Chapter 462: 461. Appreciation Party

Xiao Chong used the ability to reverse time, and about these rubies and ruby ​​artworks, scenes of old times appeared.

The first image shows a boiler-like instrument with a fat black man working on it, and behind the black man's butt is a test bench with a bunch of beautiful 'rubies' spread out on it.

The second image is still in this environment. There are more rubies, and there are many black people. They are observing the rubies with a magnifying glass. Some of them are left on the table, and some are thrown into the trash can at the foot of the table.

Seeing this, Li Du was sure that these rubies were fakes, the most disgusting synthetic rubies in the jewelry market.

Synthetic ruby ​​technology has been born for half a century, and the cost of this thing is very low, which cannot be compared with the price of natural ruby.

How cheap is this stuff? Most of the cost is the cost of cutting and grinding rather than raw materials and production costs. In this way, some unscrupulous jewelers sell synthetic rubies as natural rubies to make huge profits.

The reason why synthetic ruby ​​is so notorious is that its advent almost destroyed the ruby ​​market.

It has a variety of synthesis methods, such as the common hot melt method, flux method, hydrothermal method, Venuyi method and so on. Some counterfeiting methods are very sophisticated, and the synthetic rubies are almost exactly the same as natural rubies in terms of physical and chemical properties, so it is impossible to judge whether they are true or false.

It was in this situation that people lost interest in natural rubies because they were too gullible.

Li Du didn't know whether the three were deceived or brought these fakes to act for him. After discovering that the rubies were fakes, he became more suspicious of the identities of the three.

After thinking for a while, he tentatively asked: "These rubies are really beautiful, but are they genuine? I heard that some synthetic rubies are the same as real ones, and it's hard to tell the real from the fake."

Du Dayuan smiled calmly and said, "How can it be difficult to tell the real from the fake? Xiao Li, you have been deceived by the news on the Internet. The real one can't be fake, and the fake one can't be real. For experts, whether a gemstone is natural or synthetic can be determined at a glance. figure it out!"

"Is this all true?" Li Du asked.

Du Dayuan said firmly: "Of course, how could Christie's accept fake rubies? This is a real ruby ​​that has been appraised by many gem appraisers in our auction house."

Ma Cheng added: "These are the main characters in this autumn auction in Phoenix, and many people come here for these jewels."

As he said that, he took out the materials of Christie's autumn auction, which really had an introduction of ruby ​​jewelry.

Seeing these materials, Li Du's suspicion began to waver again.

Du Dayuan picked up the ruby, took out his work ID card, looked at it, and said, "Fortunately, no coffee was spilled on my ID card."

Li Du's heart moved, yes, he can still check these work permits.

The little flying insect re-used the ability to reverse time, and the target was Du Dayuan's work permit.

The first scene that appeared was in a closed room in a basement environment. Du Dayuan, Ma Cheng and others were busy in front of some instruments, some were in charge of photos, some were in charge of computer design, and some were printing.

In the next scene, Li Du saw a person who shouldn't be there: Ma Zhi'an.

Ma Zhian operated an electric heating machine and put a layer of tempered film on the certificate.

Seeing this, Li Du couldn't help scolding his mother: These people are liars! Not only them, even Ma Zhian is a liar!

Ruby can be explained that they were deceived, but how to explain the production of false certificates? Could it be that the employee ID cards of Christie's were made by a few Chinese in this dark room?

But this deception was too meticulous, even after seeing the truth, he still couldn't believe it.

There is no doubt that Ma Zhi'an and others have spent a lot of effort to deceive themselves, but what are they trying to do? I am a treasure hunter myself, and I have indeed harvested a lot of valuable things, but they haven't made them public, so they shouldn't know.

Li Du was full of doubts, Ma Cheng urged: "Little Li, don't you still have some good things to appraise? Hurry up and take them out, we will show you."

Hearing Ma Cheng's urging, he couldn't help but sneered and was about to call Luo Qun in to deal with these guys.

But then he realized that the police had no reason to arrest the three of them. They hadn't cheated, but instead helped him identify several fake famille rose porcelain.

In this way, even if they are arrested, they can say that this is a joke among the Chinese, and the police have nothing to do.

He was hesitating here when Hans' phone rang.

Seeing this, he resorted to a tactic of delaying the attack, saying: "Wait a moment, Boss Fu, who called you?"

"It's that guy Ollie," Hans picked up the phone and chatted.

After a while, he hung up the phone and said, "Ollie and the others want to have a party, thank you for leading them to get those good things in the Hopi reservation."

"In addition, they also told us a piece of news. Those California guys in Ball know that we have been to the Hopi reservation, and they are going to take a look."

Li Du nodded, and then his brain flashed, and he thought of another plan. If it succeeds, he can kill two birds with one stone!

After hearing what Hans said, Ma Cheng showed a surprised expression: "Have you ever been to the Hopi reservation? And got some Indian artwork? They have a lot of valuable things there."

Li Du smiled and said: "Yes, but they are all placed in the camp. If we want to identify these things, we have to go to our camp."

Du Dayuan asked hesitantly: "Do you still have a camp? Where is it? It may not be convenient for us."

Li Du said: "It's in Flagstaff City, very close from here. Don't worry, our camp is absolutely safe. In addition, you can not only help us with the identification, but also my colleagues. They also have a lot of good things. goods."

Ma Cheng licked his lips, and the three of them quickly exchanged glances, and then he said, "Okay, let's go and have a look, Mr. Du, just take care of the jewelry when the time comes, just be careful."

Li Du said: "This is great, the three teachers can rest assured that the safety of our camp is absolutely fine. Besides, how about this, I will have a party tonight, Jianbao party, how about it?"

The three readily agreed, with expectant expressions on their expressions.

Li Du said to Hans: "Inform everyone to hold a party, bring your valuable things to the teachers to appreciate, and inform Boer and York."

"Why notify the California guy?" Hans said dissatisfied.

Li Du said: "Don't they have a silverware worth hundreds of thousands? Let the three teachers help them appreciate it, give them some help, and ease our relationship."

Hearing what he said, Ma Cheng laughed and said, "Hey, Xiao Li, do you think we are free laborers? You have caught strong laborers, haha."

There was a bit of dissatisfaction in the words, but the tone was very cheerful. Obviously, he was willing to do this.

Li Du was also very willing.
