As soon as Karen said these words, the vendor opposite was stunned.

He never expected that he would meet an expert here today.

At this time, Chen Rui also turned to look at Karen.

Only then did he remember that Karen was the best at appraising jewelry.

He must also know a lot about various gemstones.

He turned to look at Karen, who was now weighing a rough stone in his hand and looking at the stall owner with a half-smile.

After the stall owner was exposed, he had a rather embarrassed expression on his face.

But after being stared at by Karen like this for a while, he was defeated by the gaze.

A face that was originally red became even redder now.

"The most remarkable feature of the green color of pure emerald is its gentleness."

When Chen Rui heard this, he couldn't help but be a little confused.

Why are gems so gentle?

Until he saw Karen, turning over the ring he was wearing on his hand, revealing the emerald ring inside.

"The color of real emerald should be like this!"

As she spoke, she put the ring surface and the rough stones together.

After such a comparison, even a layman like Chen Rui could see it at a glance.

The surface of this emerald is indeed more colorful, and the green is a lush green.

And because there are inclusions inside the gem, the green color looks like a green cloud.

Looking at the cloud-like halo, Chen Rui finally understood what Karen meant by the gentle green.

Looking at the rough stones, although they are not small in size, in terms of color, they are really much different from the ring surface on Karen’s hand.

He could even see that the green background of two of the rough stones was tinged with yellow and blue.

Doesn’t seem so pure!

This is the so-called expert who knows whether something is there or not as soon as he makes a move.

If Karen hadn't been around today, he would have been deceived by the stall owner.

He looked up at the stall owner, who was scratching his head in embarrassment at the moment.

"Hey! I don't really understand. I also got these rough stones from others at high prices."

"Mad, it seems that I have been deceived. No, I will go to him to settle the score later."

Seeing how embarrassing he was in directing and acting, Chen Rui naturally didn't intend to expose him.

But he turned to look at Karen: "Since these rough stones are not emeralds, then what are they?"

The stall owner also craned his neck and looked at Karen, waiting to see how she would explain.

Karen smiled lightly: "These two pieces are Brazilian tourmalines!"

"You see, their shapes are all columnar rough stones, which is basically the same as emeralds."

"But the only difference between them is the color."

"Generally speaking, the green color of emerald is deeper, and emerald contains more minerals."

"Emeralds are generally not very transparent, but tourmalines are different."

"The green span of tourmaline is very large. Its color starts from light blue and can span to rich green."

"And because there are fewer minerals inside, tourmaline has very high transparency."

"Sometimes, it can even reach the level of high-purity glass."

"Another point is that the hardness of the two is different. The hardness of emerald is 8 degrees on the Mohs scale."

"The hardness of tourmaline is only 7 degrees on the Mohs scale."

"It may seem that the difference is only one degree, but this degree makes the hardness of the two completely different."

"Furthermore, because tourmaline is produced in large quantities, the price is naturally much cheaper than emerald."

Karen gave such an explanation, and the vendor opposite was also convinced.

At this moment, he finally confirmed that the woman in front of him was an expert in gemstones.

If you don’t want to embarrass yourself, it’s best not to use those deceptive methods.

At this time, Chen Rui seemed to be a curious baby.

He pushed two other green rough stones with irregular shapes in front of Karen.

"What about these two pieces?"

These two pieces! Aren’t these the favorite stones of you people in the Dragon Kingdom?

Karen looked at Chen Rui with a smile and said, Chen Rui suddenly realized.

"You mean, these two pieces are jade?"

"That's right, these two pieces are actually raw jade stones..."

"What?"

Hearing Karen's affirmative answer, Chen Rui was confused at that time.

He looked at the two rough stones in his hand. The shape of the two rough stones was not so regular.

But it’s about the size of a thumbnail, and it depends on how rich the color is.

The color of these two stones is even darker than the color of the two tourmalines.

Although he doesn't understand jade, he also knows that if such a rough stone is polished well.

At the very least, it can be made into several rings or earrings.

Just these two rough stones, if they were brought back to China, wouldn't they be sold for 1.8 million?

Although he has never bet on stones before, he also knows how popular jade is in China.

About ten years ago, this thing was even more popular in the country.

Any family with some wealth would not be able to get an jade bracelet or something for their daughter-in-law.

Back then, he and his mother were traveling to a southern province.

I once bought a pair of jade bracelets locally, and they were said to be of some kind of ice.

At that time, it cost my mother more than 80,000 yuan. Fortunately, his family was not short of money at that time.

But it was precisely because of that experience that he still has a vivid memory of this gemstone.

"But isn't this kind of gemstone produced in Myanmar? Why did it come so far to be sold here?"

"And this kind of gem was very expensive in our Dragon Kingdom before."

Chen Rui looked at the stone in his hand in disbelief and said.

Karen smiled and gave his explanation.

"That was before, how can it be so expensive now?"

"In the past, it was really only Myanmar that produced this stuff, so it was very expensive."

"But in recent years, jade mines have also been discovered in Guatemala, Central America."

"So now the jade market prices in Dragon Kingdom have collapsed..."

Karen is indeed an expert in the field of jewelry. She has a thorough understanding of the general situation and market conditions of various gemstones.

Chen Rui was given a science popularization on the spot, and Chen Rui heard that the domestic jade market had collapsed.

He even slapped his thigh happily!

"Okay, it collapsed well, it should have collapsed a long time ago."

The reason why he is so happy is naturally because he hates those profiteers who deal in jade.

Just talk about the pair of jade bracelets his mother bought. When he returned to China a few years ago, he heard his mother nagging about this.

At that time, my mother said that her friends said this jade bracelet was not worth it.

The price is exaggeratedly high, just like a pig-killing plate hyped by merchants.
