Looking at the few pieces of ancient jade, Zhao Tianming pursed his lips even more.

"You can't tell that these ancient jades are fakes, especially that brand, which is simply worthless. Zhao Tianming said again.

It can be said that except for those nuclear eagles, everything else is a bit fake.

"Then I still earned it. I don't know much about ancient jade, and it's understandable that I can make an eye. ”

Can you comfort yourself like this? Zhao Tianming is really insightful.

But the previous sentence is really not wrong, just those nuclear carvings are worth more than two million. And this large pile of things cost Ye Qiushuang less than 50,000 yuan, no matter how you look at it, it is a big profit.

Compared with before, Ye Qiushuang felt that he had been calculated recently.

"Everything else is fine, at least it's real jade, it's just old. But that jade plaque, the jade is all fake. Zhao Tianming said to her.

Jade can be divided into nephrite and jadeite, there are many kinds of nephrite, such as the famous Hetian jade, jadeite is usually jadeite.

If we look at the chemical composition, nephrite is a silicate containing calcium, magnesium and iron, while jadeite is a silicate containing sodium and aluminum.

There is actually a very simple way to distinguish real jade from fake jade.

A drop of water is dropped on the jade, and if it is in the shape of a dewdrop, it is a real jade that does not disperse for a long time.

And people who feel good can touch it with their hands, if it is real jade, they have a feeling of cold lubrication when touched by their hands. The natural stones rub against each other, feel slippery, and the friction will not leave scratches. Synthetic products rub against each other, feel astringent, and will produce scratches at the friction after friction. This reason is mainly due to two different hardnesses.

Some fake jade is an artificial jade with jade powder mixed with chemical high-strength coagulant that is pressurized at high temperature to form a color and a certain imitation of special jade.

This kind of artificial jade is inexpensive, but some jewelry stores will use these things as shoddy. Don't think that some jewelry stores and some jade still have verification certificates, but they are actually fakes.

Artificial imitation material, no matter how realistic, to give people the vision is always a single color, from the color and luster, the color and permeability of pure natural stone is not only good and poor, and there is also a certain irregularity, no matter how good the natural jade, there is no cotton-like substance.

If you encounter the kind of jade that is completely free of impurities and cannot see the cotton through the light, you have to be very careful.

Of course, Taobao armies like them often carry gadgets like magnifying glasses with them.

Using a magnifying glass, as long as it is a natural stone, no matter what grade it is, there will never be a small bubble in the jade, which is determined by the chemical and physical roots of the natural jade.

In the past, Zhao Tianming couldn't tell the difference, it was really between fake jade and real jade, and outsiders couldn't see much difference at all.

Those fake jades, worn on the body, are still harmful to the body.

Because some fake jade has undergone strong acid precipitation, the natural crystalline structure of the stone and the original chemical formula have changed. Visually, there is no longer the oily feeling of natural stone. All that's left is the feeling of light and brightness. Losing the unique warm color of jade, the texture becomes bright and regular.

And those strong acidic potions often remain in the jade, and after wearing them for a long time, they will enter the human skin and cause certain damage to the human body.

Zhao Tianming picked up another piece of jade and said: "The stone of this handicraft is natural jade, but the processing process is non-hand-carved, purely from the aesthetic point of view, it is very good, and the precision is not achieved by hand." ”

But the value of the collection will be tens or hundreds of times different from that of real handicraft. The process cost of the mechanism is relatively low, and the market price is not high, because of mass processing, there is no other cost except for the cost of basic raw stone and mechanical cost, and there is no unique value and humanized personality value, which is nothing more than the value of an ordinary commodity.

"I think it's better for you not to touch Gu Yu in the future. Zhao Tianming reminded.

This girl's understanding of Gu Yu is half a bucket of water, and a quarter of a bucket of water is not enough! This kind of Taoism is the easiest to suffer.

Jade is also the most popular handicraft in the market and belongs to the most popular handicrafts, so there are many fakes.

On the street, we can often see that such a big jade plate, jade carving, jade plate finger, jade handpiece, jade ornament, dare to call Hetian jade only sell for dozens of yuan, dare to call Hetian Ziyu only sell for a few hundred yuan, dare to call mutton fat jade only sell for a few thousand yuan, which is incredible.

In addition, what are the ancestral heirlooms, the fake ancient jade dug up in the ground, the ones sold by friends, and what are the patterns, and what is even more odious is that there are fake Hetian jade made of synthetic materials, so that you can't guard against it, in short, there are all kinds of things, varied, dazzling, and there are really a lot of fame.

He pointed to one of them: "This one piece is still worth a little money, and the rest can be thrown away." ”

It was a green ox carved from a piece of green jade, the jade quality was medium, and it was artificially carved, the only thing that was wrong was that it was artificially old.

Green jade is the largest component of nephrite jade, its material composition is the same or similar to that of white jade, and the origin is the same as that of white jade, which is formed by contact metamorphism, and only shows differences due to the trace element iron.

It is precisely because of the large number of green jade that its value is usually not high, and there are few high-end goods.

From Shang, Zhou to the Warring States period, green jade has always been the largest number of Hetian jade. Until the Han Dynasty, white jade began to be valued, but green jade was not overwhelmed by the trend, and always paralleled white jade in the historical stage.

Green jade from light cyan to dark cyan, there are many types of colors, ancient books record the worm green, snot green, crab shell green, leaf green and so on. In modern times, there are different shades of color, and there are also light blue, dark blue, blue blue, gray blue, dark gray blue and so on. Khotanese jade has the most green jade, and large pieces are common. In recent years, there is a kind of emerald jade, which is pale green.

Now, the piece they saw was the emerald jade.

The emerald jade in Kunlun jade refers to the jade with emerald green bands distributed on the base of Kunlun jade. It has the solemnity of general white jade, and the freshness of emerald green, and its green is attached to the white background, like the buds of spring branches, giving people a feeling of vitality and vigor.

People who use this kind of jade as old are also a bit stupid.

If it is a new jade, it has not been tampered with, maybe it is worth a little more. After being old, the color is not so good-looking, and the value is affected to a certain extent.

"Forget it, no matter what. I heard that the auction was going to start soon, so I rushed here. By the way, I heard that you joined Jinhe Auction House?" Ye Qiushuang said.

"It's hard to be a consultant. ”

Ye Qiushuang looked at Zhao Tianming's dragging appearance, and was a little unhappy.
