Chapter 220

[3. Diamond. 】

[Diamond, commonly known as "diamond", it is a mineral composed of carbon elements, and it is also the original body of common diamonds. 】

[Diamond is the hardest substance that exists naturally in nature. 】

[Diamond has a variety of colors, from colorless to black, and colorless is the best. 】

They can be transparent, translucent, or opaque. 】

[Many diamonds have a yellowish tinge, which is mainly due to the impurities contained in the diamonds. 】

[In addition, it has a very high refractive index and strong dispersion properties, which is why diamond reflects colorful flashes.] 】

【Uses:】

[1. Industrial use. 】

[Ground "103" quality drill bits and oil drill bits diamond, diamond for wire drawing die, diamond for abrasives, diamond for dresser, diamond for glass knife, diamond for hardness tester indenter, diamond for handicrafts. 】

[If it is applied to the audio paper cone, the sound quality of the speaker will be greatly improved.] 】

[2. Chronic poisons. 】

[During the Renaissance, a chronic poison made of diamond powder was popular among wealthy families. 】

[When people take diamond powder, diamond powder will stick to the stomach wall, in the long-term friction, it will make people get gastric ulcers, and if not treated in time, they will die of gastric bleeding, which is a chronic poison that is difficult for people to guard against. 】

[3. Ornamental gemstones. 】

[Diamonds sparkle in light due to their high refractive index. 】

[Giant diamonds can be worth a fortune.] 】

[And diamonds with dark colors are more expensive.] 】

[The most expensive colored diamond is an aqua blue diamond with a bluish tinge.] 】

【......】

【Main Origin:】

[The Bernat brothers, who discovered the Kimberlite diamond mine in 1870.] 】

[It was this discovery that made it known what kind of rock might contain diamonds. 】

[It turned out to be a volcanic rock formed by the cooling of magma in ancient times. 】

[Later, the researchers found that in addition to diamond, this volcanic rock also contains two minerals called garnet and olivine.] 】

[Therefore, in those locations where garnet and olivine are produced, the possibility of finding diamond mines is relatively high.] As a result, garnet and olivine became the "indicator minerals" in the search for diamonds. 】

[The method of finding diamond ore according to the indicator minerals was not discovered suddenly on a certain day.] 】

[In the 70s of the last century, John Janey, a geochemist at the Smithsonian Institution in the United States, published his research results after carefully studying the relationship between garnet and diamond. 】

[However, before that, in the 50s of the last century, there were already geologists who had been looking for diamond mines all over the world according to the indicated minerals. 】

[Diamond mines have been found all over the world. 】

[Among them, Australia, Gangguo, Maoxiong Country, Botswa and South Africa are the five famous diamond producing areas. 】

【......】

"I'm not mistaken, right? South Africa still has diamond mines!"

"It's... Good things come in pairs! Gold and diamonds are dug together! Now you make a lot of money!"

"Wonderful, wonderful, gold, gemstones, if you can find a mine, you don't have to worry about it in this life. "

"First come, first served, our fleet is ready, go first. "

"Dog thief, you are a son of man in vain, what about going together?"

“......."

In ancient times, the people were even more anxious about going to sea.

Many people have gambled on their families and have already set off.

Han dynasty.........

Liu Bang rubbed his eyes.

Make sure you're right.

Then, his eyes widened. (If you read a violent novel, go to Feilu Novel Network!)

No!

How can a gemstone be used as a poison?

It's still a chronic poison, and it's hard to prevent.

If this is for the gangsters to find...

Wouldn't it be possible to poison him silently!!

Liu Bang almost burst out with foul language, and roared anxiously: "Immediately find this gem for me to go to sea, and I must not let others dig it first!"

Tang dynasty.

Li Shimin was amazed.

"The hardest thing in nature is a gemstone. "

"Can you make weapons and arrows?"

He couldn't help but think about it.

If you make diamonds into weapons, you won't be killed on the battlefield, and you won't be afraid of the weapon cutting to the blade.

And making it into an arrow is even more terrifying, there is nothing to defend against!

As for whether it can be forged, I'll talk about it when I find it. []

Li 4.5 Shimin waved his hand and ordered: "Immediately throughout the country, look for garnet and peridot." "

"If you find these two stones, report them immediately. "

Both stones have the potential to lead humans to diamonds.

Li Shimin naturally did not forget this.
