Chapter 579 578. Interesting (2)

Li Du pulled Alicia up, wondering: "The Gem Pit? What is that?"

Just as Brende was about to speak, Alicia punched him and said angrily, "Are you trying to kill us? Why do you let go of the handle while driving here?"

After being punched, Brende didn't get angry. Like his cousin Stephen, he was a good-natured character.

Facing his angry wife, he sneered and said: "I was too excited just now, hurry up, let's go to the gemstone pit, if we go late, we won't get anything."

Sophie wondered: "The gemstone pit? What? Are there many gemstones?"

Li Du shook his head and said, "Yes and no, the gemstone pit of opal refers to the fact that there are many rough opals."

The essence of all natural mineral gemstones is silica. The reason for the formation of opal is that about hundreds of millions of years ago, a certain area formed ultra-high temperature due to volcanic eruptions or popular impacts, and melted stones purified silica.

Silica melts into solution, and then flows like magma into the crevices and hollows of inland strata to deposit.

Generally speaking, this kind of deposition occurs at a depth of about forty meters from the surface, and the thickness of the sediment will increase by about one centimeter every five million years. The silica slowly condenses together.

During the next one or two million years of this period, the sediments began to slowly solidify with climate change. Opal is the part of the silica that is not bonded to other sediments and takes a long time to harden.

Among them, when the silicon dioxide liquid slowly condenses, it may not be able to completely separate from the external stones, and may fuse with stones or dust.

In this case, the original stone opal is formed, which means that the opal and the stone are combined into one. After excavation, some stones are wrapped in opal, or a part of opal is embedded in the stone.

Of course, there are other reasons why opal can have such a beautiful shape and rich patterns. It is a very complicated physical process, which Li Du barely understood.

The Gem Pit was obtained when he learned about this information, and the knowledge of rough opal was also obtained at that time.

The conditions for forming rough opal and pure opal are different. Almost all silica solutions will contact external stones during the flow and condensation process.

However, only a part of them will form rough opal, and most of them will be pure opal, which also involves a complicated physical process.

It is in this physical reaction process that the difference between rough opal and pure opal appears. Pure opal often appears alone, while rough opal appears in large quantities.

Rough opals are less valuable than pure opals because they tend to be combined with some ugly stones.

Gems are worthless if they are ugly.

However, with the development of modern science and technology, the value of rough opal has been improved.

Some machines can polish the outer stone layer of the original stone opal to expose the inner opal, and some machines can carve the stone layer to process a valuable image.

These two methods can increase the value of rough opal tenfold, especially the latter one, because opal itself is very precious, and people are reluctant to polish them after buying them, so the original shape will be the shape when they are finally collected.

But this is not the case when it is wrapped with a stone layer. The stone is worthless and can be carved at will.

Li Du read the news before that this kind of original opal has been quite popular in the market in recent years.

He had seen a pony with a body made of opal and its head, tail and limbs carved out of stone layers, and a flying eagle with its wings made of opal and its body carved out of stone layers.

Li Du was also quite excited when he got the news from Brende.

Now that this gemstone pit has been discovered, it belongs to him, and he cannot profit from it.

However, it is also good to be able to open your eyes. After all, gemstone pits are much rarer than pure opals, and one may not be found in a year.

Plus, he's not completely unprofitable.

Seeing Li Du showing interest in watching, Brende beckoned and said, "Come on, let's go and have a look. Maybe we're lucky and can dig one up?"

Gem pits are not densely packed in a small area, but there are such primitive opals in a considerable range, which may range from one hectare to one square kilometer or even ten square kilometers.

After all, for nature, the area of ​​a few hectares or a few square kilometers is too small.

Therefore, if someone discovers a gem pit, there is a high probability of finding rough opal in the surrounding area, and everyone will run to try their luck. This is a profitable place.

Li Du got into the car, followed Brende's motorcycle and killed him.

As a result, the more he drove, the more he felt puzzled. Sophie, who was lying on the window, asked curiously: "Why is this road so familiar? Isn't it where we stayed these two days?"

Li Du also thought so, but compared to when they were there two days ago, the gravel beach was much more lively, dozens of people gathered here, and some people were rushing here.

Brende stopped the car, waved to Li Du, and then wandered around in a hurry.

In the wasteland not far away, several people were shouting excitedly:

"Oh Fack Fack, I found a piece! Great, I found another piece!"

"Damn it, Smith is lucky, this guy actually found the gemstone pit, he made a lot of money!"

"This bastard is going to become a millionaire, see? They have searched for hundreds of rough opals before, and he is rich!"

"Millions? Dude, he could be a multi-millionaire! Hundreds of rough opals!"

Li Du rubbed his chin and looked at these people discussing excitedly with interested eyes. He felt that something was wrong. According to them, the pit of gems was located in this land.

But there are fart rough opals in this land, and there may be some gemstones, but there are absolutely no rough opals. Little flying insects have swept this area like a plow!

So, where do these rough opals come from? Where is the gem pit?

You must know that the Gem Pit is a name, not really a small pit. Even if the little flying insects searched for something, it is impossible not to find a single rough opal.

But now some rough opals have actually appeared, and there is a box in front of a strong man, and there are pieces of rough opals in the box, and he is guarding with a shotgun.

Under the sunlight, the stones and opals are inlaid together, emitting a strange light. Combined with the enthusiastic pickers, the atmosphere here becomes even more weird.

Li Du was thinking about what was going on, but the matter involved him.

Seeing his figure, someone immediately pointed at him and shouted: "This is the Chinese, he rented this place before us!"
