Jin Long and Xiao Yu entered the house, and at this time Jin Long did not return empty-handed, there was a walnut-sized thing in his hand, the color of gold and clear color, and the shape was very irregular, like a bone that had been gnawed by a dog.

Li Yifeng naturally also saw Jin Long enter the door, with professional sensitivity, and Li Yifeng even noticed the thing in Jin Long's hand.

"Doghead gold?"

Speaking of the dog's head gold, Wang Ding's eyes were hollow, and Li Yifeng knew that this kid had never heard of the dog's head gold, so he took the opportunity to explain.

"This thing that your brother Jin brought back is a dog's head gold. Dog's head gold is a kind of natural gold nugget containing impurities, mostly from the gold-rich meteor fall, gold rain geological period formed rich gold ore, this natural gold because the shape resembles the shape of a dog's head, so the name of dog's head gold. Jin Long, where did you get this dog's head gold? ”

Li Yifeng asked shallowly, and his footsteps followed. Jin Long's face was full of smiles, and Wang Ding only realized at this moment that if this kid didn't praise himself, it turned out that he had got a treasure.

I saw that the golden dragon walked quickly to the counter, put the dog's head gold on the table, and said proudly. "I can't say a word or two about this dog's head gold. He was sold by a friend of a friend of mine, and I said I was going to check it out two weeks ago, but I didn't have time for it. Just now I went from Dashang # Hai out of the sea, and I just passed, and when I saw this dog's head gold, I brought it back. Like this naturally formed dog's head gold, it is really a rare treasure, and it is really not easy to obtain. ”

Xiao Yu did not forget to add on the side. "Yes, Brother Jin's friend's friend specializes in mineral mining. I heard him say that this dog's head gold has to go through countless years of baptism, you see that the surface of this gold nugget is uneven, and the sediment in the cracks has not been completely washed, it looks ancient, and it is definitely worth a lot. ”

"If it's real doghead gold, it's naturally worth a lot of money. In the Qing Dynasty, according to legend, the Empress Dowager Cixi sent people to find the dog's head gold but to no avail, but what about this dog's head gold...... Wang Ding, you take a look at this dog's head gold first. ”

Li Yifeng had something to say, but he still didn't speak, maybe he hadn't come out of the role of a teacher yet, so he wanted Wang Ding to have a golden palm on this dog. Wang Ding sighed, walked to the counter, and carefully painted the so-called dog's head gold.

In Wang Ding's eyes, this dog's head gold should be said to be a golden lump, if it is just such a piece of gold, it is a little valuable, but what is the composition of the dog's head gold, Wang Ding does not know. Putting the dog's head gold into his hand, Wang Ding felt that its weight was not too heavy.

"It's not pure gold in this dog's head gold, is it?"

"It's not." Jin Long explained, "There are three kinds of dog's head gold, including gold-clad stone, stone-clad gold, and gold-clad water. This piece is a gold-clad stone, and there should be a stone in the core, otherwise its specific gravity will not be right, and it is impossible for the all-gold to be so light. ”

Li Yifeng added, "Doghead gold is not pure gold, the purity is generally about 70%, and the impurities are other metals, some are copper, some are silver or iron, etc. This piece, judging from the appearance material, should be the gold clad stone that Jin Long said. However, at present, there are many imitation doghead gold practices on the market, and the key to making doghead gold by themselves is to make huge profits. ”

Hearing this, Wang Ding has a general understanding of the dog's head gold, and the key to the appreciation of the dog's head gold is simple, which is to see what is the internal structure of this thing.

Li Yifeng handed the magnifying glass to Wang Ding at this time, and Wang Ding took the magnifying glass and appreciated it. The master leads the way and practices in the individual.

Wang Ding pinched the magnifying glass in his hand and pushed it into the dog's head gold, at this time he had quietly opened the perspective with the help of the jade brand aura to moisten the pupils, once the perspective was opened, Wang Ding pointed through the magnifying glass and the surface of the dog's head gold, and looked inside.

At this look, Wang Ding was surprised to find that as soon as the line of sight penetrated a few millimeters of thickness, the gold layer on the surface passed, and inside was a white pebble, and the strange thing was that the surface of this pebble had traces of corrosion, as if it had been bitten by insects.

