After carefully observing the diamond rough stones in the tray, Li Yi quickly noticed a problem, that is, among the rough stones produced in recent days, the proportion of gem-grade diamonds seems to have suddenly increased by a certain level!

Moreover, this improvement is not an ordinary improvement. If the ratio of industrial-grade diamonds and gem-grade diamonds among the diamonds produced before were about 50% to 50%, the current ratio has become 20% to 80%!

"The proportion of high-quality products seems to have changed a lot. Is it an accident?"

He picked up a diamond and observed it carefully.

"It shouldn't be. Mr. Li, three days ago, a new rock formation was dug in the diamond mine, and the proportion suddenly increased from the original half to half to almost 2 to 8. Moreover, I don't know if you noticed that the overall quality of gem-grade diamonds after the proportion changes is also improved by two steps compared to the previous diamonds!"

"Oh? The quality has also improved?"

Li Yi had only noticed the change in the proportions of the two before, and also noticed that the number of diamonds with relatively good quality seemed to be higher, but he only attributed this change to the change in proportion, but he did not expect that the overall quality had been improved. Hearing this, he couldn't help but pick up the magnifying glass on the table and looked at it carefully one by one again.

He carefully observed the raw stones left on the original mine and found that the colors of the gem-level diamonds in them were mostly h and i, that is, white and slightly yellow and white. Only a very small number of them could reach the g level. However, the diamonds mined in the past three days have very few slightly yellow and white, most of them are white, and about 10% of them even reached the f level of the excellent white!

Moreover, color changes are only one aspect. The most important thing is that the clarity of diamonds has also changed a lot. The original clarity level is concentrated in the private level of small flaws. About 30% can reach a very small vs level, but most of them stay at vs level 2. But now, not only 80% of the levels have reached vs level, 20% of them have also reached vs level minus flaw level!

In addition, the number of large diamonds weighing more than one carat seems to be much higher.

It turned out to be an all-round increase in quantity, color, clarity and weight, and it has indeed been improved by more than one level!

"What's going on?"

He threw the magnifying glass aside, and slowly played with a newly mined rough stone weighing more than 5 carats, his heart full of surprise.

"It should be because of the new rock formation. Mr. Li, after I discovered this change, I started to check the information. Finally, I saw a similar case in a magazine more than ten years ago. It was a mine pit in the Argyle mining area in Australia. At that time, they also dug a new rock formation and then found that the proportion of pink diamonds had a great increase. However, like ours this time, there has been no precedent for the comprehensive increase, including the number."

Han Fu looked at Li Yi with admiration. He felt that Li Yi had foresaw this change for a long time. Otherwise, how could he explain that he had just walked around the mine and decided to spend a lot of money to buy this diamond mine at sunset?

But, this is a bit amazing, right? Even this can be foreseeable?

He suddenly remembered what Li Yi said when he accompanied Li Yi to sweep the target that day. He could smell the smell of diamonds! A great hope arose in his heart. Perhaps, a new diamond mine could really be found in those targets!

Han Fu was a little scared by Li Yi, and as for Guangming and Zheng Shusen, they had long been stunned. Although Han Fu had told them that the quality of newly mined diamonds had undergone gratifying changes, he did not say so in detail. So at this moment, they were holding a handful of diamonds, desperately verifying the changes that Li Yi had just mentioned.

"There is a precedent because a new rock formation was discovered? This explanation is a matter of barely speaking, but this is really amazing. Isn't this a flash in the pan, right?"

"This is not certain, but I think it shouldn't be the case. Because if that happens, the changes that have occurred in the past few days will be even more unexplainable."

"So, I accidentally bought a gold ingot? Hahahaha, this luck is simply invincible!"

Li Yi thought that this is indeed the case, because if there is no change in quality in minerals, it will be fine. Once there is a change, it will definitely not be measured in a few days of mining cycle. Because the movement of the earth's crust is not so boring, it is just moving such a little amount to make everyone happy.

In other words, once a situation like what they encounter occurs, it will often last for a long time. This long period of time will definitely be calculated over the years, and it will continue to last for most of the time!

"Mr. Li, this is more than just a gold ingot! If the proportion has changed, it can only be said that your acquisition can make a profit. But like now, the overall quality has reached two levels. The value of this mine is probably underestimated if it doubles!"

