Beauty, you're here to be funny, right?

Uncles and aunts all laughed and didn't take it seriously. Liu Siyi simply didn't hear it, there was no problem with these tests, so his confidence came up all of a sudden, and he waited for the follow-up test results.

"The fourth is the detection of similar chemical components. Pencils and diamonds have the same chemical composition, both are carbon, but the physical structure is different. Many people use pencils to check the authenticity of diamonds, which is a very practical method. It's also very simple, when grading the diamond, moisten the diamond with water. As she spoke, the aunt wiped the water droplets that were originally used for testing on the surface of the diamond with her hand, and continued: "If you gently scratch it with a pencil, there will be no marks on the surface of the real diamond, while imitations, such as glass, crystal and other materials, will leave marks on the surface." In general, the accuracy of using a pencil to identify the authenticity of a diamond is high. ”

Speaking of this, the aunt took out a pencil from the pen holder on the desk and compared it on the diamond, but did not really scratch it, but looked at Liu Siyi and said: "This diamond looks very beautiful, I really can't bear to destroy it." ”

Liu Siyi knew what it meant, that is, if this was a fake diamond imitation, there would be flaws in this scratch, but it would be better to leave it like this. However, after looking at the previous test, he is now full of confidence, besides, even if it is different from the diamonds in this world, at most it is just ridiculed by beautiful women, can't it be used when he takes it back? So he smiled and said: "Of course I have confidence in my things, Auntie, you are free, and you don't have to take any responsibility." ”

"Auntie, since others are not afraid of damage, you should hurry up and inspect it." The beauty urged for fear that the world would not be chaotic.

The aunt nodded, and after glancing at Liu Siyi again, she carved the facets of the diamond. Starting with the largest facet at the top of the marquise, you cut it down in a regular circle, so that you don't miss a single facet.

Monorefraction has been done before, indicating that the diamond is a whole, and now it is just a matter of making sure that it happens.

At the end of the scribing, Auntie's eyes were already very serious, and she picked up a magnifying glass and looked at it.

In fact, the pencil marks could be seen with the naked eye, but she still used a magnifying glass, but she didn't believe that this piece was really a real diamond.

"It's a real diamond." The aunt herself didn't believe this conclusion, and said with surprise in her tone: "There are three other methods, if these three methods still can't be detected, then we have to use various instruments."

The fifth method is to measure the refractive index of a diamond. When drawing a straight line with a pencil on a white piece of paper, with the diamond face down and the tip pointing up, looking down through the tip, the natural diamond will not see the straight line drawn, while the imitation will see a distorted line. This is because the refractive index of a diamond is so high that all the light that hits the facets of the diamond is reflected and almost nothing is visible when viewed vertically from the tip. ”

As she spoke, the aunt didn't use any auxiliary tools, and with a random stroke, she drew a straight line that looked straight.

"Well, I didn't see a straight line." Auntie's expression became a little serious, and her tone was also very cautious: "There are two other methods, one is to look at the luster and fire of the diamond, and the other is to look at its growth point, both of which must be seen by professionals." In my experience, none of this is a problem. Therefore, I came to the conclusion that this diamond is genuine.

But! After all, manual inspection cannot be 100% safe, let alone such a large diamond, if it is true, once it is released, then the sensation it caused can be imagined.

So, if you don't object, Xiao Yi, I hope you can take this diamond back to the laboratory with me and identify it with the help of advanced instruments, what do you think? ”

"No problem, though, I wonder how long the process will take? If the appraisal is true, will you buy it, and how much will it cost? If you're not going to buy, then I don't think you need to do that. Liu Siyi didn't expect that the other party would complete the appraisal so quickly, but he reacted quickly and said his requirements one after another.

"Xiao Yi, to be honest, I still don't believe this diamond is real. Of course, if it's true, I'll buy it no matter what it costs, so don't worry. "Auntie said it very tactfully, although she didn't say how it was fake, but the meaning was obvious.

"Do you know how much it would be worth if it were a real diamond?" Uncle Long continued the topic and said directly: "It will be the largest cut diamond known in this world so far.

If you only calculate the value of the diamond itself, the Star of Africa is only tens of millions of dollars, but it represents extraordinary significance, not only the largest diamond in the world, but also represents the majesty of the British royal family, so it can no longer be measured by money, it is a truly priceless treasure.

If this diamond is real, then it is the world's largest diamond discovered for the first time in our country, and this significance is also extraordinary.

Xiao Yi, I think you understand what I mean by this? ”

"Yes, Uncle Long, I only came to play with Long Hao today, he is not here to come to see you, is there anything else?" Liu Siyi said as a matter of course.

"Xiao Yi, our family Xiao Hao often mentions you, especially after playing with the professional team a few days ago, he mentioned you several times, I believe in the relationship between you. So, I'll give you a real price: $50 million, what do you think? Auntie said very sincerely.

Liu Siyi was stunned, he came this time, naturally he had some preparations, checked a lot of information on the Internet, and naturally knew the price of diamonds. Even the largest African star in the world, if you remove the meaning it represents, the real value is about tens of millions of dollars. Now that the other party has raised the price to $50 million, Liu Siyi really has nothing to say. You know, if you find such a big diamond in our country, the meaning of the representation is different, and the value will immediately increase a lot. However, if you want to do this, the process is really complicated, without a certain background and strength, as soon as this news leaks out, don't try to keep your things.

Liu Siyi has this ability, but will he do this kind of thing now?

50 million US dollars is a big number, but Liu Siyi, who has experienced a lot, and even experienced life and death, will not be frightened by this now, his face still remains smiling, and he said: "Auntie, this price is very real, I have nothing to say." The diamond will be placed with you, and when the authenticity is checked, you will give me a card. By the way, I want RmB, which works well in China. ”

"Haha, it's really the back waves of the Yangtze River pushing the front waves. Xiao Yi, you must know that people's hearts are sinister, you just put this diamond here, not afraid that my uncle will swallow it? Uncle Long said with a laugh.

"Uncle Long, don't be joking, it makes me panic, I don't know what to do now." Liu Siyi also made a joke, but after thinking about it, it was right, if you don't have the strength, you can't blame others for swallowing your things, so he decided to show some strength a little.
