Lin Cheng and Wang Ruyan entered the rough stone trading hall.

As soon as I entered the hall, I saw a huge jasper rough.

However, although this jasper rough is very large, the jade quality is quite average.

It belongs to the relatively poor jade quality.

It's all about being big to bluff people.

"Wow, that's a big jasper rough stone."

Wang Ruyan was shocked by the huge jasper rough.

She leaned over to the jasper rough and touched and looked and looked.

Finally, he turned his head to look at Lin Cheng.

"I'll test you, can you recognize the origin of this jasper rough?"

"It's still a test, this is Manas jasper."

Manas jasper is produced in the territory and is the main production area of domestic jasper.

However, the quality of domestic jasper is relatively average.

Not only is the jade coarse, but it also has a large number of black spots.

In contrast, the texture of Russian jasper is very good.

But when it comes to white jade, it is still the best quality of domestic Hetian jade.

Far from being comparable to Russian white jade.

However, because high-quality Hetian jade is too scarce, a lot of Russian white jade has been introduced as a substitute in recent years.

"I don't see it, you're quite knowledgeable."

"Jade is an important branch of antiques, how can I not understand it at all."

"How can it be the same, many jade treasure experts don't know much about the origin of jade."

Jade is a large classification in ancient texts.

And there are many types of jade involved.

Some experts in the appreciation of two knives only study the carving, modeling, color, weathering and so on.

There is a lack of research on the origin of the most fundamental material of jade.

"How can they compare with me, I like to dig into the roots of antiques, from the process to the raw materials."

"It seems that you don't know a little bit, and the responsibility of checking it will be handed over to you."

Wang Ruyan took Lin Cheng's test just to see Lin Cheng's level of jade.

In this test, I found that Lin Cheng's level was very good.

Passing through the rough stone trading area such as Hetian jade and the four famous stones, Wang Ruyan pulled Lin Cheng straight to the jade rough area.

In this primitive trading hall, it also happens to be the most lively jade rough area.

Because of the trend of gambling stones, many people come with the mentality of buying rough stones and gambling.

Some stalls with a large amount of rough stones and cheap are even more incomprehensible.

"Why are so many people here, let's find a booth with fewer people to see."

Wang Ruyan didn't want to crowd people.

So he took Lin Cheng and walked to the stall with few people in the corner.

In the corner of the booth, there are a variety of rough stones.

Most of these rough stones have a dark shell that looks like ordinary stones.

At the front of the stall, there are some rough stones with open holes in the outer shells, or small pieces of the shells cut open.

This kind of rough stone is called window material, which means to open a window.

Through the small hole that is opened, or a small part is cut, the jade inside can be observed with a strong flashlight.

However, this kind of window material is a great test of eyesight.

A lot of the window material looks very good, and when you cut it, you find that the rough inside is completely different from what you see.

Because before cutting, the skin shell will affect the light, and then affect the judgment of the internal color and water head of the jadeite rough.

And jadeite plays with color and water head.

Many people who have just started to play gambling stones always feel that this kind of window material is easier to grasp.

In fact, after playing more, you will find that this kind of window material is the big pit.

Wang Ruyan was staring at the window opening materials carefully.

She also started to play gambling stones not long ago, and she has the same idea as ordinary people.

"What are you doing with the window material? It's not easy to grasp. ”

"It's hard to grasp, the windows are open, and you can see the jade inside through the opening."

"Think about the window opening materials you have played, are they basically all broken?"

"This ······"

Wang Ruyan thought about it carefully.

It seems that this is really the case.

I have gambled on more than 100 window opening materials before, but none of them have been cut up.

The best thing is to cut it flat.

The rest collapsed.

It can be said that the loss is miserable.

Of course, the little money that bought the rough stone was a drizzle for her, a rich lady.

She's purely for fun.

"But I can't buy the material for the window, and I haven't cut the price."

“······”

Lin Cheng was speechless.

Is it that easy to gamble on stones?

Unless luck is against the sky, even if an experienced old bird comes to gamble on the stone, there is a great probability of losing the bet.

Those jewelry and jade firms involved in gambling stones have many cases of collapse every year.

"It's normal to gamble on stone cuts, but window opening materials are more of a trap."

"Traps? How to say. ”

"The window opening material is very important to the selection of the window point, and it is the window opening point selected by the master."

"But after opening the window, don't you think the experienced master won't take a look?"

"After they have seen it, the resources of good materials have been taken and opened, and the remaining window opening materials in bad condition will be taken out and sold."

“！！！”

Wang Ruyan's eyes widened in surprise.

I never thought that there would be such an operation before.

But I had to think about it carefully, but I felt that what Lin Cheng said was reasonable.

The feeling of initiation arises spontaneously.

Wang Ruyan stomped her foot angrily.

"Why am I so stupid, why didn't I think of this."

"It's really a big loss, and I've been practicing the skills of selecting rough stones all the time, and I want to show my might."

"You have to help me, you have to help me realize my dream of winning the gambling stone."

Wang Ruyan was like a girl who was spoiled by her boyfriend, pulling Lin Cheng's sleeve and shaking it gently.

Lin Cheng scratched his head.

Some don't have a lot of adaptation.

An unmarried Bai Fumei coquettishly told herself with a daughter with an oil bottle, is this to accept or not to accept?

"Okay, okay, I'll help you."

After Lin Cheng finished speaking, he squatted in front of the stall and picked up the rough stone.

Looking at the rough stones one by one, Lin Cheng glanced at the stones sitting under the stall owner's buttocks.

The stone was black and shiny.

Obviously, the stall owner has been used as a stool for a long time.

And from the outside, it doesn't look like a jadeite rough.

But Lin Cheng just fell in love with the black stone.

Lin Cheng didn't ask about the stone, but picked up a rough stone from the stall.

"Boss, how do you sell this rough stone?"
