Sutra is a historic city for polishing and processing diamonds, and has been working with diamonds for nearly a thousand years, Calabi has been in the diamond business for decades, and if you count the generations of his ancestors, their family has been in the diamond business for hundreds of years.

But he really hadn't seen such a big rough diamond, and he had only heard of it in legends.

When the original diamond of the 'Mountain of Light', a national treasure of India that was forced to be dedicated to the Queen of England, was discovered, it only weighed 800 carats, and 800 carats was converted into an ordinary unit of measurement, that is, 160 grams, less than two taels, which was about the same weight as the diamond in front of me.

Although I haven't gotten my hands on it yet, Calabi has been with diamonds for decades, and you can estimate how big a diamond is and what weight it weighs with a single eye.

At this time, looking at the diamond in front of him, he couldn't breathe anymore, panting, and his eyes began to redden, this diamond was obviously simply polished, although the shape was not regular, but it was also the oval shape of an egg.

The most uncontrollable thing for Calabi is that the transmittance of this rough diamond, to know the quality of a diamond, the transmittance is very critical, this rough diamond has not been specially polished and polished, and even in many places, it still has the original imprint, if it is processed by his factory, polished and polished, it is definitely the top one.

With such a large and complete piece and such a good quality, this diamond can definitely be said to be the best found in recent years, and it can even be said to be the top diamond that Calabi has seen in his career.

"Mr. Xiao, can I take a look?"

Calabi gasped and asked Xiao Feng, Xiao Feng smiled and nodded, no problem, casually pushed the original drill in front of Calaby, Calabi almost jumped up and hit someone when he saw his movements.

Although diamonds are the hardest substance in the world, this thing is very brittle, and it is fine to be smaller, although such a large one will not be broken if it falls to the ground, but if there is a crack, it will be a big loss.

But looking at the diamond in front of him, Calabi couldn't care about being angry with Xiao Feng, he quickly picked up the diamond, took out the glove magnifying glass from the small box next to him, and began to observe it carefully, after looking at it for a long time, this guy breathed a sigh of relief and put down the diamond in his hand.

"I don't see a laser code on the diamond?"

In the modern diamond industry, in order to continue to monopolize the diamond trade and control prices, De Beers, Rio Tinto, and Alrosa have formed an alliance. Lost diamond jewelry, because of the laser barcode, in the second-hand market is not easy to sell, the second is also to control the diamond trade, the current market trading diamonds, as long as there is no laser code, will be considered blood diamonds, from Africa or other mining areas of the black mine diamonds, not accepted by the mainstream diamond industry.

If such diamonds appear in the market, then practitioners can choose to call the police, and then block the circulation of diamonds from other black mines in the market, so as to make it easier for those giants to manipulate the market.

But on the black market, this kind of rough diamond without a barcode is the object of sought-after, because there is no barcode, this kind of diamond is equivalent to no ID card, and it is not easy to be tracked, so it is favored by many money laundering organizations, or drug lords, or corrupt politicians.

Because such diamonds do not have to worry about being tracked, they have a strong ability to liquidate, which makes them very popular on the black market.

The Calabi family has been in the diamond business for hundreds of years, and it is certainly not only a legitimate diamond trade, but also a black market trade, and even tens of millions of dollars of diamonds are circulated into the black market every year, but he has never seen a rough diamond in such good condition and so large.

Thinking of the profits that this rough diamond might bring, this Calabi couldn't help but take a deep breath, and then looked up at Xiao Feng, who was sitting opposite him smiling, and he suddenly felt an urge to eat black.

There is only one person in this Chinese kid, if you kill him, will you be able to swallow this rough diamond?

But after turning his head and thinking about it, is the person who dares to come to Marat alone to find himself and take out such a large piece of rough diamond without laser marking?

Think about it again, this man is Liukin. Deliuka introduced it, and the little devil who had just emerged in Calabi's heart quickly died down.

So what kind of person is Liukin, who was an arms dealer who was in the limelight back then, who was wanted by the CIA, and who is still alive and kicking around, can he be an ordinary person?

Maybe there is a Russian mafia behind them, and who is the Russian mafia? Is that a stubble that even the Italian mafia is afraid of? Now it is the most ruthless underground force in the United States!

And is this Chinese really that simple? Such a large rough diamond was made from that mining area in Siberia, and if you think about Liukin and the Russian mafia, maybe there is something to do with them.

So Calabi's crooked thought that had just risen didn't last more than thirty seconds and immediately died down, anyway, you can make money by passing it, so why bother stabbing that hornet's nest.

"Well, Mr. Xiao, I, Calaby, as a trustworthy businessman, can be very responsible to say that your diamond is indeed of top quality. If you want to make a move, at what price?"

Such a big diamond, as long as it is polished well and cut into small pieces, then you can make millions of dollars as soon as you change hands, so why mess with those crazy people for a little money? Calabi quickly figured out the account, so he also began to inquire directly.

"My diamond, which I measured before I came, weighs 880 carats when opened, and the quality is also top-notch. The most recent one should be the 'Our Light' found by Lukla Diamonds in 2015 at the Karlovi mine in Botswana, which weighed 1,109 carats and was successfully auctioned in London in 2017 for $53 million. My one, although not as big as that one, but my one is a rough diamond, and there is no laser mark, it should be more popular on the black market, so I think this one should also be worth $53 million. ”

Since he came to buy diamonds, of course Xiao Feng made preparations early, during this time he studied the market situation of diamonds thoroughly, so he gave such a quotation, of course, this price is obviously high, just to wait for Calabi to bargain.
