Li Du pulled up Alicia and wondered, "Gem pit? What is that? ”

Brende was about to speak, but Alicia punched him and said angrily, "Do you want to kill us? Why do you still have the handlebars loose when driving here? ”

Brende was not angry after being punched, and he was a good old man like his cousin Stephen. Pen, fun, and www.biquge.info

Facing his angry wife, he sneered: "I was so excited just now, let's go to the gem pit, we won't get anything if we go late." ”

Sophie wondered, "Gem pit? What is it? Are there a lot of gemstones? ”

Li Du shook his head and said: "Yes and no, the gem pit of opal refers to a lot of rough opals. ”

The essence of all natural mineral gemstones is silica, and opal is formed because of the ultra-high temperature formed in a certain area due to volcanic eruptions or epidemic impacts about hundreds of millions of years ago, and the stone was melted to purify silica.

The silica melts into a solution and then flows like magma into the crevices of the inland strata and into the empty ore areas for deposit.

In general, this deposition occurs at a depth of about 40 meters above the surface, and the sediment is about one centimeter thicker every five million years, and the silica slowly solidifies together.

After this stage, one to two million years later, as the sediments begin to solidify as the climate changes, the opal is the part of silica that does not adhere to other sediments and hardens over a considerable period of time.

Among them, when the silica liquid condenses slowly, it may not be completely separated from the stone in the outside world, and may merge with the stone or dust.

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

Of course, opals can have such beautiful forms and such rich patterns, and there are other reasons, which are very complex physical processes, and Li Du can barely understand them.

The gem pit was acquired when he learned this information, and the knowledge of the rough opal was also acquired at that time.

The conditions for the formation of a rough opal are not the same as the formation of a pure opal, and almost all silica solutions come into contact with the stone from the outside world during the flow and condensation process.

However, only some of them form rough opals, and most of them are pure opals, which also involves a complex physical process.

It is during this physical reaction that the difference between rough opal and pure opal emerges, pure opal tends to appear alone, and rough opal appears in large quantities.

Rough opals are less valuable than pure opals because they are often combined with some ugly stones.

Gemstones are worthless if they become ugly.

However, with the development of modern science and technology, the value of rough opals has been enhanced.

Some machines can polish off the outer stone layer in the rough opal to expose the opal inside, and some will carve the stone layer to process a valuable image.

Both of these methods can increase the value of rough opals tenfold, especially the latter, because the opals themselves are so precious that people are reluctant to polish them after buying them, so what shape of the original is what shape is finally collected when it is collected.

But this is not the case after being wrapped in a layer of stone, the stone is not valuable, and it can be carved casually.

Li Du read the news before, and in recent years, this kind of original opal has become quite popular in the market.

He had seen a pony with an opal body and limbs carved out of stone, and a flying eagle with opal wings and a body carved out of stone.

After getting the news from Brende, Li Du was also quite excited.

Since this gem pit has been discovered, it belongs to someone else, and he cannot profit from it.

However, it's good to be able to open your eyes, after all, gem pits are much rarer than pure opals, and you may not find one in a year.

In addition, he is not completely unprofitable.

Seeing Li Du showing interest in watching, Brende beckoned: "Let's go, let's take a look, maybe we are lucky enough to dig one?" ”

Gem pits are not concentrated in a small area, but in a considerable area where this primitive opal exists, perhaps one hectare or even ten square kilometers in this range.

After all, a few hectares and a few square kilometers are too small for nature.

So if someone finds a gem pit, there's a high probability that they'll find rough opals in the surrounding area, and everyone will run to try their luck, and that's where the profits are.

Li Du got into the car and followed Brende's motorcycle to kill him.

As a result, the more he opened, the more puzzled he became, and Sophie, who was lying at the window, asked curiously: "Why is this road so familiar?" Isn't that where we've been for the past two days? ”

Li Du also thinks so, but compared to the time they were two days ago, it will be a lot more lively on the gravel beach, dozens of people have gathered here, and some people are rushing here.

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

In the wasteland not far away, several people shouted excitedly:

"Oh Fakfak, I found a piece! Great, I found another piece! ”

"Damn, Smith is lucky, this thing actually found the gem pit, and he made a fortune!"

"This bastard is going to be a millionaire, see? They had already searched for hundreds of rough opals, and he had made a fortune! ”

"Millions? Man, he could become a multi-millionaire! Hundreds of rough opals! ”

Li Du touched his chin and looked at these excited people with interested eyes, he felt that it was wrong, listen to their meaning, the gem pit is in this land.

But there is a fart rough opal in this land, and maybe some gems, but there is no rough opal, and the little flying insects have already swept the 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 small flying insects have omissions when searching, it is impossible that not a single rough opal has not been found.

But now there are some rough opals, and one of them is a strong man with a box in front of him, and in the box is a piece of rough opal, and he is guarding it with a shotgun.

When the sun shines, the stones and opals are inlaid together, giving off an eerie glow, which, combined with the enthusiastic pickers, makes the atmosphere even more eerie.

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

Seeing his figure, someone immediately pointed at him and shouted: "It's this Chinese, before us, this place was rented by him!" ”