Li Yi smiled and nodded, doubled? Haha, wait until you see the yellow diamond dug out, let’s tell me the specific value of this mine!

"Mr. Han, today's diamond selection has been released. Will you send it to you now?"

Several people had their own thoughts and were enjoying the joy brought by changes in mineral quality in their own way. The door of the conference room was suddenly knocked and today's diamonds were selected.

"Come on, get it right now!"

Han Fu rushed to the door in a few steps, opened the door, and couldn't wait to say to his assistant.

"Okay, please wait."

Five minutes later, the diamonds selected today were escorted to the conference room by several security guards. Han Fu snatched the small cotton bag from his assistant, found an empty tray, and a crisp sound, and then several heads in the office came over.

"It should be true, the quality has undergone a fundamental change!"

Han Fu held a magnifying glass and hurriedly looked at more than a dozen raw stones, then straightened his waist to announce the discovery, while Zheng Shusen held a yellow diamond weighing at least 8 carats, with an obsessive look on his face.

"The flawless yellow diamond with the best yellow color. If the knife is good, maybe it can even cut a 200-hedron, which is valuable."

"Oh? Can there be 200 more hinged cuts? Let's take a look."

Li Yi reached out to grab the diamond and looked at it carefully.

One of the 4C standards for diamonds is cutting, which is for diamonds with bright cutting methods. Because when other factors are the same, the diamond value of bright cutting technology is considered to be the highest.

As a round diamond, the standard brilliant cutting (57-58 sides) is also a classical turning worker. It is a very classic and perfect cutting method. As for the difference between this one side, it is the sharpest point in the bottom tip of the diamond.

Generally speaking, diamonds less than 5 carats do not have a bottom tip, which is 57 sides. In order to protect the diamond from damage, the bottom tip of large diamonds will generally be smoothed, so there is one more side, that is, 58 sides.

However, with the development of cutting technology, more and more surfaces can be cut, and people usually think that the more cutting surfaces, the more shining it will shine. Therefore, cutting technologies such as 74hedron, 88hedron, and 112hedron appeared, and the most of them were 200hedron cutting.

For round diamonds of the same size and quality, the price of 200-hedron cutting is much more expensive than 57-hedron cutting, but this situation is not absolute. The specific situation must be determined based on the diamond situation.

The diamond in Li Yi's hand may indeed be cut into a 200-hedron. If this cutting can eventually achieve perfect cutting, then the value of this diamond may exceed 15 million!

"It seems that the proportion of yellow diamonds has also increased."

"Well, many of them were yellow white diamonds before, but now they have become real yellow diamonds. Mr. Li., I really admire your vision!"

Han Fu endured it for a long time, and finally said this. After saying it, he felt relieved, as if his body had become much lighter.

"Haha, I've said a long time ago that my luck is basically invincible in discovering jewelry and jade! By the way, how is the exploration progress these days?"

"Well, that's right. Their main equipment was just shipped to the afternoon of the previous day. They also looked at several targets before, but they were not very optimistic."

"Aren't that optimistic? It doesn't matter. Just simply go through the other targets. The targets in Valley No. 2 need to be carefully explored, but also increase the scope and depth of the exploration. I always feel that there should be goods there."

After Li Yi and he had been to the target deep in Valley 2 before, he also said something similar, but Han Fu didn't care at all. But now it's different. Without Li Yi's instructions, he would take the targets in Valley 2 as the focus, especially when he finally walked over, Li Yi wandered around for more than an hour!

"In principle, the sales situation is still shipped according to the original channels. Mr. Zheng, you have to grasp it. The diamonds that may be used by jewelry companies must be intercepted first. As for the settlement price, just follow the 10% discount on the market price. Our company always has to take advantage of it, right? Mr. Han has any opinions on this?"

"No, no!"

"Well, let's go here first today, and then observe the last week. Then you will form two reports on the issue of improving the quality of minerals and the purchase price of jewelry companies. I will send one to Mr. Zhou, Mr. Wang, and Mr. Wang. Oh, by the way, there is also the small shareholder who holds 0.5% of the shares. What's her name?"

"Ning Ji, I have seen a lady with a very elegant temperament several times before."
