The fat man who was talking nonsense was naturally picked up by Yang Jing and Lin Dan, and several bodyguards were holding their arms to watch the excitement.

After making a fuss, the fat man said, "Old Yang, how much are these eight gems worth?"

Yang Jing looked at Lin Dan, when Lin Dan said purple diamonds and pink diamonds just now, he had shown his understanding of jewelry, it seems that this kid is not only familiar with mining, but also familiar with luxury goods.

Feeling Yang Jing's gaze, Lin Dan cleared his throat and said, "Let's not talk about this purple diamond, 50 million US dollars is guaranteed." Well, look at this pink diamond, my God, Brother Yang, I really envy you, how do you buy some excellent things. ”

Lin Dan said, pinched up a piece of colorless rough diamond and said: "Look at this colorless diamond, this color has definitely reached the top D grade! As for the clarity, I estimate that even if it is not the top FL grade, at least it must be IF grade!"

Diamonds come in a variety of natural brilliance, ranging from precious colorless (cut white) to rare light blue, pink to yellowish. The brighter and more colorless it is, the more the white light can penetrate, and the more colorful it is through refraction and dispersion. Diamond Glory Grading is determined by a technician repeatedly comparing the diamond to be graded with a standard Glory Master Stone in the professional execution room. The whitest diamond is rated D, that is, starting from the first letter of Diamond, it is divided into 11 grades: D, E, F, G, H, I, J, K, L, M, N.

Clarity is another important criterion for judging the preciousness of a diamond. The FL grade, that is, the flawless grade, mentioned by Lin Dan just now, refers to the fact that there are no flaws inside and outside when observed by professionals under 10x magnification, which is the rarest and most precious among all clarity grades.

Of course, Lin Dan only relies on visual inspection to judge the grade of this rough diamond, what is the actual grade, and it also needs to be highly complicated by professional technicians to give the most accurate answer.

However, Yang Jing knows the color grade of these two colorless diamonds, and the holy ring has given a "colorless" identification answer, that is to say, these two rough diamonds are the best D-grade colorless diamonds.

Lin Dan picked up another piece of colorless rough diamond and looked at it and said: "There is no difference between this rough and that one, except for the difference in size, this rough diamond is also the best colorless diamond." Well, both of these rough stones are almost over 50 carats, and if you find a master cut, this small one can cut a 20 carat diamond, and this big one can cut out a diamond of about 24 to 25 carats. We all know, let alone 20 carats, even diamonds over 10 carats are relatively rare, these two diamonds are so big, plus their purity and clarity are so good, so these two diamonds alone, I estimate that at least 40 million dollars!"

Lin Dan put down the two colorless diamonds, picked up the pink diamond again, shook his head with a wry smile and said: "This pink diamond is also amazing, whether it is color or clarity, it is the best! If this pink diamond is cut, it is estimated that it can produce at least a pink diamond of about 15 carats." The Graf pink diamond I was talking about at Sotheby's auction, although it weighed a staggering 25 carats, was only VVS2 in clarity, which is a very slightly flawed diamond. Although our pink diamond is not as big as the Graff pink diamond, I think our pink diamond has better clarity and more brilliant color, so I guess this pink diamond should be no worse than the Graf pink diamond if it were auctioned! That is, the conservative estimate of this pink diamond should be 45 million dollars!"

The fat man listened and silently calculated in his heart, and as soon as Lin Dan finished speaking, the fat man covered his head and said: "Xiao Linzi, according to your estimate, these four diamonds alone are almost 125 million? I'm talking about dollars!"

Lin Dan nodded and said: "This is my estimate! The main reason why the price is so high is that these four little guys are too big, and the color and clarity are too good! Such a rough diamond, any one taken out is the best, and it is not surprising that the value is so high." Of course, the real value of these four diamonds depends on the professionals. But I think the real value of these four diamonds should be only higher than I said!"

After a pause, Lin Dan said with great certainty: "Let's not say anything else, just that purple diamond, if Brother Yang is willing to get it auctioned at auction, it will definitely be able to fetch a sky-high price! The ten-carat purple diamond, which has never appeared before, will definitely make the vast majority of rich people in this world crazy!"

Yang Jing said with a smile: "I am reluctant to take out such a precious purple diamond for auction! Anyway, I am not short of money now, and I am still going to keep these two colored diamonds for my daughter-in-law to make jewelry!"

