"I see you brought some instruments......" Yan Juan looked at his small suitcase.

"Not bad. Even when dealing with Mecca, I am used to taking my own scales. ”

"You say forty-five carats, don't you count the carats of each diamond in the industry?"

"For loose diamonds that have not yet been set, because the difference in particle size is not too big, it is customary to use the number of pieces per carat."

"Oh." Yan Juan nodded, "Forty-five pieces per carat, is it relatively large?" ”

"For a small diamond, the weight is enough. No matter how large it is, it is expressed in carats per diamond, and the smaller ones even exceed 90 carats. ”

"Then this bag of diamonds, one is equal to more than 0.02 carats, and it is enough to make earrings or bracelets."

"Yes. Moreover, this batch of colorless diamonds from Mecca is of high quality. Yan Yixin patted the bag with a smile, "That's why I'm willing to add ten percent to buy that pink diamond." First, because someone preemptively struck Mecca, and Mecca had to get it back, the cost would of course be a considerable number. Another reason is that the quality of his diamonds exceeds the original agreement.

"Oh, reciprocate!" Yan Juan was still puzzled, "But, with ten percent of your bonus, you should pay more, right?" ”

"Recently, the price of pink diamonds has risen dramatically, and Mecca has to pay additional costs. What's more, our cooperation with Mecca is long-term, although in the short term, it seems a bit silly to lose our own interests, but in the long run, it is beneficial, and Mecca will allow us to get greater benefits in the Brazilian deal. ”

"So you're willing to pay 10 percent more, even though it's a lot of money." Yan Wan nodded.

"Yes."

"Shall we ...... Want to stay two more days? Yan Juan asked tentatively.

"Not bad. Don't worry, Mecca will arrange it for us. Yan Yixin smiled happily, which made Yan Juan think of the enthusiastic Rio de Janeiro beauties for the first time.

It seems that all men are good at this!

She didn't know why, and suddenly she was down.

When they returned to the hotel, it was late. The mountain road along the way made Yan Juan's skeleton almost scattered. So Yan Yixin didn't talk nonsense, so he said goodnight to her.

Yan Juan didn't have time to figure out if he was in a hurry to meet the passionate beauties of Brazil, so he fell asleep and pulled Zhou Gong's sleeve to play chess.

It wasn't until the next day that she realized that the so-called "arrangement" was completely different from what she had imagined.

There are no passionate Brazilian beauties, but another group of diamond dealers.

"You know our rules, I'm just in charge of pulling the strings for you. As for the color and quality, it's up to you. When Mecca had said this, she walked away without even looking back.

"What does this mean......" Yan Juan felt confused.

"This means that these businessmen may be shoddy, or even use synthetic diamonds to make up their numbers." Yan Yixin replied in a whisper.

"That ......" Yan Juan looked at his face anxiously, and only relieved when he saw the latter's calm smile.

It seems that Yan Yixin is confident about this, so she doesn't have to worry about the sky falling.

Yan Yixin seemed to have a good conversation with a few diamond dealers, but Yan Juan noticed the impatience that flashed in his eyes. It seems that he didn't get the goods he wanted.

"I want pink diamonds, but not nail polish quartz." Yan Yixin said with a smile, his fingers flicking his knees.

The diamond merchants smiled and immediately took it back: "Mr. Yan, you are a person who knows the goods. We'll meet again tomorrow, and if you can afford it, you'll have the best diamonds. ”

It seems that Yan Yixin didn't even use the inch mirror to see that the diamond's shoddy eyesight made the young businessmen who originally deceived him finally pay attention.

Yan Yixin showed a look of concern: "Okay, if you have the best diamonds, don't worry that I can't afford the price." But pre-diamonds are not synthetic, spliced, and have not been laser and irradiated. I want a pure natural diamond with a certain level of clarity and clarity. ”

"Okay." Several businessmen glanced at each other and nodded solemnly, "Mr. Yan sincerely wants it, and he will definitely not suffer." ”

Yan Yixin sent off a few businessmen and returned to the room to pace back and forth. The center of his eyebrows was locked a little deep, and on his smooth forehead, a shallow word "Chuan" gathered.

"What's wrong?"

"Listening to the tone, maybe you do have the best in your hand. I think maybe we have to move positions to the head office so that we can have enough diamonds on the market before next year's London fair. ”

"Next year?"

"Yes, the London Exchange has a large number of sellers and buyers, and the volume of transactions is absolutely amazing. However, it would be better if you could find a sufficient supply before then. We don't have to spend more than budgeted money to grab the goods. ”

"Is there a lot of mixed cargo here?" Yan Wan asked.

"Well, it's inevitable." Yan Yixin nodded.

"Well, who keeps the price of diamonds high? It is no wonder that unscrupulous traders want to use shoddy products to seek greater benefits. ”

"In particular, diamonds with good clarity, high color grade and large weight are not easy to find, so some businessmen try to improve lower quality diamonds. This is permissible if the customer is informed in advance about the circumstances of the processing. After all, there are some customers who want to buy some diamonds that don't look like ivory for less money. The problem is that today's sellers are taking advantage of these improved diamonds and selling them for a much higher price. ”

"Shoddy...... I still don't really understand! Yan Juan was puzzled.

Yan Yixin showed a lot of patience for her diligence and inquisitiveness: "Generally speaking, several methods can be used, such as stitching, glass filling, laser drilling, radiation and heat treatment, and coating coating, but coating and coating are relatively old methods, and they are easy to find when identifying, so they are rare now." If you put it together, you can generally see the seam of the seam, and if you look at it in the light from the direction of the crown or pavilion, you can see the bubbles, and it is easier for experienced businessmen to identify. ”

Yan Juan listened with relish, and continued to ask: "Then if it is filled with glass, it should also be easy to identify, right?" After all, glass and diamonds are two very different substances. ”

"Yes, if you look at the diamond under a microscope, as the background brightens, the filling area changes from orange to blue, or purple-red to yellow-green, and you can see flowing structures and flattened bubbles. As for lasers, they are meant to eliminate inclusions inside the diamond. Radiation, on the other hand, is to change the color, and the difference can generally be seen in the immersion. ”
