The original jadeite is a good black sand gambling stone, the gambling stone is good, the water is long, and there is an emerald green color, but due to the green fog or gray fog that appears near the reductive secondary biochemistry of the epidermis, the gambling stone appears in the bottom gray, dark color, and blue phenomenon in the wiping mouth and window opening parts, which covers up the color characteristics of the original jadeite.

Therefore, the valuation of this kind of gambling stone is often low, and the selling price is not too high.

However, once it is cut, the part of the original jadeite that is not affected by the reductive secondary chemistry inside is likely to be of all kinds and colors, and the value will increase greatly, and the possibility of gambling is extremely high.

This kind of gambling stone often appears in the black Wusha gambling stone with a relatively large volume of gambling stone wool, and the mouth can not only see the secondary green mist, but also see the original green appearance.

Obviously, Yushan's second black sand gambling stone, this is the case, Zhang Menghu's old fox also said just now, these two pieces of black sand yarn they have opened their mouths and seen the internal performance.

And now, Yu Shan also checked the internal situation through the window here, and the Zhang family actually did a bit too much, just on a large black black yarn, they opened four windows.

And from these four windows to check the internal situation, the fog they see all gives people a dark feeling, which covers up the color characteristics of the original jadeite inside, so that the Zhang family's gambling stone master has an error in judgment.

"The species and color are good, but it's a pity that there is too little jadeite inside, but ......" Yu Shan could only look at the original stone and smile bitterly.

This piece of rough stone is really too big, and the piece of more than 400 catties that Yu Shan encountered just now is very big, but compared with this one, it is definitely a small thing.

This piece of black Wusha is favored by the Zhang family, it is definitely not without reason, the first is because it is black Wusha, as long as there is green black Wusha, the possibility of good quality is very large, in one is, this piece is a rare giant, and the appearance of the performance is not bad.

Therefore, this piece of black sand weighing more than two tons, even if it is opened with four windows, no one thinks it is too much, after all, its size is too big.

That is, because the size of this piece of black wusha is more than 2,000 kilograms, and the original price is 30,000 per kilogram, which is 60 million.

The rough stone without an opening is worth 60 million, and how much jadeite can be solved in it to return to the original cost?

Although Heiwusha is an old pit species, there is a great possibility of opening Gao Cui, but this is just a possibility, before it is unlocked, who knows what the internal performance is?

Therefore, after the Zhang family opened four windows and saw the poor performance inside, they did not dare to act rashly, even if his family had money, 60 million was definitely not a small amount of money, and it could not be wasted casually.

In the gambling stone industry, if one of the 60 million is not careful, it may make a splash and disappear.

Therefore, after meeting Yu Shan, the Zhang family had crooked thoughts, thinking that maybe they could find a pick-up man.

At this time, even Yu Shan, seeing the internal situation, was a little dumbfounded, there was jade in it, and it was also high cui, but it was too small, Yu Shan really didn't know, the jade inside was worth 60 million.

Of course, through rough estimates, the possibility of preserving the principal of this rough stone is still very large, otherwise, Yu Shan would not agree to gamble with a drothel.

Now, Yu Shan's main task is to estimate the weight of the jadeite inside, and then accurately describe the water and color of the jadeite.

Up to now, Qian Xiaohao's valuation is not very accurate, and it is still necessary for a veteran like Qian Kaiyuan to come out to judge accurately.

Yu Shan wrote down some data and handed it to Qian Xiaohao, Hei Wusha is worthy of being Hei Wusha, and the internal jade performance is definitely good, but I don't know if it can exceed 60 million.

The data was handed over, and Yu Shan didn't bother, he looked at the third piece of black black sand.

This is another piece of reductive, secondary biochemical black sand gambling stone, this piece is obviously like a trap, is a piece of poor quality of the rough stone, such a rough stone, can get back the cost of the possibility is very small.

Reductive, secondary biochemical strong black black sand skin gambling stone, mainly appear in some small volume of black black sand gravel stone wool, almost the entire jadeite gravel inside and outside, are subjected to reducing secondary biochemical effects, often after cutting, the overall jadeite wool is covered by green mist, the color is gray, dark, blue.

If it is a black sand jadeite gambling stone with good quality of original jadeite, there is a natural emerald green color, delicate texture, and good planting.

But this piece of fog so seen, as the background color gray, dark, blue, covering the original green, so that the value of jadeite can not be reflected, gambling stone gambling is not likely, but will collapse.

Generally, the finished product made of this kind of gambling stone wool will be used for jadeite B goods treatment, after strong acid erosion, the secondary dark green (green mist) can be removed, so that the original color of jadeite is revealed, but due to artificial treatment, although the color is very good, there is no value.

This is a typical piece of poor quality of primary jadeite black sand jadeite gambling stone, the internal primary jadeite is white, coarse, opaque, mainly in the low-grade bean field, white ground green jadeite wool.

