The water head refers to the transparency of the jadeite.

If this piece of window material is made into small pieces and carefully polished, his water head can be at least six points of water.

The head of the six-point water is a super high commodity in the jadeite carving, and the price is also sky-high.

Jadeite is among the geologists of the headquarters, which is a subject that has been studied and pondered since the last century. Almost every institute has hundreds or thousands of jadeite specimens in its laboratories and showrooms.

At the end of the last century, jadeite was popular all over China, among which gambling stones were the most.

In a certain year, several bigwigs from the headquarters traveled to Yunnan, and when they arrived at TC, the ancient capital of the thousand-year-old jadeite, it coincided with the local jade festival.

A few bigwigs relied on the fact that they were high-achieving geology students, and there were top experts from the Caiyunnan Institute of Geology around them, and they played gambling stones.

As a result, a few bigwigs borrowed money to buy tickets back to Yandu.

The two top experts from the Caiyunnan Institute of Geology were the worst, and they even lost their pants.

suffered such a great humiliation that several bigwigs killed TC again the following year.

This time, the bigwigs not only prepared sufficient tickets, but also the most powerful masters of the various museums and institutes in the headquarters jointly escorted them.

In order to be ashamed, the bigwigs also directly airlifted an imported X-ray machine.

The result of this southward trip was just like when Ah Gui fought the Jade Country, defeating and losing, and returning home.

Since then, the bigwigs at the headquarters have been consumed with Jade.

Up and down, each museum and institute of the headquarters has opened a jade research room, specializing in jadeite.

Ten years of hard work, to this day, the headquarters has not only made remarkable achievements in the research of jadeite, but also personally rolled up its sleeves.

Every year in the Emerald Kingdom, the headquarters will participate in the war.

In China, the headquarters has also opened its own public market belonging to Shenzhou jade jewelers in Guangdong Province!

It's just that at the beginning, a few bigwigs swore to build a machine that could shine through the jade rough, but the stone sank into the sea.

In the mineral identification area, the Nanshu of the headquarters is well-deserved No. 1.

In the nineties, Fangzhou, who was in full swing, helped build the jade country and got back a large number of jadeite roughs.

Pu Ziheng, the leader of the Southern Army, was recognized as the first person to gamble in Fangzhou at that time.

Your brother once said that Nanshu originally stored nearly 100 tons of jadeite rough stones, and after the disintegration of Fangzhou, Pu Ziheng took the best batch of rough stones to the headquarters first.

When it was counted afterwards, half of the jadeite rough in the inventory of Nanshu was missing.

Among them, there are several oversized rough stones, which are of extremely high grade, and their value far exceeds the sum of Zhu Di Lanbao and Jinji No. 1!

So far, no one knows where these oversized rough stones are.

After a brief wail, the whole playground began to get busy.

To my left, Huang Shengyang was busy testing the maroon piece of wood.

On his desk, there are measuring cups, water, and a hacksaw.

The window material, which was also a blue water jadeite, had been thrown aside by Huang Shengyang, and it seemed that he had already recognized this specimen.

Although Huang Shengyang is violent and unruly on weekdays, he has a completely different attitude in his own work.

His skills are equally remarkable.

Leaned over and picked up the measuring cup from the table, first poured a little water on the blue water jadeite to observe the leather shell, and then turned on the light to see the crystal structure and color changes inside the jadeite.

I found that this piece of blue water jadeite is very interesting.

Its blue color is not pure, and there are a few yellow crystal impurities in the broken crystals. And the whole is grayish.

Although it is well planted, the blue hue does not look natural under the lamp.

But what is very strange is that there is no problem with the hardness of this window material.

If it is a new material, the Mohs hardness is not up to the old one, and it is between 6.6 and 6.8 at most.

On the contrary, the rigidity of this piece of material is excellent!

That's pretty interesting.

There are still people in the world like the Emerald Country

Where gem-quality jadeite is produced?

Footbasin ghost, Hassa, Takakasa, cactus country......

The jadeite of these countries is all marble.

Beautiful country?

The Great Mautegir River?

Their quality is not so high.

If more than one of the above countries is excluded, then the last one remains.

It's just that the jade in this place has never appeared in Shenzhou at all.

"Report!"

「444。 Speech."

"Report to the invigilator, I need a polarizer, a beamsplitter, a magnifying glass, a refractometer, an X-ray fluorescence spectrometer, an infrared spectrometer, a laser Raman spectrometer, ......

When these words came out, the invigilator froze in place, and the others looked up one after another, all showing incredible eyes.

Needless to say, in the eyes of the proctor and so many contestants, I was crazy again.

"What did you say? 444。 You do it again."

Again, I'm asking for these instruments too.

It was only during the second opening that I added a microscope, an electron probe, and a cathodoluminescence spectrometer.

"444, are you not brainy enough or are you short-circuited by nerves?"

"Do you think I'll give you these things?"

After the first two rounds of assessment, I don't think any invigilator is a good thing.

The disciplinary supervisor is slightly better, but it can only barely be counted!

For such people, they have to clean up when they have the opportunity!

"Report to the proctor, I think you have to give me these things."

"Over."

Hearing this, Huang Shengyang looked at me coldly, showing an expression of hopeless contempt.

The cabbage sitting behind me again shook his head, his mouth kept squirming, and he didn't know what he was reading.

"Ho ho ho ......"

Hearing my words, the invigilator was amused and rolled his eyes to the back of his head: "You think I have to give it to you?" You're all right, 444."

"Friendly reminder, 444. It doesn't matter if your mind is empty, but don't get into the water."

"Give me a good test. Don't disturb other people. Otherwise, I will send you out myself."

There was a burst of suppressed laughter from the scene, all of which were directed at me.

I sat down in my chair and said quietly, "Report to the invigilator. I didn't have any brains, I didn't get into the water, and I didn't disturb the discipline of the examination room."

"I just want the instruments I said."

Syllable!

The invigilator slammed his backhand on the table and shouted, "444. You don't play tricks on me. One last warning."

I tilted my head and whispered.
