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

Ding Mu said casually: They are all diamonds.

The old lady said to the outside: Bing'er, bring in my jewelry appraisal tools and a ten-fold magnifying glass.

Ding Mu knew a little about this aspect, and upon hearing this, he knew that the old lady was a very knowledgeable person. He asked curiously: Madam, are you an appraiser yourself? But the old lady. Finally, he showed a confident smile: I am a registered appraiser of the Global Jewelry Association, and I am one of the first batch of registered Chinese.

Ding Mu knew the value of the other party's identity as soon as he heard it. Although it was unexpected, it was reasonable for a real lady like Mrs. Ke to learn jewelry appraisal as a matter of course.

It is the kind of eldest lady from an aristocratic family who has a natural advantage in jewelry appraisal, fashion design, and other trendy things. After all, she has seen them a lot since she was a child.

Ding Mu gave Ke Peijun a thumbs up and said: So you are the master of appraisal, so please appraise it and see how much my diamonds are worth. Of course, you will definitely give me a fair price. Price. His purpose in saying this was very simple. After all, the two people were in a buying and selling relationship. If Ke Peijun says that these things of his are not valuable, then Ding Mu will not sell these diamonds at worst. Just pay in cash.

Of course, Ke Peijun knew what Dingmu meant. She said calmly: 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 an auction to sell it. Let me take a look for you. What are those things like? It’s just a temporary itch.”

Old lady Ding Mu said this, and Ding Mu smiled and expressed understanding. If he were one of the first jewelry appraisers, he would have the same mentality as the old lady.

Ke Hanbing's movements were swift and efficient. In two or three minutes, she walked in with a velvet-covered tray. On the tray are gloves, a ten-fold magnifying glass, color comparison cards, white diamond lamps, electronic balances and other 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 appraise them one by one. You can write my estimate on the side, and then go to a third party to compare them. Yes, in this case, if you do a double check, you can get a basically reasonable price. If you really have treasures, you can go to auction, and you may be able to earn more, but just for your bag

Ding Mu said: It doesn't matter, I have enough cash, and I will make up for the difference in cash!

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

Ding Mu directly picked up the bottom of the bag containing the diamonds with his hands, and with a crash, poured out all the diamonds like pinballs, and said: These diamonds are not small, basically none below five carats, they are all They are little pigeon eggs. Seeing Ding Mo casually pouring out diamonds worth hundreds of millions, Peijun's eyes were twitching wildly, even he would not treat diamonds like this, this kid must be He comes from a wealthy family.

Ding Mu was not born into a wealthy family at all, but because this thing came too easily. Don’t cherish things that come easily.

The old lady picked up the diamonds one by one, observed them with a ten-fold magnifying glass, and then used a color chart to evaluate the color under a standard white diamond lamp, and measured the weight with an electronic balance.

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

Ke Peijun said: The standards for evaluating diamonds are: For a finished diamond, the 4C standard is used internationally for grading. The 4Cs include: Caratage, Clarity, Color and Cut. . Different organizations have different grading systems for each standard. This grading system was established in 1953 and is one of the earliest standards. Our evaluation of diamonds is nothing more than evaluating these four standards.

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

What do you think? The old lady did not answer 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 price. Moreover, if you are an experienced appraiser, you don't need a scale. You only need your eyesight to roughly estimate the weight of a diamond based on its size. Especially in standard brilliant. After cutting, the weight and carat size of a diamond are easy to estimate. The diameter of a 10-point diamond is 3mm, a 75-point diamond is 6mm, and a 1-carat diamond is 6.5mm. In fact, the sizes of various cuts are available in tables.

Oh, I see, then why do you need to use a 10x magnifying glass instead of a microscope? Ding Mu asked curiously.

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

?FL flawless level (flawless) means that the diamond is clean when viewed under a 10x gemstone magnifying glass, that is, there are no inclusions inside or outside the gemstone. This kind is very rare and almost does not exist in nature.

IF flawless (internally flawless) means that there are no flaws inside the diamond when viewed under a 10x gemstone magnifying glass, but there may be a few flaws on the surface, which can be removed by re-polishing. This is extremely rare and can greatly increase the value of diamonds.

VVS Very Slightly Blemishes grade means that when the diamond is observed under a 10x gem magnifying glass, very small flaws can be seen in the pavilion or surface. The difference between VVS1 and VVS2 is that the latter has tiny cotton-like spots and small stubbles. This kind of diamond is usually considered a very good diamond.

VS Slightly Blemishes grade means that very small flaws can be seen when observing a diamond under a 10x gemstone magnifying glass. The difference between VS1 and VS2 is that the latter may have tiny cottony spots or small stubble. This is a relatively common diamond.

The prices further down will be lower. The SI minor flaws level means that it is easy to see flaws when observing the diamond under a 10x gemstone magnifying glass, which can basically be seen with the naked eye.

But Peijun's words were easy to understand and concise, and Ding Mu understood immediately: It turns out that this is a perceptual knowledge. He thought to himself that he still couldn't grasp this standard because his spiritual eyes could see things too clearly. Has a microscopic effect.

Huh. The old lady picked up a diamond and was a little surprised. What she held in her hand was the most obvious and largest diamond in the pile, a pink diamond.

Seeing Ke Peijun's surprise, Ding Mu asked, What's wrong? Is there something 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 is no similar thing at the recent auction. About the year before last, there was a foreign first-line diamond A similar pink diamond was used when a celebrity got married. Its price is about 30 million US dollars. In Hong Kong dollars, it is about 300 million Hong Kong dollars.
