"Fie'er, you are from jewelry identification. I think you should tell this rich young man the origin of Tanzanite?"

Hao Huai just discovered that Tang Feier was also curious when he saw the ring face, so he understood that Tang Feier did not realize that it was a Tanzanite stone, but he knew that Tang Feier had definitely heard of it, so he asked her to introduce it after explaining the name of the gem.

"So this is the legendary Tanzanite."

Tang Feier got up and picked up the ring, and then told the history of Tanzanite. I think the beauty tells her that she does have a different flavor than the rough man Hao Huai, which attracted many classmates to watch. People also know the competition and "reward" of the two teams of couples, and of course their interest is even stronger.

After listening to Tang Feier's story, Sun Yuming felt a little nervous, but the surrounding classmates were full of onlookers, which made him dismiss his plan to withdraw.

"Okay, I, Sun Domain Name, lost this game, but if you can't tell me that pendant, it can only be considered as normal."

Hao Huai spread his hands open at this time. The pendant in his hand was a light yellow gem the size of a little finger cover. A white mark in the middle of the gem was very obvious, just like a cat's eyes.

"Cat's Eye?"

Although Hao Huai is not particularly proficient in gems, he has heard of cat eye stones for a long time, and has also consulted relevant information when he was using gemstone knowledge before.

In ancient Egypt, there was a mysterious legend circulating in the cat's eye stone ring on the hand of a pharaoh. When the cat's eyes were opened, it means that the gods were angry and needed to take human life. They came to worship the gods to calm down and soothe the power of the gods.

In addition, it is said that when the minister entered the court, the Pharaoh decided the minister's position or life by blinking the cat's eye stone in his hand. Until now, there are still many backward areas in Egypt, using cat's eye stone to worship the main gods.

There are also legends about cat eyes in our country. The reason why Empress Dowager Cixi of the Qing Dynasty was able to take charge of the government was due to the divine power of a cat eyes stone weighing about twenty carats. It is said that every night, she placed the cat eyes stone under a pillow to sleep, and the cat eyes fairy would appear in her dreams and instruct her actions the next day.

According to legend, the death of Concubine Zhen was the will of the Cat-eyed God. Even the rise of the Boxer Rebellion in the future was also because of the fact that the Cat-eyed God instructed Cixi to let him become a big shot in his dream, leading to the chaos that would be uncontrollable in the future.

In Southeast Asia, cat's eye is often regarded as a symbol of good luck. People believe that it will protect its owner's health and longevity and avoid poverty. Cat's eye is often called a noble gem. Together with the transformed stone, it is one of the five precious and high-end gems in the world.

Cat eye is mainly produced in gas-forming hydrothermal deposits and pegmatite veins. The most famous cat eye producing areas in the world are Tranabra and Gor in southwestern Sri Lanka. Cat eye is also found in Brazil and Russia and other countries, but it is very rare. Cat eye is mainly produced in gas-forming hydrothermal deposits and pegmatite veins. The most famous cat eye producing areas in the world are Tranabra and Gor in southwestern Sri Lanka. Cat eye is also found in Brazil and Russia and other countries, but it is very rare.

Common colors are golden, yellow-green, gray-green, brown, brown-yellow, etc. They are mainly produced in Sri Lanka, Brazil and other places. Sri Lankan cat eyes have always been famous all over the world.

There is also a very ancient legend about the golden green cat eyes - an old man raising a cat lived in the White Beard Mountains of ancient Sri Lanka. The old man relied on his cat for his life. After the cat died, the old man was very sad.

Later, the cat asked the old man to dream. When the old man opened the cat's grave, he found that the cat's eyes were as hard as beads, and there was a bright strip in the middle, which was very beautiful. So the old man buried one cat's eye into the White Hu Mountain and ate the other one. The old man became an immortal because of this. Later, the mountain was famous for producing cat's eye gems.

Cat eyes are considered a symbol of good luck, protecting their owners from poverty and becoming rich, and healthy and longevity. Cat eyes are noble gems. Generally, high-quality cat eyes weighing a few carats are very precious, and their price is comparable to high-quality emeralds and rubies.

"Cat's Eye" is also called "Cat's Eye", "Cat's Eye", "Cat's Eye", also known as Oriental Cat's Eye. People are used to call "Golden Emerald" with "Cat's Eye effect" "Cat's Eye".

"Cat's eye" and cat's eye effect are two completely different concepts, because there are many gems with cat's eye effect, and according to statistics, there may be as many as thirty types.

Therefore, "cat's eye" is not the name of a gem, but an optical phenomenon presented on some gemstones. When a gem ground into a hemispherical shape is irradiated with strong light, a thin and bright reflection will appear on the surface, called "cat's eye flash" or "cat's eye lively light". Then it is named according to what the gem is. If the gem is quartz, it is called "quartz cat's eye".

In fact, there is only one kind of gem that has a cat's eye effect called "cat's eye", that is, "golden and green cat's eye", and only it is the "cat's eye" in the traditional sense.

