Li Yi stared closely at the big diamond underground, looking for all the flaws visible to the naked eye as much as possible, and before he knew it, his body was almost lying on the ground. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Huh? What are you doing? ”

As soon as Zhou Hang turned around, he saw Li Yi's strange behavior, and couldn't help but come over and stare at the ground in front of him, what is this guy looking at?

"Oh, nothing."

Li Yi pulled twice on the ground with his hand, picked up a blue garnet the size of a mung bean from the soil, got up and handed it to Zhou Hang,

"I saw a gadget."

"I rub, you can see this? No wonder you kid is so good at gambling stones, what kind of eyes do you have! ”

"Hehe, luck, luck!"

Li Yi laughed embarrassedly twice, fortunately there is such a garnet on his face, otherwise this matter is really not easy to explain.

"Mr. Han, that's not how we choose the beneficiation, right? Pulling them out of the soil one by one? ”

"Hehe, how can you! Depending on the ore, there are generally three methods of beneficiation. The basic principle of bouncing beneficiation, heavy medium beneficiation, and panning pan beneficiation is to use the specific gravity of diamonds to artificially separate the ore containing diamonds from ordinary stones......"

"I feel troublesome when I hear it, but it's a pity, if all of our workers can be like Mr. Li, it will be troublesome, one person will send a big pot of soil, and let them pull it slowly."

Zhou Hang played with the garnet for a while, then handed it to Han Fu again.

"The quality of this grain is not bad, but unfortunately it is too small, it should be worthless, right?"

Han Fu nodded, just wanted to comment, and suddenly saw Zhou Hang squatting down, his five fingers bent into a rake, and gently scratching and pulling on the ground, he couldn't help but be a little surprised, could it be that Mr. Zhou also found something?

"No, I just want to try it, can I find something out of this way......"

With these few words, Li Yi has gone through the big diamond carefully, and he can basically determine that this diamond is at least slightly flawed above level 2. In other words, if a large diamond of more than 100 carats can be cut, its value will be at least more than 3000000000000000000000000000000000000000000000000000000000

However, it is a little regrettable that the yellow color of this diamond can only reach Fancy Intense Yellow at most, and if the color is a little darker, it can reach the best color of the yellow diamond, Fancy Vivid Yellow, its value may skyrocket by more than 50%!

"30 billion, plus other diamonds, even if the real reserves are only 1.5 billion, this is a good deal. And, most importantly, a yellow diamond like this is not something you can buy if you want to......"

Li Yi glanced at Zhou Hang, who was squatting on the ground and pulling around, smiled slightly, and pretended to kick a potato-sized stone to the side with a casual kick.

"Let's go, Mr. Han, let's go to the beneficiation side and have a look."

Han Fu nodded, turned around and was about to leave, when suddenly, Zhou Hang, who had been paddling on the ground, let out a burst of laughter,

"Hahahaha, so I can too! This mine is good, it's a bonanza! ”

What do you mean? Could it be that this guy also found a gem?

As soon as Han Fu lowered his head, he saw Zhou Hang leap and jump to the place where Li Yi kicked the flying stone just now, and with a quick stroke of his five fingers, he picked up a fist-sized stone from the ground.

"Hey, look, is this a yellow diamond?"

Han Fu took the stone and looked at it, hey, don't say it, there is really a pale yellow diamond about two carats in size on it!

Nima, look at the luck of others, no wonder they dare to take this 20% stake! But......

"Mr. Zhou, your piece should not be a yellow diamond, this should be a yellowed white diamond."

"Yellowing white diamonds? What do you mean? ”

Li Yi took the ore and looked at it, and said with a smile:

"According to the Gemological Institute of America's color grading system, white diamonds can be divided into 23 grades, which are represented by the letters D-Z. Generally speaking, from grade I, white diamonds have a little yellow, which is a yellowish white diamond, and its price is generally about one-fifth lower than that of white diamonds of the same weight and quality. Yellow diamonds, on the other hand, are yellow diamonds that exceed the Z grade, and this kind of diamond, depending on the color, can cost a quarter to a half more than the same grade of white diamonds. ”

Han Fu gave Li Yi a thumbs up, and then said:

"Yellow diamonds of the color diamond grade, according to the different shades of color, are generally divided into light fancy yellow, fancy yellow, fancy intense yellow, fancy dark yellow, fancy vivid yellow. Although yellow diamonds are more common, several yellows above Fancy Intense are rare, especially Fancy Vivid yellow, which accounts for less than 5% of yellow diamonds, and this type of yellow diamond is particularly valuable. ”

He handed his hand to Zhou Hang as he spoke,

"Mr. Zhou, the grain I am carrying in my hand is a brilliant yellow, you can compare it."

