Skyfire Avenue Chapter 125: Diamond
Lan Jue does not have said hello to the students, but walked behind the podium and set down a tray in his hands. Then he pulled out a small cloth bag from his arms, took something out of it, and put it on this tray.
After doing this, he turned around and wrote a few words on the blackboard, “Want a prize?”
Simple five words. At the beginning, only the previous students saw it, but soon, under the reminding of each other, the students in the class saw it all. The noise became smaller.
Lan Jue wrote the second line on the blackboard again, “You are too busy to draw.”
As soon as this line came out, the voice in the class suddenly quieted.
Wang Hongyuan eyes has a little more interest. Lottery? Really new. I don’t know what he will come up with. Although the class is quiet for the time being, but these are all college students, will the general prizes be seen by them in eyes? Once the prizes are not good enough, then the next rebound may be even greater.
He has been teaching here for several years, and he knows these students who come to elective course better. When he first came to class, he had no choice but to control the emotions of the students.
“Hello everyone.” Lan Jue saw that the classroom was quiet, and then came out from behind the podium and bowed to all the students.
Jin Tao stood up first, then Tang Xiao. The two who stood up immediately followed them, indeed Tang Mi and Zhou Qianlin.
Shui Zhongdie also stood up in surprise. The three Big Beauty all stood up. Naturally, the male students who came here also stood up. Once they had been to the Lifestyle Class, Lan Jue. The students who knew him also got up.
“Teacher Lan is good.” Jin Tao almost shouted these words.
Then there were jagged hellos in the class.
Lan Jue makes a downward movement with both hands. “Please sit down.”
Students sit down again. Jin Yan kicked nearby Wang Hongyuan gently. “Teacher Wang, why don’t you stand up? Since we come to the class, that’s the students. Moreover, if we are still colleagues, if we don’t support Teacher Lan, how can we set an example for the students.”
Wang Hongyuan smiled indifferently, pinched an orchid finger, “I didn’t respond.”
Jin Yan poked his lips. No more snoring.
Lan Jue walked back to the podium, pointed to the words on the blackboard, smiled and said, “Raffle, this is true.”
“Everyone must be guessing what prizes are drawn today. So, I believe you will not be disappointed. Remember I told you at the end of the last class, what did this class tell you? “
“Gem!” A girl yelled out below immediately.
Lan Jue gives a thumbs up, “Yes, today I will tell you about gems. The knowledge about gems is very complicated. There are many kinds of gems. There are also many categories. One lesson is impossible to finish. So, we will today I only talk about one of them. If you are interested in words, I will continue to talk about the other in the future. “
While talking, Lan Jue erected the tray in front.
The surface of the tray is dark blue velvet surface, indeed Zeus’ Jewelry Store own display plate. At this time, there was a glittering gem on it.
The gem is crystal clear and white. On that dark blue velvet surface, it looks like a eye-catching star in the night sky.
“Who can tell me what is this?” Lan Jue smiled.
“Diamond.” Shui Zhongdie on the right side of Zhou Qianlin blurted out, her voice was very nice, pleasant and melodious. The Zhou Qianlin is less gentle, but it is a bit more crisp.
“Yes.” Lan Jue nodded to her, “This is the gemstone, one of our more common type, the diamond. Today we are talking about it. This diamond is the last prize today.”
Wow, the exclamation sounded one after another. Use a diamond as a prize? I’m afraid this has never happened in the entire Hua Alliance National Academy teaching history.
The Wang Hongyuan sitting in the back freezes suddenly. With his eyesight, I can naturally see that this diamond is as large as a carat. Although it cannot be said to be particularly valuable, it is definitely not cheap.
Lan Jue pointed at the second line written on the blackboard with his finger.
This time the classroom’s quiet speed is much faster than before. The attention of all students was almost attracted to Lan Jue.
“There is a saying,” Diamonds are long-lasting, and one will last forever. I believe everyone has heard of them. Although this is just a slogan, in fact, it also tells a characteristic of diamonds. Then It’s the firmness and abrasion resistance of diamonds. “
“I’m not Chemistry Teacher or Physics Teacher, so I won’t tell you about the composition of diamonds. What I want to tell you is that diamonds are very hard. Without counting energy gem, diamonds are the hardest of other gems. One kind. If its hardness is ten, then the ruby and sapphire that we are familiar with are about nine, and the jadeite is seven. The Hetian jade of Former Era Ancient China is close to seven. The hardness is more than seven and it is jadeite. Below seven, it is nephrite . Therefore, Hetian jade can only be called nephrite. “
“I ’m talking about gemstones for the first time today, and I do n’t want to instill too much knowledge. You only need to know that diamonds are the hardest. So, we general like to use it for wedding rings. It is wear-resistant and can last longer. Preservation is not easy to damage. It also symbolizes the eternal love. “
Lan Jue‘s voice is very magnetic and speaks fast and slow. What is said is very simple, every academy present here can be easily understood.