After the reduction and secondary biochemical action of this rough stone, the color will show oil blue-green, the transparency has also been improved, and the texture is relatively delicate, which has improved its own value, but because it is oily green and blue water, the increase in gambling is generally not too large.

It can be seen that the variables of the black Wusha gambling stone are very large, and it is necessary to fully understand and analyze the gambling stone, especially to correctly distinguish the primary color and secondary color (fog) in the wool, and draw the correct conclusion according to the analysis of the reductive secondary biochemical strength of the black Wusha gambling stone.

Judging from the characteristics of this black sand gambling stone, the green that appears on the wipe mouth is only the green shown by the green fog layer, not the real natural green, if it is cut, it may collapse, so you need to be especially careful.

As the saying goes, "it is difficult for a god to break an inch of jade", this is really good, at this time, even if Yu Shan can see the internal situation, he is a little overwhelmed.

Therefore, when buying jadeite gambling stones, especially black sand gambling stones, everyone should be cautious.

Of course, if you correctly understand the characteristics of the black Wusha gambling stone, and correctly distinguish the difference between green mist and native green, there is also a great opportunity to gamble on the black Wusha gambling stone, that is, the so-called "high risk has high returns".

This time, Yu Shan encountered such a high-risk, high-yield gambling stone, I have to say that the Zhang family's gambling stone master also has two brushes, if it weren't for the performance of this small gambling stone, they would not have been able to pick it out.

Since it has been picked out, there is naturally a little reason, and now it is thrown out for Yu Shan to identify, definitely because after opening the mouth, he saw that the internal performance was not good, so he thought that this was a piece of 100% gambling material, which was used to pit Yu Shan.

However, the truth is often unexpected, such as this one, although the internal performance is not good, but it can't stand the jadeite inside.

Due to the green fog outside, even if they opened a few small windows, they had no way to completely figure out how much original jadeite there was inside, which happened to be cheaper than Yu Shan.

Yu Shan was able to see through the green mist on the outside and directly see the jade inside, so he could correctly judge the value of this rough stone.

"The performance of the opening is not good, and the jadeite inside is not good, but it can't stand the large proportion of the occupation, and the color is dark, this is the oil green jadeite, which is not bad." Yu Shan secretly made a judgment.

The reason why Yu Shan is satisfied with this kind of performance is because under Qian Kaiyuan's reminder, Yu Shan knows that this piece of rough stone is easy to return to its original value.

Because this rough stone is only a little more than five kilograms, but the jadeite inside is more than four kilograms, so many jadeite, even if the price of the rough stone is more than 30,000, it is only worth 150,000, and how much is four kilograms of jadeite of oil green species worth?

Even if Yu Shan doesn't understand the jade market, he knows that four kilograms of oil green seeds must be more than 150,000.

How many bracelets can be produced from these four kilograms of jadeite?

Yu Shan calculated a little, even if the price of an oil green bracelet was sold for twenty or thirty thousand, the price of ten bracelets would be more than three hundred thousand.

Although there was such a judgment, Yu Shan did not make his own decisions, but discussed it again with Qian Kaiyuan and the two masters.

At this time, Yu Shan knew that in the oil green jadeite, there are primary oil cyan and secondary oil cyan.

The primary oil cyan jadeite is composed of pyroxene minerals such as iron-containing omphamene, because it is Fe2+ color, the green is often gray and dark, thus reflecting the oil cyan.

The secondary oil cyan is mainly infiltrated and impregnated by some chlorite-like clay substances, along the jadeite mineral interstitial and micro-cracks that make up jadeite.

Due to the different causes of color, the value of the two also has obvious differences, the original oil cyan jadeite belongs to the middle to high-grade jadeite, and the price is higher.

The secondary oil cyan jadeite belongs to the middle to low-grade jadeite, and the price is relatively low.

Yu Shan can be sure that this is a native jadeite, so at least it belongs to the middle to high-end jadeite, plus the jadeite inside this rough stone is soft in color, and the color is biased towards a more beautiful blue-green, so the price should be higher.

Moreover, Yu Shan also found that in the most central position of this piece of jadeite, some oil green jadeite, almost reached the ice species, the texture was delicate, and the color became very uniform, so the price should be more expensive.

After checking it, Yu Shan also relaxed.

Qian Xiaohao muttered to Qian Kaiyuan on the side: "This is a native cyan jadeite? ”

"Yes, the primary oil cyan is the color that appears in the jadeite, the color is uniform and soft, the color tone is blue-green under the transmitted light, and it will not diverge and fade.

Although this kind of jadeite cannot be said to be an ice species, the ice oil is also very beautiful, so such jadeite often has a delicate texture, uniform color, and will show a soft 'fluorescence' in the light. Qian Kaiyuan said with a smile on his face. (To be continued.) )
