao would not really think that Lao Wang is very confident in the way of business.

Like Lao Wang, who is working in a testing center now, his job is stable, and his salary is much richer than Jia Sidao's original unit. In addition, it is like Ji Yanran came to Hangzhou this time to invite experts here to participate in a private treasure appraisal activity, which is all due to the appearance fee.

Could Director Chen go to participate alone?

While thinking, Ji Yanran finally called and said that the matter had been completed. She asked Jia Sidao if she could go back to Linhai. Jia Sidao looked at the time and found it was really late. So she went out of the laboratory with Lao Wang.

However, the moment Lao Wang closed the door, he sighed and said, "Xiao Jia, if you have time in the future, you can come here for more walks. By the way, didn't you just say that you would do some jade business by yourself? Then, you can also receive some appraisal certificates when you send it here! Our testing center is quite prestigious in the jade jewelry industry in the province!"

"Haha, that's right. It seems that I will see you again in a while." Jia Sidao replied with a smile. In his heart, he was sighing, "Although Lao Wang looks gentle, he is actually quite good at being a human being. It's good to spend an afternoon with him. This is all Director Chen's order. However, before leaving, he can still recruit business for the testing center, which is beyond Jia Sidao's expectations!

However, before Jia Sidao opened a jade shop, he really didn't expect that since all the jade jewelry were polished and carved from his own factory, then the appraisal certificate was really blank! Now with Lao Wang's reminder, Jia Sidao's jade shop is probably in a state of being ready for everything and not having the east wind, right?

...

Sitting in the car with Ji Yanran, Jia Sidao looked at the other person, but there was no tired expression on his face. Jia Sidao was also happy that this trip to the provincial capital was quite rewarding!

"Xiao Jia, why do I see your expression? It's a bit weird. Did you encounter something bad here?" Ji Yanran asked in surprise, "But, it probably won't. I know that old king too, and he should be pretty good."

"Haha, Lao Wang is naturally very good. I followed him in the afternoon and did a lot of jewelry testing." Jia Sidao said, "By the way, Miss Ji, you should have a good relationship with the jewelry and jade testing center here, right? I wondered, after my jade store opened, can you send some jewelry here for testing and then get some necessary certificates?"

Although Jia Sidao knew very well that his jade jewelry had absolutely no problem in terms of quality, consumers did not know it. Sometimes, it was still very necessary to get some certificates to make some guarantees. Otherwise, there would not be a certificate in many shopping malls, and a few jewelry would be proof of it at the same time!

"If you need a large number of test certificates, I can help a little." Ji Yanran thought for a while and nodded. The potential meaning was that if Jia Sidao just got a few certificates to comfort the customer, then Jia Sidao would just send the things over directly. Anyway, with Jia Sidao's assets, there would be no shortage of such a little money!

"Okay. I'll ask Uncle Zhou Fugui for this specific quantity at that time." Jia Sidao nodded and said, "As far as I am concerned, I really don't know how to handle it." Furthermore, the best jade in Jia Sidao's hand certainly does not require a test certificate or other certificate. What Jia Sidao wants to sell is also a high-end customer, so he can't use these at all. As for how many jade jewelry can be found in the jade store on the Antique Street, it is for ordinary groups, and Jia Sidao also needs to ask Xu Zhiguo.

"That's good." Ji Yanran probably thought of this aspect, giving Jia Sidao a feeling, as if Ji Yanran suddenly smiled at her. Her smile seemed to have a little bit of understanding and deep taste. She asked softly, "So, Xiao Jia, are you doing something else to do in Hangzhou?"

"What else?" Jia Sidao repeated in surprise. Finally, he subconsciously looked at the time on his watch, and finally shook his head, shrugged his shoulders, and said indifferently, "It should be nothing."

"Puchi!" With a sound of "Puchi!", Ji Yanran couldn't help but pursed her lips, and without saying anything, she started the car directly.

Only Jia Sidao was left behind. After looking at Ji Yanran's actions, he wondered whether Ji Yanran's words just now reminded him that he needed to see Li Shiyun?

You know, after returning from Jieyang, Jia Sidao had not met Li Shiyun yet!

...

On the night after returning to Linhai, Jia Sidao had nothing special to do. Originally, on the way back, Jia Sidao planned to call Li Shiyun and tell him that he had been to the provincial capital today. Then, because Jia Sidao did not even go to see her when he arrived in the provincial capital, he put down the phone. However, because he felt the function of the gem microscope, Jia Sidao was quite ready at this time, so he called A San and asked him to contact the helper to get one back!

In addition, I exercised my mental strength early and fell asleep early.

The next day, Jia Sidao got up very early. According to Ji Yanran's instructions, Jia Sidao first hurriedly had breakfast, and then met with Ji Yanran at the entrance of the villa area to go to the scene of the antique treasure appraisal conference. Before leaving, Jia Sidao deliberately stood in front of the mirror for the first time and sorted out his clothes! Although there were any special requirements for wearing and antique appraisal conference, Jia Sidao has always been dressed very casually, but he also needs to pay attention to being decent, right?

Jia Sidao was somewhat nervous about the upcoming TV station filming, not as relaxed and comfortable as he seemed!

When Jia Sidao and Ji Yanran arrived at the treasure appraisal event together, it was still early. Because the venue of the entire antique appraisal conference was set at the westernmost end of the antique street, there was an empty courtyard next to it. There was a row of houses. It used to be used as a kindergarten, but now it has become an expert appraisal site! And a little further to the side is the People's Cinema in Linhai City!

Therefore, Jia Sidao and Ji Yanran's vehicles naturally parked in the square at the entrance of the theater.

However, before getting off the bus, the two felt the atmosphere unique.
Chapter completed!
