Zhang Tianyuan didn't pay attention to these people, he was watched more times, and he didn't care about this time or twice, the most important thing now is to figure out this stone first, see how much it is worth, whether it is true, if it is really a big red robe, then even if it is two million, he will buy it, once this thing is carved, its value will not be low.

Of course, in order to avoid the suspicion of others, he still asked Zhanfei to bring that kind of small strong light flashlight, as well as magnifying glasses and other tools, and he had to use these things to make a look every time.

Because of this, every time it seems to others, Zhang Tianyuan uses a very orthodox method to detect the authenticity of the bloodstone, but what they don't know is that after Zhang Tianyuan just squatted down, he directly opened the word identification formula, and then used the word identification formula to judge the authenticity of the bloodstone.

"Really? Did I misjudge? This is not man-made chicken blood, but real chicken blood?"

I thought that as long as I opened the word recognition trick, I could tell at a glance whether this thing was real or fake, but the actual situation made Zhang Tianyuan a little surprised, when he opened the word recognition trick, he was surprised to find that this bloodstone turned out to be real, and those chicken blood red were also real, and it was not fake at all.

As long as it can produce dragon appearance, it must be true, this is the conclusion that Zhang Tianyuan has always summed up about the dragon phase, which is one of the three functions of his character recognition formula.

And this bloodstone has a dragon phase, which is enough to show that the bloodstone is real.

But Zhang Tianyuan doesn't believe in this evil, he is a more serious person. I thought to myself that it was possible that the dragon phase would also be wrong, so I used a multi-purpose method to comprehensively analyze, such as dividing the bloodstone into several parts. Observe them separately to see if there are any traces of splicing.

After all, in the antique counterfeiting. There is a fake method of splicing, and bloodstone can also be spliced.

After such an inspection, a shocking thing appeared, it turned out to be all true, but these dragon faces are a little strange, obviously the same stone, but there are hundreds of dragon phases, and there is only one possibility of this result, that is, this stone is actually not a whole stone at all. Rather, it is thought that it was put together with small bloodstones.

It reminded him of something he had heard mentioned before.

In recent years, with the overall heating up of the collectibles market, the value of bloodstone in Changhua in Linzhou has also risen several times every year. However, as the price increases, new methods of fraud have emerged. Recently, Boss Zheng, an investor in Jiangsu and Zhejiang who has many years of bloodstone collection qualifications, was almost defrauded of millions of yuan by a new fraud method.

In fact, it happened on a weekend last year, when Boss Zheng took pictures of a 3-meter-long, 0.6-meter-wide bloodstone sculpture, with exquisite carving and high blood content. The two parties agreed on a transaction price of 5 million yuan. In fact, according to the current bloodstone market, the price of a seal of the same texture will reach hundreds of thousands of yuan. Extrapolate accordingly. Boss Zheng felt that he had picked up a bargain.

However, after the on-site identification of the geology and mining experts of the Department of Geology and Mining of Jiangsu and Zhejiang Province, this bloodstone is the product of the latest fraud methods. It is made of hundreds of square chickens and bloodstones, and the actual value does not exceed 20,000 yuan.

According to the geology and mining experts who participated in the identification. Counterfeiters put hundreds of pieces of bloodstone in a mold frame and mixed in a large amount of organic glue. Pressed together into a piece, and finally trimmed the adhesive marks on the surface. This method is a recent development, and it is generally difficult for collectors who do not know the inside story to find traces of sticking.

Almost at the same time as this incident, there was also a bloodstone fraud case in Jiangsu and Zhejiang. A Wenzhou collector fell in love with a 12 cm high, 2.5 cm square bloodstone seal in a collection store, the texture is quite rare "big red robe", generally speaking, the collector of bloodstone with a blood content of more than 70% is called big red robe, not necessarily all red.

It turned out later that this "big red robe" bloodstone seal was also a new fake. According to the geology and mining experts involved in the identification, the counterfeiting method of this bloodstone is more lethal, and the counterfeiter takes the real bloodstone powder and presses it, and the density is very similar to that of natural bloodstone, and there is no difference between it from the surface alone.

According to the "Changhua Bloodstone Inspection Rules" issued by the Linzhou Municipal Quality Supervision Bureau, the common way to distinguish natural bloodstone from imitations is to observe the blood color and blood shape characteristics. Fake bloodstone patterns, unnatural colors, single tones, color blocks, ribbons are mechanically sluggish. The color of natural bloodstone has different shades, and the shape is natural and smooth.

But this method of counterfeiting makes it difficult for you to judge with guò method.

However, Zhang Tianyuan summed up some experience by himself, and he felt that there was still a way to distinguish between real and fake bloodstone. For example, carefully observe the traces of the joint, look for the joint seam and the bubble at the joint, observe whether the distribution of blood clots and patterns is continuous and natural, and observe the gloss, generally the fake bloodstone mixed with organic glue has a dark luster.

Of course, these methods don't make sense to him, he uses more powerful plug-ins, as long as the plug-ins come out, no matter how magical the fraud methods are, they can't escape his eyes.

Putting down the bloodstone in his hand, Zhang Tianyuan couldn't help but sigh in his heart, this bloodstone is the latest counterfeiting method used, no wonder even the dragon phase can deceive, because it itself is real, it is just a large piece of bloodstone glued with small bloodstone.

