“What a beautiful diamond!”

In the room, Mother Zhou was wearing a pair of glasses and holding a magnifying glass to carefully examine the red diamond in her hand. After a long time, she finally said with a smile on her face.【】

She was a famous jewelry appraiser in Qingjiang City, and she was very satisfied with the red diamond brought by Zhao Kongming. Although it was not inspected by high-end electronic equipment, for Zhou's mother, a magnifying glass was enough for her to discover this red diamond.

The beauty of a diamond.

"Kong Ming, my aunt is happy to accept this red diamond!" Zhou's mother was very satisfied with Zhao Kongming and nodded to him with a smile.

"Auntie, don't say that. In fact, I have long wanted to give this red diamond to my aunt, because I think only my aunt is worthy of this South African red diamond!"

Being praised by Zhou's mother immediately put a smile on Zhao Kongming's face. He knew that the moment Zhou's mother accepted the diamond, he would be one step closer to achieving his goal.

Thinking of this, Zhao Kongming didn't forget to look back at Nie Fan. A look of contempt flashed deep in his eyes, and the corners of his mouth turned up and he said to Nie Fan: "How is it? Brother Nie, my red diamond is not bad, right? In fact, you should

Do your homework early, after all, almost everyone in Qingjiang City knows that my aunt likes jewelry."

After listening to Zhao Kongming's sarcastic words, Nie Fan showed no signs of embarrassment or anger on his face. Instead, he smiled with a playful look on his face.

"Brother Zhao, what you said is wrong. In my opinion, although your red diamond looks perfect, it is not a natural red diamond, but a synthetic chemical red diamond!"

What!

Nie Fan's words made Zhao Kongming look startled, and then he became furious: "Nie! If you don't know, don't talk nonsense! I spent a lot of money to buy this red diamond from South Africa. It's proper.

Natural diamonds, why do you say that my red diamond is a man-made chemical red diamond!"

Looking at Nie Fan's plain face, Zhao Kongming was out of breath. You must know that there is a huge difference between chemical red diamonds and natural red diamonds. The so-called chemical red diamonds are artificially synthesized. As long as you have the raw materials and

Using molecular recombination technology, such diamonds can be mass-produced. In this way, the luxury and nobility that diamonds should have are lost. Nie Fan kept saying that the diamond he bought at a high price was a chemical red diamond, which was certainly enough to make Zhao Kongming angry.

.

"Boy, you'd better think clearly before you speak!"

Zhao Kongming was angry. If Zhou's mother hadn't been there, he might have punched Nie Fan.

However, Nie Fan did not take Zhao Kongming's words to heart at all. Instead, he smiled slightly, shrugged and said, "Brother Zhao, no matter how hard you try to hide it, you are just deceiving yourself."

"What the hell..."

Seeing that Nie Fan dared to speak nonsense, Zhao Kongming couldn't help it. Even if Zhou's mother was still there, he would fight to the death with Nie Fan.

However, Zhou's mother sternly stopped the two of them. At the same time, she looked at Nie Fan with a puzzled expression and asked, "Xiaofan, what's going on? Why do you say this is a chemical red diamond?"

Zhou's mother is a jewelry appraiser herself. Although she did not have high-precision inspection instruments at hand when she appraised the red diamond, for Zhou's mother, more than ten years of experience in the industry was not in vain. With her eyesight, even if she does not have high-precision inspection equipment,

Precise inspection equipment and years of experience can identify a jewelry diamond with more than 80% certainty.

After Zhou's mother's self-examination, this red diamond was indeed genuine. How did Nie Fan come to say that it was a chemical red diamond?

"Humph! Auntie! Don't listen to his nonsense!"

Zhao Kongming suppressed his anger, snorted coldly, and said angrily: "In my opinion, this kid is probably angry because he deliberately called my red diamond a chemical red diamond. He is jealous of me.

Miles!"

Mother Zhou's face darkened, and she was very reluctant to treat Nie Fan like this, but how could Nie Fan be so sure that this was a chemical red diamond?

"Xiaofan, please say a few words!"

Although Zhou's mother didn't want to admit that Nie Fan was a jealous person, she also didn't want to disgrace herself. After all, this red diamond had been carefully inspected by her. In her opinion, it was indeed a genuine natural red diamond.

Drill.

After hearing what Zhou's mother said, Nie Fan smiled and nodded, then picked up the so-called natural red diamond, pointed at it and began to speak slowly: "There are many differences between natural diamonds and artificial diamonds, but these differences are often not easy to distinguish.

People can see it mainly from the hardness, chemical composition, thermal reaction and optical properties."

After saying that, Nie Fan smiled and said to Zhou's mother: "Say this in front of my aunt, it may feel a bit like playing a knife in front of my father's door, but aunt, I would like to ask, what is the power of the magnifying glass you just used?"

Mother Zhou was stunned for a moment, then thought about it and said, "If I remember correctly, it should be an eight-power lens."

"That's right!"

Nie Fan snapped his fingers and then said: "One way to distinguish natural diamonds from artificial diamonds is to use a ten-fold mirror to observe the texture of the diamond. If it is a natural diamond, the ridges will be very sharp and the polishing will be smoother.

This would not be the case if it were a man-made diamond. The edges would be sharp and the polishing would be extremely poor!”

As Nie Fan spoke, he handed the red diamond to Zhou's mother and said with a smile: "If Auntie doesn't believe it, you can look at it with a 10x mirror!"

Zhou's mother was doubtful, but Nie Fan's words made sense, so she still asked her to find the ten-fold mirror again and observe it carefully.

It didn't matter. Mother Zhou immediately exclaimed: "Sure enough!"

It turned out that Mother Zhou could not clearly see the ridges inside the diamond when she used the 8x lens. Now, after using the 10x lens, she immediately saw the blurry ridges inside. This is one of the main characteristics of artificial diamonds.

"No...this is impossible!"

Zhao Kongming obviously did not expect that things would develop like this. He thought that the diamond he dedicated to Zhou's mother was very rare and would definitely win her favor, but he did not expect that Nie Fan would see that it was an artificial diamond.

Zhao Kongming couldn't believe it and couldn't help shouting: "I spent hundreds of thousands on this diamond, how could it be fake!"

Hearing this, Nie Fan smiled coldly and said, "Has Brother Zhao never been deceived before?"

Zhao Kongming was startled at first, and then said harshly: "Nie, don't talk nonsense here. Maybe the color of this diamond is not good, which is why there are the ridges and bumps you mentioned. Apart from that, you

Is there any other evidence that can be produced to prove the authenticity of this diamond?”

"Of course!"

Nie Fan seemed to have expected that Zhao Kongming would say this. He immediately smiled, picked up the diamond, and said to Zhao Kongming: "Real diamonds are composed of carbon, with a molar hardness of 10, which is the hardest thing in the world. So I think
