Liu Yiyan seemed to see the thoughts in the hearts of the two, pointed to the tabletop, the skin near the edge was also jet black, and it was also a rough stone covered with a layer of wax shell, and said with a smile: "You can open this piece again and take a look." ”

After Chen Songhu stretched out his hand suspiciously, he couldn't help but shrink his pupils.

Yang Hao was also stunned when he saw the rough cut that Chen Song had opened.

On both facets of the rough, the bottom is grayish-white and looks dirty, and the green on the top is uneven, dry in some places, and in some places the green is intense but with black spots.

"Why is this happening?"

Chen Song looked at this piece of rough stone that looked like it was top-notch and the water in it was also very good, but the bottom was dirty, the water was dry and colorful, and there were even some gaps in the water in many positions, and he couldn't help but ask.

"It's a variant!"

"Mutants?"

Chen Song and Yang Hao looked cloudy.

Aren't all jadeite species fixed?

Isn't it all the same texture after unraveling?

"Yes, it's a variant. ”

Liu glanced at the puzzled expressions of the two, and said with a smile: "It's a piece of jadeite rough, all aspects of the appearance look good, after rubbing a piece of skin, the water is also very good, but after the result is unraveled, many positions inside have become worse, this situation is called a variant; ”

"Master, I understand!"

Yang Hao said with some excitement: "The change of germplasm inside this rough stone is due to the geological environment in which the rough stone is located and the different geological processes it is subjected to, which leads to the same piece of jadeite with different structural characteristics, that is, the jadeite rough will undergo structural changes at each stage of formation, and even the structure will be reconstructed, so there will be a variant." ”

Liu Yiyan nodded and said with a smile: "That's right, for example, a piece of jadeite rough stone, in a certain jadeite vein, half of its volume is subjected to more stratum pressure than the other half of the volume, and the temperature of the part with large force will be slightly higher, which causes the texture to be uneven on the same stone, resulting in two species." ”

Chen Song nodded in understanding.

"The black black sand skin is a darker black and green, most people see this kind of skin shell and think that it will have a darker green part inside, and even can show a full green jadeite, but the black black sand skin jadeite rough stone changes very much, like the one in front of you, after unlocking, the green inside with black spots, also has a very dry green, and the bottom inside is also very dirty. ”

Liu Yan sighed: " The varieties of black black sand are very magical, some of them are only a few centimeters apart, it is two worlds, so the bottom is very important, even if the seed is tender, but the meat is delicate, no cotton and no impurities, it looks warm and shiny, and it can also make up for the defects of the tenderness, in addition, there is a kind of black black sand, which is not found in other rough stones, called through, manifested as the original stone skin color black with pine flowers, the pine flower particles are thick and convex, irregularly arranged, the color is bright, the pine flowers can not see the seed water, and the seed water on the pine flowers is very good, this kind of stone will also appear to solve the bankruptcy, or the solution of the two extremes of the rich rival country。 ”

After thinking about it, Liu Yiyan said: "There is an extremely valuable experience in distinguishing in the Xiangyu world, that is, the wax shell is stuck on the skin shell without sand skin, it looks very hard and not easy to fall, where there is sand, the wax shell is easy to fall, and there are some that are easy to fall off when they are soaked in water, which is mostly the rough stone produced in Houjiangchangkou!"

Liu Yiyan pointed to the light gray jade rough on the table, and suddenly asked, "What is this piece called?"

"Elephant skin!"

Chen Song and Yang Hao replied in unison.

Liu Yiyan smiled and said: "The elephant skin is similar to the old elephant skin, it is light gray white, with the appearance of elephant skin, rough and wrinkled, it looks like there is no sand particles, but it is very rough, and it feels prickly when touched, which is a typical manifestation of weathering, and it is also a kind of old performance, this kind of skin is a native sand shell, good texture, easy to unravel, after cutting, the ice bottom and glass bottom are mostly seen, it is the characteristics of the skin shell of the existence of high-quality water materials, mainly produced from the old Pa Kang. ”

The top half of the elephant skin is turned open, and both facets are clean and flawless glass bottoms, exuding a cool sheen.

Chen Song and Yang Hao were a little surprised.

It seems that as long as you remember the characteristics of the weathered shell, you can roughly know the probability of something good in the rough stone after you see the jadeite shell in the future.

"What's this piece called?"

Liu Yiyan pointed to the yellow-brown jadeite rough shaped like tree bark, with a weathered shell that was dry and brownish.

"Denakapi. ”

Chen Song and Yang Hao replied in unison again.

It seems that they have indeed memorized the characteristics of various weathered crusts during this time.

Liu picked up this piece of Denika bark with a smile on his face, and said with a smile: "This weathered shell looks very similar to the bark of the Denika tree here, so it is called Denika bark, it can also be called old bark, it looks rough, it looks very loose, pimples, wrinkles, this is a kind of old rough stone undergoing high-pressure extrusion, but the essence is very hard, its color is generally lighter, the sand hair is yellowish-white, the feel is thorny, after cutting, there are more white water bottoms, most of them contain positive colors, the water color is better, the color content is high, it is easy to cut up, and the old meat is fine. It is also a common ice type of good material, and it is mostly produced in the Damakan area. ”

Separate the upper and lower parts of the rough and place it on the table with the cut side facing up.

A large piece of Zhengyang green is exposed on the two sections, the bottom is clean and clear, and the distance and size of the green can be directly seen, and the texture is very close to the glass species.

"This piece of material will rise sharply after unraveling, and it will also rise sharply after polishing, and the water will be raised by one level directly!"

Liu Yiyan's eyes were soft, he put his hand on the rough facet, and slowly stroked the green on the facet, showing a look of remembrance on his face.