Lan Jue walked down with a tray and sent it to Jin Tao. “Pass it back, every student please look at this diamond.” A smile on reveals, “Please also supervise Oh, this one. The diamond is to be sent. It doesn’t matter to me if I lose it. anyway is will give it to you. But others can take the opportunity of does not have for Oh. “
A little joke, immediately relaxed the atmosphere in the class.
Don’t care about the diamonds passed back, Lan Jue walked back to the podium, and said, “The diamond hardness is finished, so what I will introduce to you today is the standard for judging the quality of diamonds. This is first of all, Size. generally speaking, almost all gems, including energy gem, are directly proportional in value and size. That is, larger gems are more expensive, and smaller and cheaper. This also applies to diamonds. “
“Therefore, if a diamond wants to have collectible value, it must be at least one carat. 0.99 carats, compared with one carat, there will be a large price gap. Today I bring this one, indeed A standard one carat. If it is two carats words, the price is not one plus one equals two, but a geometric multiple increase. And so on.
“In addition to the size, the quality of the diamond is judged by several other standards of also. In short, is the same value for a one-carat diamond? Is the answer no, the quality is different, and the price will be much worse? Oh. “
The tray has now begun to pass backwards. Almost all students know diamonds, but it is the first time to observe diamonds at such a close distance and hear people tell about the characteristics of diamonds. The vast majority of students were aroused.
“In addition to size, there are three main criteria for assessing the quality of a diamond. The first is color, then clarity, and finally cut.”
“First of all, in terms of color, in addition to colored diamonds, the color of the diamond is naturally the whiter. The alphabet is arranged from low to high. The highest grade is d. d means 100% pure white. It can be said to be the perfect color. Then e, e is ninety-nine colors, which is almost close to perfection, and then f, ninety-eight colors. These three color levels are known as the 1st Step ladder of diamond colors. After that, g, h , I, j, k and so on, the later the letter is, the more yellow the diamond itself is, the cheaper it is. It is also a one carat diamond, and the d color is at least three times the price of the i color. This is the color Gap. Of course, generally speaking, there is no need to pursue perfection. The three colors d, e, and f are not easy to see without comparison.
“The diamond I brought today is f color, it is already very white.”
While the passing of the diamond, Lan Jue talked about it and wrote down the key points on the blackboard.
Next, he explained the clarity and cut of the diamond in a simple way …
“A perfect diamond is the best in terms of color, clarity, and cut. This diamond, which we call perfect, is also called flawless! flawless diamond is where it comes from . “
time unknowingly passed, and all kinds of knowledge about diamonds were also instilled in the students present.
After a round of passing, the diamond finally returned to the podium of Lan Jue.
“I know, everyone is waiting for this moment to come. Although you can rest assured, the Teacher Lan speaks absolutely countless. Below we will start the lottery.”
Lan Jue puts the tray in front of himself. “The way we draw today is relatively simple, in order to ensure fairness. Everything is operated by the students present.”
While talking, he sent the paper prepared earlier, “Please write your name on the paper, and then collect it together later. Then we will put it in a box. One is drawn out, and who the name is, this diamond belongs to it. “
Soon, the paper is collected again. Lan Jue puts the prepared box on the podium, puts the paper in it, shakes it first vigorously, and then probes it and pulls out one.
“Okay, let me announce that the winning classmate is Zhou, Zhou Qianlin!” When Lan Jue read the name, he even froze.
Couldn’t it be such a coincidence? The winner of the diamond turned out to be Zhou Qianlin.
The Zhou Qianlin sitting below was also a little stunned, but many male students sitting behind her all waved their arms and looked excited.
Lan Jue suddenly felt something wrong, eyes flashed a faint blue, and spiritual power quietly probed into the carton and swept around.
He saw forty-two Zhou Qianlin in all the more than one hundred notes …
I also recently bought a diamond for my 60th birthday present! Hehe. My dad also reads my book. If you see it, don’t tell mom.
Ask for a monthly ticket, a recommendation ticket. (To be continued …)
