My system is not decent

Chapter 514 Canglong Godson (for Subscription)

Chalcedony is a mineral, also known as "chalcedony", which is actually a kind of quartz, which is a variant of quartz.

To be clear, it is actually silicon dioxide, um, the same chemical name as sand.

Chalcedony is the same mineral as agate, but there are differences.

A notable feature of chalcedony is that it is as transparent as ice. Good chalcedony can be as transparent as jadeite glass, which is the biggest difference between chalcedony and agate.

The aphanitic quartz with banded structure is agate, and the aphanitic quartz with no banded structure and uniform color is chalcedony.

Of course, as long as chalcedony is natural and relatively beautiful, it has certain value.

For example, carnelian, chrysoprase, etc., as long as they are beautiful, they are generally valuable.

But there are more chalcedony, which are not very valuable, and are very beautiful. When you encounter this kind of thing, you have to pay attention.

A small number of chalcedony varieties have iridescent effect and cat's eye effect. This kind of chalcedony is naturally beautiful and worth some money.

In order to seek huge profits, some unscrupulous businessmen artificially improve the color of chalcedony containing iron factors through heat treatment.

Although there is no chemical addition, it is not a product of natural color after all.

This kind of thing is easy to distinguish as long as you pay close attention to it.

Heat-treated products, because the internal structure is changed, so most of the colors presented are brighter and brighter, but compared with natural products, the foundation is not transparent enough.

In contrast, natural products are darker in color.

"Young man, help me to see, this is white chalcedony!"

"And me, this is blue chalcedony!"

"Mine is blood chalcedony!"

It was finally their turn, a group of women, and they were clearly all excited.

But Chen Wenzhe couldn't get excited. These beautiful chalcedony just fell into their hands casually?

The chalcedony in their hands looks very beautiful, and this grade of jade was also very popular in ancient times.

Just talk about carnelian, which is a translucent chalcedony with fine texture, crystal clear, pure and thick color, and high hardness.

The carnelian is lightly tapped, and the sound is clear and melodious. Compared with the expensive jadeite, carnelian is a natural gemstone with a low price, but this thing is not a Chinese cabbage.

Natural carnelian can be found in almost every great civilization.

From the civilization of Ur, the capital of Mesopotamia before biblical times.

In the era of Napoleon, Napoleon brought back a huge octagonal carnelian when he triumphed in Egypt.

Then to the Tibetan Buddhist civilization, carnelian has been preserved for its excellent qualities in medicine, spirit and creation.

Carnelian is a gemstone with strong religious color. The stone of longevity of the Egyptian goddess Isis in her later years is carnelian.

The ancient Greeks and Romans used carnelian for intaglio (intaglio) signet rings, and the ancient Romans also symbolically associated dark carnelian with men and light carnelian with women.

The jade seal of Muhammad of the Arab Empire is a carved carnelian with a silver ring.

Such a thing, no matter how much the output is, it is impossible to buy it casually for dozens of dollars, at most hundreds of dollars, right?
"I also heard that chalcedony is cheap, but it is really beautiful. Please help me to see if this is chalcedony? As long as it is, no matter how large the output is, it will only affect the price. It is beautiful, but it is real. .”

Seeing the triumphant young woman in front of him holding up the blood chalcedony in her hand, Chen Wenzhe was speechless.

"Your carnelian should have been heat-treated."

"what?"

"There are many colors of chalcedony, which can be divided into red chalcedony, blue chalcedony, white chalcedony, chrysoprase and so on according to the color."

"But don't think that they are the green/yellow we imagine, because there are many colors in nature."

"The color is mainly due to the elements in the stone, the color shown, so there are very few pure colors in nature."

"We all know that rare things are expensive, so there are a lot of fakes that are rare and expensive in the market."

"The manufacturing cost of fake chalcedony is low and the color is bright, but one thing everyone must know is that fake chalcedony is chemically treated at high temperature. Frequent wearing of this kind of chalcedony containing chemical agents will reduce our body's immunity and increase cancer risk."

I didn't want to say more, after all, it would cut off many people's money.

However, things that have been processed are harmful. If such things are not clearly explained, Chen Wenzhe still feels uneasy.

It is actually very simple to identify the true and false of chalcedony. First of all, look at the overall fineness. The overall fineness of fake chalcedony bracelets is single and uniform, with almost no impurities.

Then look at the color of a single piece, the color of a single piece of false chalcedony is very uniform, there is almost no color depth, and there are very few impurities.

The last thing is to look at the price. Fake products are often beautiful and cheap. Of course, this is not absolute. The most effective way is to look at the color.

In terms of color, it is not recommended to choose blue chalcedony and purple chalcedony, because these two types are basically dyed in the market.

If you really want to buy it and really like it, then it is best to choose white ice, or yellow-red chalcedony, which is more natural.

Also, the red color of carnelian is actually [orange], so it is not recommended to buy if it is too red or deep red.

After finishing speaking, Chen Wenzhe looked at the young woman's blood chalcedony, needless to say, it was dark red.

"You say I'm a fake?"

"As I said before, some people use chemical heat treatment to make chalcedony more beautiful."

"It's still fake!"

"If it's fake, it's fake. Look at me, my chrysoprase, I heard it's rare."

At this time, someone behind couldn't help it anymore, she thought that hers must be good.

Taking a closer look, Chen Wenzhe found that this piece was not even chalcedony, but a piece of green glass.

Although chalcedony is the most common jade variety in nature, it is also one of the oldest jade varieties in human history.

The color of chalcedony is rich and colorful, and some varieties have peculiar patterns and beautiful patterns, which are amazing.

Among the color types, blue and green chalcedony are rarely produced, and these two are also more valuable for collection.

Unfortunately, those unscrupulous merchants who cheat in the market, how could they not know the value of blue and green chalcedony?
Therefore, buying expensive things in the market is not necessarily a good thing, but buying cheap things is definitely not a good thing.

After exhausting his tongue, he finally sent a group of women away, and this time it was an old man who came over.

The things he brought were finally able to take a look at them.

This is a white jade ruyi. It looks like the carving is not bad, but it feels a bit stiff.

"Canglong teach son?"

Looking at this piece of jade Ruyi from a distance, it felt okay, but when he took it in his hand, Chen Wenzhe found that it was made by modern machinery, and the carving was relatively random, and even the carving was wrong.

You should know from the name that Canglong Godson must have carved two dragons.

One big and one small, one old dragon, one young dragon.

Ruyi's two ends are just such two dragons.
