The Treasure Hunt of an Antique Dealer

Just as Zhang Nan was still pulling his throat and shouting, the walkie-talkie hung on Alyosha also rang: Lao Tangna also found diopside.

Good sign, this is the rhythm of making a fortune!

Zhang Nan and others did not know: Xie Jianliang on the other side also heard the voice of the walkie-talkie, but Comrade Xie was not jealous at all! Just a few minutes ago, he had found green crystals interspersed in a large exposed granite.

However, he and Karimi, his temporary partner, were calm. This would be using a large crow's beak to dig a stone sample.

Very hard! Comrade Karimi took a lot of effort to smash down a large piece, about seven or eight catties.

Xie Jianliang picked up the stone and looked at it carefully, "Well, it's Kimberlite."

Karimi on one side took out the pen in his pocket and marked the location on the topographic map of the island.

"Let's go, let's go back, we can't let Lao Tang and the others be more beautiful."

Xie Jianliang's temper doesn't like publicity, he belongs to the old scalper type who is honest and willing to do it: you are ranting, we don't have much here, we rely on practical actions.

Put the stone into the canvas bag, Karimi on one side carried a large duckbill pick, and walked to the camp.

But Karimi had a question in his heart and had to ask: "Xie Gong, we have all come here for almost one kilometer, and the distance from Tang Gong is at least 1.5 kilometers. Is this mine so big?"

This is a primary mine, not a secondary mine after the river has washed it. The range is incredible!

Xie Gong, Xie Engineer, Huaxia people generally call educated engineers this, kind.

Xie Jianliang and Tang Jichao both have the title of engineer, who would be judged in the army, plus the Xiang Zhangsheng, these three are still quite respected by ordinary people in the 1980s.

Xie Jianliang walked, "A typical diamond mine is only a few hundred meters in diameter. The most famous Yimeng diamond mine in Dongshan has a diameter of more than 400 meters. This size is more common.

I have heard that there is a diamond mine in the Soviet Union that may exceed 1 km in diameter, but that kind of situation is very rare. The current situation shows that there is probably more than one kimberlite pipe here. "

The diameter of the "Peace" diamond mine in the Soviet Union is more than 1.2 kilometers. However, as an engineer in the military, Xie Jianliang can only "listen" to this matter: this peace mine is still highly classified by the Soviet Union, and foreigners can only pass through the West. Some public, satellite-photographed data in the world know the existence of that super large mine.

"Good thing?"

"Of course it’s a good thing! It’s not uncommon to have a single rock pipe. If there are two rock pipes, then there may be a whole batch of rock pipes nearby. Many kimberlites are piled together. The Kimberley mine in South Africa is more than ten. A group of rock pipes has been mined in batches for hundreds of years."

Pointing to the canvas bag on his back: "The associated ore on this ore is olivine, and what Xiang Gongna found is green diopside, which is likely to be two rock pipes.

However, it may also be one. These two types of associated mines sometimes appear together, which will become clear after drilling.

But the boss definitely made a profit this time. The Kimberlite is a kind of alkaline, porphyritic, breccia-like mica peridotite. Among them, the porphyritic kimberlite, which has a porphyritic structure and is rich in coarse grained olivine, contains more diamonds. , While the kimberlite, which has a microscopic porphyritic structure and is rich in phlogopite, is poor in diamonds.

The ore here is of standard porphyritic structure, rich in coarse olivine particles, and there is absolutely diamond in it. I don't know how much gem-grade fineness will be. "

Karimi is also good, this will be a guest miner, and then asked: "Thank you, how do you detect it?"

"We brought the crusher and the specific gravity fluid. As long as we carried a tens of kilograms, we would know the result soon after the crushing, and it would not take two days."

Here Xie Jianliang and Karimi walked towards the camp while chatting, and Tang Jichao on the other side was also approaching the camp.

The joy of discovering high-value mines for geological people is beyond words!

On Zhang Nan's side, Chen Hao and the two pilots who were watching the show ran over with explosives.

"Boss, how do you do it?"

Zhang Nan pointed to the rocky surface of the ground and said, "Blow me a few hundred kilograms."

The Xiangzhang next to him heard it, and quickly said, "Don't worry! Boss, a dozen or twenty kilograms of a sample is enough. If there are more, it doesn't make much sense. Just find a few more."

The kimberlite on the ground has been eroded by the natural environment, and there are some cracks, which can actually be knocked down with a screw, but it is obviously easier to use explosives.

Before I came here, I didn’t have any problem with using a 1,000 kg big guy, but I actually brought 50 kg of ammonium nitrate explosives: at the engineer’s request, only a few ounces of explosives would be enough.

After discussing with Alyosha, Chen Hao and Alyosha didn't even need a pneumatic pick, so they planned to use their head to dig a hole through the crack in the rock on the ground.

The big guy started to work. At this time, both Xie Jianliang and Tang Jichao took back the ore specimens: Tang Jichao’s hand was also a small diopside, and Zhang Nan was more concerned about the seven or eight jin of Kimberlite in Xie Jianliang’s hand. interested.

