"Who can say for sure? Let's ask when we get back." Xiang Yang said with a smile.
Xiang Yang thinks it is inaccurate to say that because its color is beautiful, the price must be expensive.
Because tourmaline is a gemstone whose quality is not determined by color.
Tourmaline has many colors. Since tourmaline is a complex borosilicate mineral, the ions of some metals such as iron, magnesium, lithium, manganese, and aluminum can replace each other. The different contents of each ion will directly affect the color of the tourmaline, as well as its different types.
For example, if there is more iron, the tourmaline will appear black and green.
If there is more magnesium, it will appear yellow or brown.
For example, if there are more lithium and manganese, the color will appear rose red or blue, etc.
Although azure, bright red rose and red tourmaline can all be considered top quality, the uneven distribution of ingredients in the same tourmaline crystal often leads to color changes, so tourmaline can also appear in various types such as two-color tourmaline, multi-color tourmaline, or watermelon tourmaline with red inside and green inside.
Therefore, the price of tourmaline with pleochroism is not determined by color.
Xiang Yang looked at Chen Qingsheng and joked, "I see you can't let go of this tourmaline. Do you want to buy it for 10,000 yuan?"
Chen Qingsheng quickly returned it to Xiang Yang, "Boss, this is not fair. Let's not talk about how much a tourmaline of this quality is worth. You are not even sure if it is a tourmaline, but you sold it to me for 10,000 yuan. It's too unfair."
Xiang Yang laughed, "Once I'm sure, the price might not be this high."
Chen Qingsheng shook his head. "If it's 500 yuan, I'll take a gamble. If it's more than 500, I won't take it."
Xiang Yang rolled his eyes. "Five hundred dollars, unless this thing is a piece of glass, otherwise you will make all the money. Do you think I will bet with you?"
"In fact, it is very simple to determine whether this thing is tourmaline." Xiang Yang said.
Chen Qingsheng asked doubtfully: "Boss, do you know how to identify?"
Xiang Yang shook his head and said, “In the mall, I don’t know how to distinguish the authenticity because today’s counterfeiting technology is so advanced. I don’t know much about tourmaline either. But if I come across something that looks similar outside, I should have no problem identifying whether it is tourmaline or not.”
Xiang Yang told Chen Qingsheng the principles of identifying tourmaline.
It turns out that tourmaline is also called tourmaline because it has piezoelectric effect and thermoelectric effect.
What does it mean
When tourmaline is heated or pressured, or rubbed with silk or wool, an electrode effect is created at both ends of the columnar tourmaline, with one end being positively charged and the other negatively charged. This causes the tourmaline to attract dust or small pieces of paper.
This magical power is the piezoelectric effect and thermoelectric effect of tourmaline, which is also the origin of the name tourmaline.
After listening to the principle, Chen Qingsheng suddenly understood. He quickly said, "Boss, shall we try it now?"
Xiang Yang smiled and handed the blue stone to Chen Qingsheng, "You smoke, you have a lighter, come and try it."
Chen Qingsheng didn't hesitate to take the tourmaline and then roasted it with a lighter.
After heating for more than ten seconds, the lighter became hot. Chen Qingsheng felt that the tourmaline was also a little hot, so he took out a cigarette from the cigarette box and squeezed some tobacco into the palm of his hand.
"Look." Chen Qingsheng held the heated tourmaline in his other hand and slowly moved it closer to the tobacco in his palm.
The tobacco in his palm did not move at all.
"Boss, the identification is complete. This is not tourmaline." Chen Qingsheng said.
"Your identification method is wrong. It has been delayed for so long that the tourmaline has become cold. Let me try." Xiang Yang took the tourmaline and rubbed it quickly on his clothes.
"Could it be a problem with the tobacco?" Chen Qingsheng asked.
"Impossible." Xiang Yang said immediately.
There is a story related to tourmaline. It is said that on a warm summer in 170, several children in Amsterdam, the Netherlands were playing with stones brought back by Dutch navigators. Suddenly, a child discovered these stones and analyzed the dust and grass clippings nearby. The children were very surprised and called their parents over to see. Sure enough, they found that these stones can really attract or repel very light objects, such as dust, grass clippings, etc., so from then on, the Dutch called it ash stone, and also used it to clean the ashes in the pipe.
Xiang Yang took the tourmaline and rubbed it quickly on his clothes dozens of times, then brought it close to the tobacco in Chen Qingsheng's palm.
The tobacco remained motionless.
The two of them stared at each other.
"Boss, could it be that this tourmaline is damp? How about we dry it out and try again?" Chen Qingsheng asked.
Xiang Yang frowned and said, "Forget it, I won't try it. I'll take it back and ask someone who knows about it."
"Haha, I caught it, Brother Yang, look, I caught this lobster." At this time, Fang Youqun held a big lobster in both hands and ran towards this side with his hands dancing.
"Hey, Brother Yang, what are you doing with the bottom of a beer bottle in your hand?" Fang Youqun asked with a puzzled look on his face.
"Hmm?" Xiang Yang and Chen Qingsheng both looked at Fang Youqun.
Xiang Yang's face turned dark. If Fang Youqun hadn't said it, he wouldn't have noticed that the more he looked at this thing, the more it looked like the bottom of a beer bottle, except that the edges had been smoothed by the constantly rolling fine sand.
Chen Qingsheng shouted, "If you don't understand, shut up. This thing is called tourmaline."
"Bixi? I've only heard of Qingdao and Yanjing, oh, and Budweiser." Fang Youqun wondered.
Xiang Yang turned his head silently and looked at Chen Qingsheng, "I'll sell this thing for 500 yuan, do you want it?"
Chen Qingsheng looked at Fang Youqun, then at Xiang Yang, and finally at the blue object.
"You know what, the more I look at this thing, the more it looks like the bottom of a beer bottle. Could it really be the bottom of a beer bottle?" Chen Qingsheng said speechlessly.
Xiang Yang nodded silently. It was so embarrassing. Although he knew that among all the marine knowledge, organic gems had always been his weak point, but he still took the bottom of a beer bottle as a tourmaline and did a lot of experiments with Chen Qingsheng to test its authenticity with relish. Xiang Yang now wished he could find a crack to crawl into.
Chen Qingsheng's face turned green. He turned around and looked at Fang Youqun unhappily, "You don't even know Bixi. You've obviously never drunk beer. Don't tell anyone that I know you. Bixi is the Moutai of beer."
Fang Youqun scratched his head, "Really? It turns out to be high-end beer. No wonder a bottle of it can sell for 500 yuan. This beer must sell for tens of thousands of yuan a bottle, right? I don't know when I will have the chance to try the taste."
"You have no chance. This wine costs millions per bottle." Chen Qingsheng said expressionlessly. (To be continued)
