Ye Mei and Zhu Zi stopped at a stall full of similar crystal ornaments.

Teacher Ren, Xu Hong and others continued to move forward, they were not very interested in these things, only Hu Yang and Andy followed.

"This is a crystal, right?" Andy felt like a crystal, and seeing that it was not expensive, he was even more determined that it was a crystal.

The stall owner is a man with long hair, and from a distance, some people may think it is a woman. This person is gay and gay, and he feels a little pseudo-girly.

He was not enthusiastic about Ye Mei and Zhu Zi, who squatted down to choose jewelry, but "smiled" and talked to Andy: "Hehe, handsome guy, then you are mistaken!"

A man, with long hair, didn't count, burst out of his mouth the word "hee-hee", and the audience in the live broadcast room felt goosebumps.

"Damn! this guy is definitely a pseudo-girl, disgusting to me. ”

"A hee hee made my scalp tingle. ”

"I, a woman, was speechless when I heard it. What's wrong with the men now?"

"Ladies, isn't this the little fresh meat you want? ”

"That's it, men are like this, isn't it still from you women? Usually those little fresh meats, when you laugh, you have to cover your mouth, and in the eyes of you women, they become cute, and you don't know that we are losing our appetite. ”

......

Andy couldn't help but take a step back and looked at the stall owner vigilantly.

The stall owner brushed his hair, pulled it behind his ear, and said, "Look, doesn't it look like a diamond?"

Hu Yang didn't give him a chance to sell Guanzi, and directly made it public: "This is Haoshi, and it is also artificially synthesized." Crystals are not like this, I have told you before, natural crystals are clear and transparent, often containing star-shaped, cloud-like or flocculent gas-liquid inclusions, and micro-cracks are often visible. This piece is completely devoid of these characteristics. ”

The stall owner was stunned, obviously not expecting someone to tell the true identity of these things at once.

Ye Mei asked: "Brother Hu, what is Haoshi? Is it also a gem? This synthetic one is definitely not worth much!"

Zircon is a silicate mineral, which is the main ore for refining zirconium metal, and is widely found in acid igneous rocks, but also in metamorphic rocks and other sediments, Populus explained.

Zircon is chemically stable, so gem-quality zircon can also be found in the gravel of rivers. There are many kinds of it, and different zircons will have different colors, such as black, white, orange, brown, green, or colorless transparent, and so on. Cut gem-quality zircon is much like a diamond.

It is precisely in this way that the stall owner asked just now: is it quite like a diamond?

Moreover, because zircon and diamond are very similar in appearance, but the price of zircon and diamond is far from the same, some unscrupulous merchants use zircon to pass off as diamond, deceive consumers, and make huge profits.

Before the advent of various man-made diamonds, zircon was the best substitute for diamonds. At present, zircon has become a leader in low-to-mid grade gemstones.

"Isn't it a hyacinth stone?" asked the ziko, the expression on her face a little cute.

Hu Yang smiled: "Well, in your Japan, it is called hyacinth stone." ”

The stall owner scolded Yemei: "Natural Haoshi, you don't dare to wear it." ”

Ye Mei and the others were puzzled when they heard this, but everyone did not seek answers from the stall owner, but looked at Populus Hu. Obviously, everyone is not very interested in this gay angry man.

"Then it depends on what color, you give me blue, see if I dare to wear it. ”

There are very few natural blue zircons, most of the blue zircon is obtained after heating with zircon of other colors, it has obvious polychromacy, showing blue and green, and the best one is sky blue.

"Why?, can't you wear other colors?" Andy was a little confused.

Hu Yang told them: "Natural Haoshi generally has radioactive elements, especially green ones, and is generally not made into jewelry to wear." Low-type zircons are also unacceptable, low-type zircons are zircons that crystalline change to amorphous due to radioactivity, which are equally radioactive.

Blue natural Haoshi, the radioactive elements are very low, the impact is not great, and because it is rare, it is precious. ”

This time, everyone was surprised that there were radioactive elements, no wonder the stall owner said that you didn't dare to wear it. Indeed, humans are shy away from radioactive elements, and the consequences of that thing are too serious to touch.

"Is there such a thing as a low type?" Ye Mei asked curiously.

"Yes, and the low-grade Haoshi can also be heated to a certain extent and transformed into colorless, or blue, high-type Haoshi. ”

As you know, many things can be denatured by heat treatment, and the same is true for zircon. If the low-grade zircon is heated to a certain extent, it will become a colorless transparent crystal.

For example, the zircon of Sri Lanka is mostly green and low-type, and after heat treatment, the color is significantly lightened, becoming a high-grade zircon gemstone. There are also red and brown zircons produced in Hainan Province, China, which can be turned colorless after heat treatment.

In fact, many Haoshi in China are now synthesized.

Wuzhou, Guangxi Province is the world's largest synthetic base of artificial haoshi, accounting for more than 80% of the total domestic zirconia market and more than 40% of the world's total cubic zirconia market.

It is precisely because of this that Wuzhou is also known as the "capital of artificial gemstones".

The main thing is to melt the zirconia powder mixed with stabilizer, and then slowly crystallize to form cubic zirconia crystals, through its cutting, polishing, processing to form a variety of artificial zircon products, used in jewelry, handicrafts, clocks, clothing and other inlaid artificial zircon products.

It is said that there are more than 100,000 people engaged in this industry in Wuzhou, which shows how large the scale is.

"Then if someone uses this thing as a diamond, how can they tell the difference?" Ye Mei asked again.

"It's easy! You can breathe at it, and if you want to do it, it spreads very quickly. The surface of a diamond is so smooth that it does not retain water and condensation. ”

The stall owner was a little dumbfounded, this man seemed to know everything about Haoshi!

Knowing that it was synthesized, the interest of the two girls suddenly dispersed a lot, but since they had seen it all, they also picked one or two pieces for face.

After completing the transaction, Hu Yang took them and quickly caught up with Teacher Ren and them.

Hu Yang saw that Xu Hong was arguing with a stall owner, and it seemed that there was a conflict, and in the middle of them was a porcelain statue.

"Hey, why are you like this? Negotiate a good price, and don't want to make a deal of it? "The stall owner is a bald head, with tattoos on his neck and a fleshy face, which is not easy to mess with.

He spoke a little loudly, deliberately drawing everyone's attention.