Chen Song and Yang Hao were taken aback.

How else could there be such a situation?

Without waiting for the two to ask questions, Liu Yan Yan said directly: " Such a material has a soul, its crystal particle boundary produces a fine crystallization effect, so that the jadeite mineral particles become slightly invisible, but can directly block the refraction of light, the state of the original stone makes people feel that it is high ice, once it is made into a finished product, it can effectively eliminate the existence of pores between the jadeite mineral particles, so that the jadeite texture becomes delicate and round, the structure is more compact, and the transparency is greatly improved, revealing the original real seed water, which belongs to the underestimated Tibetan edge material, the finished product state is directly exposed to the edge, the whole body is crystal clear, rich in spirituality, and the value of the original stone has increased several times！”

Liu stopped his hand at a glance, and sighed with a little red in his eyes: "Everything is the same, being a human being, how can it not be like this!"

Chen Song and Yang Hao were secretly shocked, and at the same time secretly curious.

What shocked me was that this material could change from a high-ice species to a glass species after it was finished.

What is curious is why Master Liu Yiyan is suddenly so sad.

Yang Hao asked cautiously: "Master, does this material belong to the high ice species or the glass species?"

"Does it matter?"

Liu Yiyan stretched out his hand and rubbed his eyes, looking at the two with a smile on his face.

“......”

“......”

The two of them were speechless.

Liu Yan said leisurely: "This question depends on how you think about it!"

"Understood!"

Both nodded at the same time.

Liu Yiyan may not be in a very good mood because of the table, directly pointed to the piece of yellow skin such as pineapple, thin skin, slightly transparent jade rough on the table, said: "This kind of pineapple skin, you can see whether it contains color in the light, if it is colored, after cutting, the green and yellow flavor is enough, bright and lively.

Then pointed to the surface like a layer of white powder covered with the jade rough, said: "The yield of this lime skin is very high, it is mainly produced in the old field area, the third level of the Houjiang field area and the small field area, most of the small pieces of sand are wrapped in a layer of lime powder, brush off this layer of white powder is white sand, this is the surface weathering performance, produced in the old field area after cutting the glass bottom is the majority." ”

Pointing to the surface of the yellow-white, thin skin, the color is milky yellow and thin, and the rough stone with high permeability, he said: "This kind of stalagmite skin belonging to the middle of the mountain and half of the water, after unraveling there is green, then green and warm, it is very distinctive on the bottom of the white water, Damakan is the most, and the old field area also has." ”

Pointing to the surface of the skin shell resembling bacon, the surface is extremely thin, smooth and transparent rough stone, said: "This kind of bacon skin is water stone, the skin shell is thick and thin, the bottom of the seed is thick and fine, generally opaque, it is a medium jadeite, there are more production sites, but it is rare to have emerald color." ”

......

Liu glanced as if he was venting, and the more he spoke, the faster he spoke, Chen Song and Yang Hao frowned, and they could only remember the key points.

Yang Hao regretted a little why he didn't bring a pen and a notebook.

In the end, Liu Yan let out a long sigh of relief.

Picked up the piece of leather shell on the table, some of the sand particles fell off, revealing the flesh, and the leather shell was a mix of yellow, white, and red rough stones, and said slowly: " This kind of desanding skin, most of the shells are easy to fall, the above desanding is due to not completely weathering, resulting in the existence of attached sand in the shell, shedding sand, the coarser the sand on the weathered shell, the coarser the species, the finer the sand, the finer the species, this is a double layer of sand shell, is a typical variety of symbiosis between the primary sand shell and the secondary sand shell, there is a layer after removing a layer, the color is mostly a layer of white, two layers of yellow and red, some of the desanding skin will slowly turn white, some are still yellow or reddish yellow, most of the yellow shell surface is easy to drop sand grains with yellow and yellow-red species of good, such a shell is easy to ice species, glass is a good material, its value is expensive, the main source is Dongguo and the old field area. ”

Seeing that Liu Yiyan finally slowed down his speech, both of them secretly breathed a sigh of relief.

In addition to a black, gray, yellow-brown and other colors, there is also a green skin color, called skin green, on the skin of the jadeite rough, its green is to grow with horizontal characteristics, the price of this jadeite rough is generally relatively high, because the skin green rough is the easiest to cut out of green, many legendary calcite stories often occur on the skin green rough, with this green rough risk is relatively high because the skin green is very confusing, you should pay special attention to this. ”

Liu Yanyan directly turned over the green rough stone on the tabletop, and saw that the cut surface was covered with Spider-Man-like cracks, no color at all, and it was so white that it was dazzling.

"Consolidate well, if there is anything you don't understand, come to me in the courtyard. ”

After Liu finished speaking, he looked at the two teenagers with frowns tightly together, shook his head, and turned around and walked out of the room.

Xiangyu has never relied on rote memorization, each piece of rough stone is very different, even if it is the same piece of material, it can be ever-changing.

If you remember the weathered shell characteristics on the jadeite rough and you can completely solve it, then there will not be so few jade masters!

What they teach is only common sense, and in the end it is up to them.

What he can do is to cultivate the two of them have a sense of jade and form their own way of identifying jade.

Because there is never a specific means to distinguish jade, there is no shortcut at all, only by seeing more, researching more, and cultivating the feelings, can we truly understand jade.

Even if they are the same jade masters, the jade methods of each other are very different, and they are different!

Some people can tell by looking at the subtle features on the weathered crust of the rough stone, some people can tell the rough by the touch of the rough stone in their hands, and some people can even know the quality of the inside of the rough by listening to the sound of hitting the rough stone......