Zhou Hang glanced at the diamond ring on Han Fu's hand, and then at the piece of ore he found out, and found that the difference between the two seemed to be quite big, so he said:

"I don't understand what you say so much, let's keep it simple, just tell me what level this diamond is!"

Han Fu smiled bitterly and opened his mouth, embarrassed to speak, but Li Yi said unceremonently:

"Generally speaking, white diamonds below K are not collectible, but unfortunately, this one of yours is below K grade!"

"I'll rub it, dare to say it, you just want to say that I found out that this diamond is not worth much, right? Phew! This is your jealousy, the jealousy of the red fruit! ”

Han Fu shook his head and sighed,

"That's the problem! Diamonds below K can no longer be regarded as gemstones, and can only be used as industrial diamonds, but our mine produces the most diamonds! Otherwise, with the remaining reserves of this mine, how can the valuation be so small? ”

Li Yi nodded, and suddenly remembered a question, could it be that the difference between the two valuations is due to the change in the proportion of gem-quality diamonds? But it shouldn't be, if the proportion of gem-quality diamonds really increases significantly, it makes no sense that Wang Shaofeng doesn't know?

"Mr. Han, I remember that there was an appraisal in the mine two years ago, but why is there such a big difference in the value of this appraisal this time?"

"This ...... I don't know too much about the specifics, Mr. Song is responsible for the assessment, or wait for him to come, you ask him? ”

Seeing that Han Fu's face seemed a little embarrassed, Li Yi gave Zhou Hang a look, it seems that there should be a story here! But his sister, didn't you say that you found the appraisal company this time? Moreover, it has a good reputation!

Zhou Hang shrugged his shoulders and spread his hands, the company is right that I found it, but if they really did something, how could I know? Anyway, this share was not bought, so it doesn't matter if you don't lose money, why do you kid care so much?

Why do I care so much?

Li Yi glared at Zhou Hang fiercely, if you kid knew that there was a big yellow diamond of more than 100 carats buried under the ground, I was afraid that you would manage more than me!

Han Fu pretended not to see the eyebrows of the two people, and said with a smile:

"Didn't Mr. Li just say that he wanted to go to the beneficiation place? Or do we go over now? ”

"Okay, let's go over there and have a look, see if I can get a yellow color like you, and I'll also get a ring to show off."

"Hehe, although bright yellow diamonds are rare, but if Mr. Zhou wants it, it is still very simple, now there are a few in the safe on the mine, the two bosses can pick one each, I will calculate the cost price for you!"

"Haha, I like Lao Han's attitude, just do it, and shareholders can't take it for nothing!"

Han Fu smiled bitterly, why did this sound so wrong? If you really want to be an irrelevant person, it doesn't matter if you give you two grains, but you are shareholders, if I dare to give away the diamonds mined in the mine, I am afraid that the problem will be more serious than selling them to you at cost price, right?

The three of them discussed the quality of diamonds all the way to the concentrator. Strictly speaking, there is no difference between diamond beneficiation and ruby beneficiation, but the production process here is more advanced than that of Mogu, and most places use machinery instead of labor, so that not only is it more efficient, but also the possibility of omission is smaller.

"It's really no different from the gold rush on TV......"

Zhou Hang watched a large electric sieve dangle in the water, and after a while, he scooped out a pile of gravel and put it on the belt to vibrate repeatedly, and couldn't help but walk over with interest, grabbed a handful of gravel and looked at it, suddenly his eyes lit up, and he picked out a grain from it,

"Haha, now you can't say I'm worthless, right?"

Li Yi leaned over and took a look, hey, I didn't expect it to be a brilliant yellow, although the particles are not big, but after all, the color is superb!

His gaze swept over the belt, and he saw several real yellow diamonds, and he couldn't help frowning, diamonds of this quality can appear frequently, but why did Han Fu say just now that the quality of this mine is not good?

"Mr. Han, I think the quality of this mine seems to be pretty good......"

"Oh? Seems to be a good ......."

Han Fu grabbed a handful of gravel and glanced at it, and was a little surprised, but what surprised him was not the number of yellow diamonds screened out of this batch, but the luck of these two people. Because although this situation like today is not common, it is not uncommon, but these two only came here once in a while, so they met them, could it be that these two guys are really related to this mine?

After walking around the concentrator for a while, Zhou Hang suddenly noticed that there were many people bending over and picking on a large sand pile on the side, and couldn't help but ask curiously:

"Mr. Han, what is the place over there?"

"Oh, it's all the waste ore that has been screened out over there, and those are the families of the workers in the factory, and the waste ore pile is also a kind of welfare."

"And this kind of thing? If diamonds can be found in scrap ore heaps, why not more than twice? (To be continued.) )