In fact, about the counterfeiting of bloodstone, there are not only these two methods, the most commonly used methods of counterfeiting are generally four, the first is the mosaic method, that is, on the surface of the stone, select a few eye-catching places, dig out a small pit of different depths, and then embed it with red mercury sulfide paint, wait for it to dry naturally, and then polish and wax.

However, there is no hierarchy of this embedded mercury sulfide, and the junction of the blood and Chang fossils is blunt in color and has no transition.

Then there is the impregnation method, which is more complicated, which is to coat the place where Changhua fossil needs to be coated with mercury sulfide, dry it in the shade and then coat it, and then dry it in the shade to make its blood slightly layered, and then put it in a transparent resin to impregnate it, so that the whole body is immersed and picked up to dry. Then use fine water and sand to light.

Fake bloodstone made in this way is easy to age due to the resin. Over time, the epidermis will turn yellow, which does not harmonize with the color of the stone inside. At the same time, the pores of the resin epidermis are relatively thick, and if you look closely with a magnifying glass, there is a little bit of fine rubbing on the surface.

The third method of slicing and peeling is only suitable for the seal material of bloodstone, and it is not very commonly used, so I won't say much.

The last method of falsification is called the topping method, which involves adding mercury sulfide to real bloodstone and covering the surface of the added part with a very thin layer of resin. It is finished after polishing.

This kind of method is to add blood to blood, which is undoubtedly the icing on the cake, and the value is greatly increased, and at the same time, there is a falsehood, a false and a true truth, so for a particularly good bloodstone, we must pay attention to and associate with the forger's methods when observing, so as to avoid the consequences of "carelessness in Jingzhou".

In fact, nowadays, many people do everything they can, and the methods of counterfeiting are also keeping pace with the times.

For example, bloodstone imitations

"Golden Red":

Vein quartz contains red cinnabar particles. It is named because it is often found on the top of gold mines. In addition to the United States, Jilin in China has also been discovered, and it is called "cinnabar jade" or "peony jade".

"Chicken Blood Jade":

First make Xiuyu crack, and then put it in red dye to color.

Splicing Bloodstone:

Glue the pieces of bloodstone with 502 glue. And then carved, this is the kind of fraud that Zhang Tianyuan saw today, but obviously the level of fraud of this thing seen today is better than simply bonding with 502 glue. I don't know what material is used, which not only makes the adhesive light and invisible. And it's also very beautiful overall.

Craft "Bloodstone":

Gray-black plastic is used as the ground, cinnabar powder or red organic pigment is blood. The exterior is coated with a layer of protective resin.

In fact, if you really want to talk about it, these are small things, and the really scary thing is that there are some stones, even experts have no conclusion, some people say they are true, some people say they are false, and you are completely confused.

Zhang Tianyuan heard Dou Xiaoling say it on the phone before coming to Changhua.

A collector spent a huge amount of money to buy the "bloodstone", one day encountered ice and fire, one side is the national television "treasure hunting" column invited by the domestic experts, the identification is fake, the other side is the authoritative testing agency - China Geosciences Jewelry Testing Center, the identification is true.

The two experts came to very different conclusions, which made the collector and laymen like me look dazed and even more curious. Whether this "bloodstone" is true or false, their TV station is looking forward to more experts to understand the stone and let its truth be revealed to the world.

I remember an intriguing quote from a senior collector: "95% of people spend 95% of their money to buy 95% of fakes." ”

This statement highlights the chaos of the collector's market. Therefore, Zhang Tianyuan still has to remind collectors to Taobao in this circle, but if you need more eyes, it will be more than worth the loss.

"What happened later?" Zhang Tianyuan was particularly interested in this matter at that time, and wanted to know what the situation of this bloodstone was.

According to Dou Xiaoling's description, the truth of this story was finally revealed.

"180,000 yuan was bought as an artificial stone?" the more Ms. Wu thought about it, the more entangled she became. Walking out of the recording site of the program, Ms. Wu's mind was blank. After calming down a bit, she dialed her husband's phone. In the afternoon of the same day, Ms. Wu and her husband came to the Jewelry Testing Center of the National University of Geosciences with this piece of "bloodstone".

Interestingly, the person who received Ms. Wu at that time turned out to be the president of the National University of Geosciences, that is, Zhang Tianyuan's teacher, hearing this, Zhang Tianyuan felt that this woman was really lucky enough, and she could get her own teacher's personal appraisal, so she would probably get a satisfactory result.

On that day, Dou Xiaoling came to the testing center of the University of Geosciences, and Li Mingguang, president of the National University of Geosciences, was deeply impressed by this bloodstone, "We did test it." "Li Mingguang has been engaged in jewelry appraisal for more than 20 years, and has a diamond membership certificate of the Royal Gemological Society, of course, this is nothing, and the most important thing is that he is the most authoritative gem identification expert in China.

Li Mingguang introduced that to determine whether a stone is bloodstone, not red on the surface of the stone is bloodstone, but to use an instrument to analyze it by infrared spectrum to detect its composition. After the ingredient results came out, a number of appraisers from the appraisal center consulted on the conclusions and finally unanimously determined that this was the genuine bloodstone.

The "blood" in bloodstone is mainly composed of cinnabar, also known as mercury sulfide. The part other than the blood color is called "dizi", and its composition is clay minerals such as Dikaiite. According to the examination, the corresponding parts of the stone submitted for inspection contain these two components, which meets the conditions of bloodstone. (To be continued......)
