Ke Peijun saw Ding Mu take out a cloth bag and throw it on the coffee table, so he asked, "What is this?"

Ding Mu said casually: "It's all diamonds." Pen ~ Fun ~ Pavilion www.biquge.info"

The old lady said outside, "Bing'er, bring mine and bring in my jewelry identification tools and take a ten-fold magnifying glass." ”

Ding Mu knew a little bit about this, and as soon as he heard it, he knew that this old lady turned out to be a very knowledgeable person, so he asked curiously, "Madam, are you yourself an appraiser?" Finally, he showed a confident smile: "I am a registered appraiser of the Global Jewelry Association, and I am also the first batch of registered Chinese. ”

Ding Mu knew the gold content of the other party's identity as soon as he heard it. Although it is unexpected, it is reasonable that a real lady like the old lady can learn such a thing as jewelry appraisal is a matter of course.

It is the eldest lady of the aristocratic family who has a natural advantage over jewelry identification, fashion design, and this trendy thing, after all, people have seen a lot since childhood.

Ding Mu gave Ke Peijun a thumbs up and said, "It turns out that you are a master appraiser, then please appraise it and see how much these diamonds are worth to me, of course, you will definitely give a fair price." His purpose in saying this is also very simple, after all, the relationship between the two people is now buying and selling. If Ke Peijun said that these things were not valuable, then Ding Mu would not sell these diamonds. It's just a matter of paying in cash.

Of course, Peijun knew what Ding Mu meant, and she said lightly: "Don't worry, young man, I'm just giving you a reference price." You still have to find an authoritative appraisal agency, or go to auction to sell. I'll help you see how those things are, it's just a momentary itch. ”

When Mrs. Ding Mu said this, Ding Mu grinned and expressed his understanding, if he was the first batch of jewelry appraisers, he would have the same psychology as the old lady.

Ke Hanbing's movements were very quick and efficient, and after two or three minutes, she walked in with a tray covered with velvet. On the tray are placed gloves, a ten-fold magnifying glass, a color card, a white diamond lamp, an electronic balance and a variety of simple and practical identification tools.

The old lady put on her gloves, turned on the white light, and said to Ding Mu, "Take out your diamonds, and I will identify them one by one." You can write my estimate on the side, and then go to a third party to compare it, so that you can do a double check, and you can get a basically reasonable price. If you do have a treasure, you can put it up for auction, so you may be able to make more money, but it's up to you to make a bag

Ding Mu said: "It's okay, my cash is enough, and I will make up the difference in cash!"

Ke Peijun nodded and motioned for Ding Mu to take out the diamond.

Ding Mu directly grabbed the bottom of the bag containing the diamonds with his hands, and with a bang, he poured out all these diamonds like pinballs, and said: "These diamonds are not small, basically there are no less than five carats, they are all small pigeon eggs." Seeing that Ding Mo casually poured out hundreds of millions of diamonds, but Peijun is eyes jumped wildly, even if he didn't treat diamonds like this, this kid must be from a wealthy family.

Ding Mu is not from a wealthy family at all, but because this thing came too easily. If you get something easy, you don't know how to cherish it.

The old lady picked up the diamonds one by one, then looked at them with a ten-fold magnifying glass, and then evaluated the color with a color card under a standard white diamond lamp, and measured the weight on an electronic balance.

Ding Mu said to the old lady, "Madam, what are you looking at with a magnifying glass?"

Ke Peijun said: "The criteria for evaluating diamonds are that for a polished diamond, the international 4C standard is used for grading. The 4Cs include: Caratage, Clarity, Color and Cut. Each standard has a different grading system for different institutions, which was established in 1953 and is one of the first standards. We evaluate diamonds by nothing more than evaluating these four criteria. ”

"Which of these four criteria is the most important?" Ding Mu asked casually.

"What do you say?" the old lady did not reply directly.

Ding Mu thought for a moment and said, "That must be the weight." ”

"That's right. Weight is the most important factor in determining the price. And, if you're an experienced grader, you don't need a scale, you just need your eyes to roughly estimate the weight class of the diamond based on its size. Especially with a standard brilliant cut, the weight and carat size of a diamond can be easily estimated. The diameter of a 10-minute drill is 3mm, 75 minutes is 6mm, and 1 carat is 6.5mm. ”

"Oh, I see, so why use a 10x magnifying glass instead of a microscope?" Ding Mu said curiously.

"That's because the standard for evaluating clarity is a 10x magnifying glass. There are probably several levels:

? FL Flawless means that the diamond is clean when viewed under 10x gem magnification, i.e., there are no inclusions inside or outside the stone. This kind of rare is rare, and there are almost no in nature.

IF (internally flawless) means that the diamond is observed under 10x gem magnification without any blemishes on the inside, but there may be a slight blemish on the surface that can be removed by repolishing. This is extremely precious and can greatly increase the value of a diamond.

VVS is a very small imperfection that can be seen in the pavilion or surface of a diamond under 10x gem magnification. The difference between VVS1 and VVS2 is that the latter has tiny cotton dots and small stubble. This is usually a very good diamond.

VS Slightly Included Grade refers to very small imperfections that can be seen in a diamond under 10x gem magnification. The difference between VS1 and VS2 is that the latter may have tiny cotton dots or small stubble. This is the more common type of diamond.

The price is lower, and the SI small imperfection grade refers to the fact that it is easy to see the flaw when looking at the diamond under 10x gem magnification, which is basically visible to the naked eye. ”

Ke Peijun's speech was easy to understand and concise, and Ding Mu understood it at once: "It turns out that this is a perceptual understanding." He thought to himself that he was not able to grasp this standard, because his divine eyes saw things too clearly, and it had a microscopic effect.

"Huh. The old lady picked up a diamond and was a little surprised. She was holding in her hand the largest diamond in the pile, which was very obvious, and it was still a pink diamond.

Ding Mu saw that Ke Peijun was surprised, so he asked, "What's wrong?

The old lady appraised it, shook her head, and said, "This diamond is too precious, but its price is very difficult to evaluate." There have been no similar auctions in recent auctions. About the year before last, a foreign A-list star used a similar pink diamond when he got married, and its price was about 30 million US dollars. Hong Kong dollars, it will be about 300 million Hong Kong dollars. ”
