"The first thing to identify a diamond is to identify the authenticity, we can use the stroke method, the water drop method, the light refraction method, the thermal conductivity method, and of course, the certificate is also a method. Pen %Fun %Pavilion www.biquge.info"

Zhou Xian said as he took a pencil, first scratched on the 12-carat diamond ring diamond, and then scratched on the 20-carat diamond ring, and explained: "Real diamonds don't leave pencil scratches, and now it seems that these two diamonds are real!" ”

Zhou Xian looked very serious, and the female clerk on the side couldn't help but cover her mouth and laugh.

I've heard of authenticating diamonds, but I've never heard of people who already know that their diamonds are genuine, and then identify their own diamonds as fake.

Zhou Xian's serious words sounded a little unbearable to the female clerk, but in Wang Hao's sound, he couldn't help but secretly have a good impression of Zhou Xian in his heart, such a conscientious jewelry merchant is really difficult to see now!

Just looking at Zhou Xian's serious expression and a mentality of putting himself out of the way, Wang Hao has the idea that he may be able to cooperate with Zhou Xian in the future, but let's continue to see.

At this time, Zhou Xian first wiped the facets on the two diamond rings, then took a small clean toothpick, dipped a small drop of pure water, and put it on the facets of the two diamond rings.

"The droplets on a real diamond will take on a medium-sized round droplet shape, while the droplets on a fake diamond will spread out quickly! It's also a quick way to identify a diamond's authenticity! Zhou Xian said.

Sure enough, the two small drops of water and the diamond are not adsorbed at all, just like water droplets on the lotus leaf, showing a beautiful, translucent, oblate water bead.

"It's a real diamond!"

Zhou Xian was satisfied with the cotton cloth to absorb the droplets, took out the pen again, and introduced: "This is a diamond fire pen, which is used to identify the refractive property of diamonds. ”

Turn on the fire pen, the tip of the pen shoots out fiery red light, after the light hits the diamond, it immediately refracts the dazzling fiery red colored light, and the colored light spreads out on the desktop, like a peacock opening the screen, no, this is more amazing than the peacock opening screen!!

"With this method, it was concluded that both diamond rings are real!" Zhou Xian said seriously.

The last simple method of identification is the thermal conductivity method.

"Diamonds are the most thermally conductive! Let's try it with a thermal conductivity meter! ”

Zhou Xian took out the thermal conductivity pen, opened it and warmed it up for a while, and then pointed on the two diamonds, and the thermal conductivity pen made a chirping sound.

"It's true! Only real diamonds conduct heat so quickly, and it looks like this 20 carat diamond is of better quality! Zhou Xian commented.

Wang Hao smiled slightly, it seems that the first step is certain, the diamond he created with the system is a real diamond! The second step is to grade the diamond.

Zhou Xian's expression at this time was also a little excited, after confirming that the diamond ring sent by Wang Hao was genuine, as a businessman who loves jewelry, he couldn't refuse the temptation brought by this diamond, and at this time he wanted to reveal the true face of this 20-carat diamond ring more than Wang Hao.

"Hehehehehe!" Zhou Xian laughed, rubbed his hands, and congratulated: "Wang Hao, according to my preliminary estimate, the value of your diamond ring may reach the level of 10 million yuan!" Congratulations! ”

Wang Hao nodded, what he cared about was not 10 million, but the rating of the diamond ring, such a diamond ring, he could make a lot of it in minutes, but if it was not recognized by the outside world, then it was very likely that it would only be regarded as an artificial diamond, rather than a diamond of amazing value.

"Lao Zhou, you don't have to bother with grading this 12-carat diamond, right? Just give me the certificate, you mainly give me an appraisal of the quality of my diamond ring! ”

After saying this, Wang Hao said to the female clerk again: "How to pay?" Is it a payment order or a POS machine? ”

The female clerk said, "It's all right!" But it's better to use Alipay, I'll go and get that QR code, you just scan it. ”

"Hmm!" Wang Hao nodded.

At this time, Zhou Xian suddenly stood up, shook his head and said, "No, Weiwei, you wait a minute!" ”

The female clerk stopped.

Zhou Xian nodded respectfully to Wang Hao and said, "Wang Hao, did you give you this 20-carat diamond ring from someone else?" ”

"It's not someone else's gift, and it doesn't have any special significance, I just want to know its true value and see if it's worth my collection!" Wang Hao said.

Zhou Xian's eyes lit up, and he immediately asked: "I don't know if your diamond ring is for sale, I want to acquire it as a new treasure in my store!" If there is such a big diamond ring in the store, it will bring a lot of popularity to my store! ”

Sell?

Wang Hao didn't think about selling it before he came!

He doesn't have a diamond mine yet, and he doesn't plan to start selling diamonds, but he just wants to confirm a small direction for future development through the opinions of professionals in the industry.

However, it seems that Zhou Xian really wants to have this diamond ring!

"Let's test it first, now that you want to buy it, the rating of it will definitely be more realistic." Wang Hao said.

Zhou Xian nodded, "Yes, yes!" Test first! ”

Professional microscopes, cutting mirrors, hardness testers, and thermal conductivity meters are used for testing.

These tools are all on the table.

In order to confirm the impartiality, Zhou Xian still passed his 12-carat diamond ring through various professional tools to confirm the data, and only then put it under the microscope after completion.

"The rating of diamond rings is generally from four aspects, the first is the weight, the heavier the better, 1 carat = 0.2 grams = 100 points, and diamond rings with more than 10 points should be marked with a diamond grade when they are sold!"

"The grading of colored diamonds is not mentioned here, white diamonds are divided according to color, from high to low, generally divided into five grades: extremely white, excellent white, white, light yellow and white, and light yellow!"

"Generally, the white diamonds that circulate in large quantities on the market are mainly white, light yellow and white. The worst light yellow will not sell for much unless the monomer is heavier. And the two levels of extreme white and excellent white are very rare. ”

"Then there's the cut of the diamond, which is divided into very good, good, and average."

"There are five levels of clarity from high to low, LC (Flawless), VVS1-VVS2 (Very Slightly Fine) VS1-VS2 (Slightly Fine) SI1-SI2 (Small) P1-P2-P3 (Flower Grade)"

……

The data of the treasure of the town store in Zhou Xian's store is as follows:

Weight: 12 carats (1200 points)

Color: Youbai (Level 2)

Clarity: VS1 (the best of the five out of three)

Cut: Good (2nd grade)

Wang Hao's diamond ring data is as follows:

Weight: 20 carats

Color: Extreme White (Top)

Clarity: LC (Top, also known as Flawless)

Cut: Very Good (Top)

When Zhou Xian finished recording the last data, he couldn't hold back any longer, his expression was shocked, and he suddenly stood up from his chair, holding two lists, and his eyes widened to confirm whether he had made a mistake just now

"Oh!! …… I can't believe this data is real!! I'll test again!! ”

Zhou Xian was even harsher this time, even so harsh that he felt that he was too much, and that look seemed to say: "Nima, I'm like this, will Wang Hao beat me?" ”
