"Speak serious!"

Chen Zhengqian put away the hippie smiley expression just now and said seriously: "I'm short of money recently. I want to take some collections. I wonder if you are interested?"

"What?" Zhou Xinxin asked curiously when he heard what he said.

"Black gem." Chen Zhengqian replied.

After hearing this, Zhou Xinxin frowned: "Black gem? If you are talking about obsidian or black tourmaline, forget it, it would be fine if it was black jade, but the price might not be much higher."

The common black gems on the market are just these types, and there are also the so-called black agate. In fact, they are changed by heating and cannot be considered pure and natural black gems.

But these black gems are not necessarily very expensive.

Chen Zhengqian was stunned. This was not much the same as he expected.

In her opinion, black gems should not be very rare. The price is higher than other gems, right? Why is it not as good as ordinary gems?

You should know that in your warehouse, in addition to the black gem given by the money tree, there are several larger black gems. If these black gems are not valuable, it will be a bad thing.

Chen Zhengqian quickly said, "You wait first, I'll check the information first."

I immediately hung up the phone and started to find information online.

Zhou Xinxin looked at the hung-up call and was speechless.

After checking the information, Chen Zhengqian realized that he had really made a mistake.

There are many or few information about black gems online. The black gems mentioned above cover many types, and in addition to the ones mentioned by Zhou Xinxin, there are others.

But compared with the black gems in his hand, just looking at the appearance, you know that it is not the same type.

Then is this black gem?

Looking at the black gem in his hand that was as big as a thumb and exuded a charming black luster, Chen Zhengqian hesitated.

He called Zhou Xinxin again: "Hey, Liujin, my black gem may not be much the same as you imagined. I can't explain clearly where the specific location is different. I will go to your company later, and you can help me find someone, or help me with an appraisal."

"Okay, just do whatever you like." Zhou Xinxin shrugged, not saying that.

Anyway, it's just an appraisal, not a hassle.

Chen Zhengqian hung up the phone and went to Dafu Jewelry Company to find Zhou Xinxin.

When he arrived at Zhou Xinxin's office, Chen Zhengqian handed over the small box containing the black gem: "Here, the gem is here, please help me see."

Zhou Xinxin took the box and opened it. He immediately said "Huh". He saw a shiny black gem lying inside the box. You can tell at a glance that it is an extraordinary black gem, and it is unexpectedly large.

Although it is a source drill, its purity is not bad at all compared to that after cutting.

Looking at this black gem, there is always an indescribable feeling. Although it is pure black, it makes people feel indifferent and peaceful.

Strange thing!

Chen Zhengqian asked: "Is there any problem?"

Zhou Xinxin frowned slightly: "It's weird! Where did you get this black gem?"

He is in the jewelry business, but he has never seen a black gem of this texture. Among other external factors, just from the appearance and texture, this can be regarded as a top gem.

I don’t know where this guy got it, but I feel that all the treasures in the world are on him.

It's really jealous.

Chen Zhengqian shrugged: "Don't ask about this, please find someone to help me."

He really didn't know how to say the origin of the black gem, so he might as well hide it. Anyway, Kim would definitely help solve the source of the gem on Saturday.

Since he didn't want to say more, Zhou Xinxin didn't ask too much, so he called: "Let Zhang Song come to my office."

Soon a gray-haired uncle walked into Zhou Xinxin's office.

Zhou Xinxin hurriedly greeted him: "Master Zhang, please help me see the material of this gem."

Zhang Song didn't say much, nodded, and began to pick up the black gem to study it carefully.

Chen Zhengqian doesn’t understand jewelry appraisal either. Although the school has a jewelry school and also has an appraisal major, he has never studied it and feels very tall and proud.

Now, the same is true for Zhang Song's actions.

As a senior appraiser of Dafu Jewelry, Zhang Song naturally had a trick. He did not have diamonds or took on porcelain work, which was the most correct description.

After a long time, Zhang Song put down the box and said to Chen Zhengqian and Zhou Xinxin: "This gem does not look like black agate or black jadeite, nor does it look like obsidian or black tourmaline in terms of transparency or luster.

I personally think it's more like Thai black gems.

It’s just one thing that is very doubtful. Although the quality of Thai black gemstones is also very good, I have never heard of such extremely high quality.”

When he said this, Zhang Song had a hesitant look on his face, and then looked at Chen Zhengqian and Zhou Xinxin.

Zhou Xinxin shook his head without revealing his mark.

Zhang Song immediately understood.

Facing Chen Zhengqian's searching gaze, Zhang Song looked at Zhou Xinxin again, and saw him nodding, and continued: "Thai black gemstones also belong to sapphires, and the composition is alumina.

Because it is buried deep underground, it is basically at the bottom of the mineral and the difficulty of mining is far better than that of rubies and sapphires, so the circulation on the market is small and mysterious and rare.

It is said that most of the black gems in Thailand are collected by the Thai royal family. Even ordinary Thai people rarely hold black gems. What most people wear in their hands are obsidian or coal essence.”

Chen Zhengqian frowned: "Then my black gem should be a Thai black gem?"

“It should be.”

Zhang Song nodded and said, "Black gems are actually easy to identify. The biggest difference between them and other gems is their hardness. The wear resistance of Thai black gems is something that other gems such as black agate obsidian cannot have.

This is also the reason why I judged that this black gem is a Thai black gem, because its hardness is much higher than other gems.”

Chen Zhengqian nodded and asked his most concerned question: "Master Zhang, can you estimate how much this black gem can be worth?"

Zhang Song hesitated, looked at Zhou Xinxin again, and found that he had no expression on his face, so he hesitated and said: "Actually, the specific value is hard to say, but Mr. Chen, you can rest assured that the quality of this gem will not be much lower.

On the contrary, because of the rarity of black gems themselves and the meaning of mystery, people believe that black gems can ward off evil spirits, and their pursuit of black gems is no less than any other gem.

So once such top-quality black gems appear on the market, especially in auctions, it will surely attract a lot of attention and be sold at high prices."

Chen Zhengqian nodded: "I probably understand." It's fine since it's valuable.

Zhang Song smiled and continued: "If Mr. Chen agrees, our Dafu Jewelry Company can do a detailed appraisal for you and provide the corresponding appraisal certificate from the National Jewelry and Jade Quality Supervision and Inspection Center."

Chen Zhengqian glanced at Zhou Xinxin and saw him nodding, but he had no objection: "Okay, I'll bother you."

Zhang Song smiled and said, "No trouble, no trouble. If it's okay, I'll go out first."

Chen Zhengqian quickly stopped him: "Master Zhang, don't worry, there is another thing to bother you."

When Zhang Song heard this, he stopped immediately.

Even Zhou Xinxin looked at Chen Zhengqian in surprise to see if he had any problems.

"Didn't I auction a pearl from you last time? There is another one this time. Although it is not as big as last time, it is almost the same." Chen Zhengqian said to Zhou Xinxin with a smile, and took out a small box from his pocket again.

Upon hearing this, Zhou Xinxin stood up immediately.

Zhang Song was also looking forward to it.