Looking through a magnifying glass, "Hey, thank you, there are no diamonds on it."

I watched some documentaries before rebirth: Someone mailed kimberlites online, and then people who searched for diamonds and sold stones in their own homes could make a lot of money. This is probably an alternative gambling stone.

Really, someone found a diamond after smashing the stone, but it was generally very small.

Xie Jianliang smiled and said, "Boss, if there is a gem-quality rough diamond that adds up to two or three carats in a ton of kimberlite, this is an absolute bonanza."

Means: Boss, this is a diamond mine, not the Chinese cabbage in the ground!

"Should we smash it and take a look?"

Xie Jianliang nodded.

But I haven't used a big hammer and chisel on the other side. I heard Xiang Zhangsheng and Chen Hao talking about blasting.

Have to listen!

Why?

The camp is just a few tens of meters away, and this one is afraid of rubble splashing.

However, Xiang Zhangsheng obviously hadn't figured out Chen Hao's profession before.

"Don't worry, Xiang Gong, I will blast the rock loose, and promise not to hit us on the head."

Qiu Bo assured him that Zhang Nan said loudly: "Zhang Sheng, just get out of the way, Qiu Bo is an expert."

All right, everyone returned to the camp with the stone in their arms and informed Guan Xingquan and Paul, who were still checking the environment to the west, that there would be a small blast. Don't be surprised then.

A group of people hid behind the tent with two layers of thick canvas, which should be safe enough.

Before smashing the ore with a hammer, Qiu Bo and Alyosha returned with a wire.

Electric detonation, insurance.

Connected the detonator, gestured to the left and right, opened the insurance, and Chen Hao pressed the detonation button.

With a "boom", it was dull, not particularly loud, and there was no sharp whistling sound after the gravel was blown up.

A few seconds later, a group of people swarmed to the blasting point.

Xiang Zhangsheng was the first to say to Chen Hao: "First-class technology!"

The rock within one meter in diameter was blasted, and the cracks scattered like a spider web. With one-handed small duckbill pickaxe, the ore can be pried up one by one.

Zhang Nan knocked on one piece, and there were many cracks on it. There were no diamonds on the surface, so I chiseled it into three pieces with a duckbill pick: one of them was embedded with a shiny object similar to soybeans on the surface.

"Diamond!"

Nicole was the first to call out. Several engineers here came over to take a look, and immediately said: "It's a diamond, it should look like two carats!"

Zhang Nan held the ore in his hand. The small diamond in front of him was not round, but two-thirds of it was exposed from the ore. It had a translucent appearance, a bit like a diamond-shaped cube.

It's like a little rock candy.

With a ten times magnifying glass, you can see that the inside is very transparent, anyway, except for the stripes on the surface, as long as the inside is a few tenths of a millimeter, it is the flawless texture of a diamond!

Everyone passed it around, and finally returned to Zhang Nan's hands and asked Xiang Zhangsheng: "Look, what level can this one reach?"

After receiving the ore and using a magnifying glass, it seemed that it took about half a minute. Xiang Zhangsheng said: "At least the clarity of vvs1 and the color is excellent and white. We call it No. 98. In the West, it should be called F grade. Three grades, very good high-end gem-quality rough diamonds."

The third grade of diamond color grade, which is already very good!

Grade d is the highest color grade among the colors of diamonds completely colorless ~www.wuxiaspot.com~, extremely rare! E-grade is colorless, and only a small amount of color can be detected by gem identification experts. It is also a very rare diamond.

Note that it is rare, not uncommon!

This rough diamond is F grade, a small amount of color can only be detected by jewelry experts, but it is still considered a colorless grade, which is definitely a high-quality diamond.

The g from the f grade down to the h grade is considered to be close to colorless. It will only be found to have a slight color when compared with diamonds of higher color grades. However, if there is no comparison, most people will not feel that diamonds of this color grade still have a very good color. High value.

The i and j levels below are still considered "close to colorless", and slight colors can be detected, but the value is still high.

As for the k to m level, the color is darker and the fire color is poor, and the value is not very high.

Generally speaking, diamonds of grades d, e, f, g, h, i, and j are good before j. Without careful comparison, most people will not think that they have a color, especially a single piece of inlaid jewelry.

Although the value of k, l, and m diamonds is relatively low, some jewelers deliberately use colored k gold to inlay this type of yellowing diamonds, and as a result, "low-grade goods" still sell at high prices.

Regarding the level of color, many people have this question: "If the color continues to yellow, it will not become a yellow diamond, but the value will be higher?"

Will not!

The yellowish color of colorless diamonds should be understood as "dark yellow/brownish", which is not the same concept as the bright and bright yellow of yellow diamonds. Wouldn't it mean that the yellower the diamond, the better?

Three experts agreed: "Very good diamond!"

Well, this diamond is very good, that

Everyone suddenly reacted, there are still a lot of broken stones!

Dig it!