Another suspicion is that the transition between gold and pebbles is too straightforward, and although the two are very tightly attached, they are separated from the river water, as if they were cast in a later period, but they are not natural.

turned the dog's head gold in a different direction, this time Wang Ding finally came to a conclusion, this thing is a fake, because from this angle into it, he saw that the gold clothes on the surface were divided into three layers, the bottom layer of which had a cut sharp corner, and the pebble surface on this side had obvious carving marks, at first glance, it was made by hand, and it was definitely not made by nature.

When he put down the magnifying glass, Wang Ding already had a plan in his heart, and even the production process of this piece of dog's head gold was guessed.

"This thing weighs about half a pound, right?" Wang Ding shook it and asked with a smile, "Brother Jin, how much do you receive?" ”

"Hehe, your estimate is very accurate, I have weighed this thing, two hundred and fifty-six grams, seventy percent of the same volume of gold plus the weight of pebbles that can be wrapped is also so heavy." Jin Long smiled confidently: "A few days ago, someone offered 300,000 yuan to buy it, but my friend didn't sell it, because he promised to ask me to see it first, and I saw it, it was genuine, so I paid 250,000 yuan, and he gave it to me, which is very righteous." ”

"Two hundred and fifty thousand?" Wang Ding thought to himself, you were cheated by someone, and you counted the money for others to play. "Just such a thing, someone still paid 300,000? Are you still happy to spend 250,000 yuan to buy it back? Wang Ding was stunned for a moment, and he really didn't know what to say. He never imagined that a piece of dog's head gold was worth so much. Even a piece of pure gold walnut is far less than 250,000 yuan. For a while, Wang Ding couldn't laugh or cry: "Pure gold is only about three or four hundred grams, its purity is only about seventy percent, and there is a stone in it, it is worth a thousand yuan a gram?" ”

"Huh. Wang Ding, what do you know? This dog's head gold is a rare work, but there is a historical value here. There are very few dog-headed gold in the world today, and it is a treasure formed by nature for thousands of years, and its value far exceeds that of gold. ”

Xiao Yu despised it, and the golden dragon was also on the line.

"Wang Ding, I said don't underestimate this small thing. Dog's head gold is adsorbed and aggregated by microorganisms, and it may take millions or even tens of millions of years to form such a lump thing. ”

"Ah, it's going to take so long, so I'll say less." Xiao Yu said apologetically, but continued to sarcastically mock Wang Ding. "Now you know what to say, right? It will take tens of millions of years. ”

Wang Ding became the target of public criticism, but Li Yifeng did not say a word. Until now, Li Yifeng is still holding the dog's head gold and looking at it, but Li Yifeng is not sure whether the dog's head gold is true or false at this time.

To say, Li Yifeng, an imitation of dog's head gold, has seen it and found a lot of fakes. But this piece, whether in terms of the luster of the appearance, the feeling of the hand, and the weight, can be called genuine.

"Wang Ding... I think it might really be the real thing. ”

Li Yifeng said his worst opinion. His words were dissatisfied, and Wang Ding took the opportunity to say the same.

"Brother Li said that it may be genuine, then I know that the second half of Brother Li's sentence is that it may also be a fake. So is it true or false? ”

Wang Ding pretended to be profound, so that the three of them also looked at him at the same time.

Xiao Yu looked very excited, slapping Wang Ding in the face was something he would dream of in the past few days, "What? Do you still want to express your opinion, but when your opinion is published, we can just ignore it. ”

"Ignore it or not, it's okay to listen to it." Jin Long's words were even more lethal, and he hid a knife in his smile.

Wang Ding knew that Xiao Yu and Jin Long looked down on themselves, so they didn't have to worry about their face at all, and looked at Jin Long for a while, Wang Ding affirmed: "Brother Jin, this dog's head gold is not made of natural ghosts, it will take millions of years, in my opinion, it is a high imitation, something that can be made in a few days." I don't know if you brought it back today, did you test our eyesight, or did you get an eye-beating? ”

"What? You say it's fake? The golden dragon's smile faded, and his expression became unkind.

"Huh." Xiao Yu couldn't help laughing, and glared at Wang Ding with disdain while laughing: "Wang Ding, I said that you didn't think you were amazing last time you picked up a baby." This dog-headed Brother Jin Li and Brother Jin both said that it was genuine, but you said it was a high imitation. Do you understand? ”

Wang Ding's judgment was called Li Yifeng at this time, and he didn't believe it, he picked up the dog's head gold, and couldn't help but look at it again.

"I say it's fake, it's fake. Believe it or not, my word is here. Moreover, I can make the same kind of koshead gold. ”