There are a large number of small, dense, parallel-arranged filamentous rutile mineral enclosures inside the emerald mineral. Due to the large difference in refractive index between emerald and rutile, the incident light is reflected through the rutile enclosure and concentrated into a light to form a cat's eye. When the emerald is more opaque and the denser the rutile filamentous body, the more obvious the cat's eye effect is.

When a cat's eye gem is illuminated with a concentrating flashlight, at a certain angle, the cat's eye appears yellow toward half of the light, while the other half is milky white. If two concentrating flashlights are illuminated from two directions and turn the gem back and forth with the direction of the filamentous enclosure as the axis, you can see that the cat's eyeliner opens and closes for a while.

The main identification feature of cat eye is that you can see clear brown-yellow cat eyes. Some of the silk-shaped inclusions of cat eye are rutile and some are empty tubes. Because these tubular inclusions are slender and dense, the cat eye effect is particularly obvious, even if it is very clear under a weak light source, which is incomparable to other gems.

Artificial cat eye is made of glass fiber, with red, blue and brown yellow, among which some brown yellow varieties are like natural cat eye. The difference between the two is: artificial cat eye stones have two to three bright bands at the top of the curve, while there is only one natural cat eye stone. When you observe both sides of the artificial cat eye stone with a magnifying glass, you can see a hexagonal honeycomb structure. At the same time, artificial cat eye stones have lower hardness than natural cat eye stones.

Use a single light source to illuminate the side of the cat's eye. The colors on both sides of the cat's eye are different. When illuminated with yellow cat's eye from the left, the left side is honey yellow and milky white on the right side. When illuminated with the right side, the colors are exactly the opposite.

The information about the cat eye stone flashed through Hao Huai's mind, but something surprised him because the necklace was already in his right hand, but the ring did not move at all.

"What's going on?" When Hao Huai was wondering, Sun Domain name on the opposite side was already laughing.

"Hao Huai, I've seen the things. If you can't say that you are Ziwu, Maoyou, then you will be tied."

Hao Huai suddenly thought something, and he was wise in a hurry and immediately slid the "cat eye" on the glass cover of the watch. Sure enough, scratches appeared on the cat eye and the glass cover at the same time.

"Sun Domain Name, it's not appropriate to fool your girlfriend with artificial cat eyes, right?"

The reason why Hao Huai made the move just now was because the ring did not give any prompts, which made him think that this thing was probably an artificial cat eye, that is, glass.

If this is the case, the friction between glass will definitely lead to a loss-win situation.

Of course, this is because of the same hardness. Not to mention gems, even ordinary crystal-tired semi-precious stones have higher hardness than glass. Therefore, those semi-precious stones and gems will not wear any wear when scratching glass, and will only scratch the surface of the glass.

After Hao Huai finished speaking, Sun Yuming was still stunned on the spot.

Xiaoli, the daughter of Sun Yuming, understood the truth when she saw her boyfriend's appearance. After seeing the eyes of the people around her, her face was suddenly red with shame. He couldn't help but twisted Sun Yuming's arm hard.

"Sun Yuming, you bastard, what kind of glass thing did you fool me?"

"My sister spent all the money given to me this month, and I can't do anything about it..."

Sun Yuming endured the pain and explained for a long time before comforting Xiaoli. Then he saw Hao Huai in front of him looking at him with a smirk, and the classmates around him looked at him in unison.

A group of students were very happy about the three-day free canteen dining, and now they also want to see if Sun Yuming, the guy, would let his girlfriend Xiaoli kiss Hao Huai in a wheelchair.

Seeing that the classmates around him were making excuses, Sun Yuming didn't want to leave a title of being untrustworthy, he whispered in the angry Xiaoli's ear: "Dear, just feel wronged and kiss that boy casually."

"Dimension Sun, you..."

Xiaoli looked at Sun Yuming with a pout, then looked at Hao Huai in front of her. Her confident look added a special attraction to his originally unsexy face, and the unruly smile made that attraction even stronger.

"If you kiss me, he wants to be willing. Maybe I will be his girlfriend."

Xiaoli looked indifferent and looked at Tang Feier beside Hao Huai, thinking, "If you steal my boyfriend, I will steal your boyfriend, and you will be so angry that you are vixen."

Hao Huai saw Xiaoli swaying her buttocks towards her, and she couldn't help but look at Tang Feier with a smirk. Her pretty face obviously changed, and her hands tightly seemed a little nervous. It seemed that she was still worried that Hao Huai would really let Xiaoli kiss her, and it was under the gaze of so many classmates.

"Forget it, I'm not interested in your kiss." Hao Huai smiled and pulled Tang Fei'er over and printed the fragrant kiss on her lips.

Shadow did not go to see Hao Huai and Tang Fei'er, but the students around him gave a burst of applause. Xiaoli stomped her feet with shame on her face, and Sun Yuming's face was not much better. She took Xiaoli's hand and turned around and disappeared into the applause of the students.

"Hey, these two guys are running fast, our three-day free meal is ruined."