The fat man saw Gege, and when he heard the words, he immediately gave Yang Jing a thumbs up.

Of course, the fat man also knows Yang Jing's current net worth, these diamonds are precious, but Yang Jing will not take them out for auction. This guy has good things that are kept for his family and daughter-in-law. He is not short of money, and he does not need to auction these things to get money at all.

Lin Dan picked up another rough sapphire and said: "Tsk, this sapphire is so hanging! It is definitely the best Sri Lankan star sapphire! Well, and those two rubies, they are definitely the best pigeon's blood rubies, but I don't know if they are from Myanmar or Sri Lanka." Look at the color, look at the clarity, it's absolutely top-notch! Especially when it's so big, it's amazing!"

The fat man asked, "Then you can also estimate the value of these four ruby sapphires?" ”

Lin Dan shook his head and said, "I won't value ruby sapphire, my understanding of ruby sapphire is not as thorough as diamond." ”

Yang Jing smiled and said, "Xiao Linzi, you can't look at these two sapphires." ”

"Isn't this the finest Sri Lankan star sapphire?"

Yang Jing shook his head and said, "If I'm not mistaken, these two sapphires are better than Sri Lankan star sapphires!"

Lin Dan was stunned when he heard this, and then as if he remembered something, he asked excitedly: "Brother Yang, could it be that these two sapphires are the legendary Kashmir sapphires?"

Yang Jing nodded and said, "That's right, these two rough sapphires are the legendary Kashmir sapphires." Look at the color of these two sapphires, the rich bright blue with purple in it, and it is as pure as the sky of the plateau, such a pure color is incomparable to the sapphires found elsewhere, only the legendary Kashmir sapphire can have such a pure blue!"

Although the fat man is not very proficient in gemstones, he has heard of the great name of Kashmir sapphire. "Lao Yang, if these two pieces are really Kashmir sapphires, then wouldn't we send them?"

Yang Jing smiled and said, "It's not very good, but it's very good." Between 1979 and 2008, a total of 150 high-quality sapphires appeared at auction venues around the world, of which 121 were identified as Kashmir sapphires, and the auction price per carat of Kashmir sapphires was about $39,000 to $135,000, which is already higher than most colorless diamonds, but still inferior to the finest colorless diamonds and fancy colored diamonds. ”

After a pause, Yang Jing continued: "However, in view of the fact that the number of Kashmir sapphires is too rare, especially these two pieces like ours, which are so big, if they are auctioned, I am afraid that the price will not be low." ”

Lin Dan also said: "Yes, ruby sapphire is different from diamond, in addition to color and clarity of diamond, cut is also a very important measure, but the cut of ruby sapphire is not so important, for ruby sapphire, color is the first, clarity second, as for cut, hehe......"

In order to make it easier for Chris to understand, Yang Jing said these words in English, so when Chris heard these words, he asked: "BOSS, I only knew that Sri Lankan sapphires were the best, but listening to you say this, isn't Kashmir sapphire much stronger than Sri Lankan sapphire?"

"As it stands, that's true. Yang Jing nodded, "Sri Lankan sapphires also have excellent quality, but even the best Sri Lankan sapphires are far behind Kashmir sapphires in value." Let me give you an example, at Christie's Geneva in 2014, a superb Sri Lankan sapphire weighing 27.54 carats sold for $600,000, but a year later at Christie's Hong Kong, a Kashmir sapphire of about the same weight sold for $6.7 million. ”

When Chris heard this, he shook his head in surprise, "Such a big difference?"

"Well, that's the gap. Sapphires from Myanmar are also available, with a 114.74-carat loose Burmese sapphire selling for $7.2 million at Sotheby's Geneva in November 2013 and $7.35 million at Christie's Geneva in May 2015. One is a Burmese sapphire that is bigger than an egg, and the other is a Kashmir sapphire about the size of a quail egg, but the price is about the same, so you know the difference between the two. ”

The fat man asked, "Old Yang, you didn't tell the price of these four ruby sapphires." ”

Yang Jing shook his head and said: "These four ruby sapphires are the best of the best, and they are still so big, even if each one is cut with the simplest bread mountain, the finished product can almost exceed forty carats, and the larger ones can even exceed fifty carats! Such a large and superb ruby sapphire, especially such a large Kashmir sapphire, is too rare." Even if it's a sale, I don't know how much money I can get, and I don't have anything to learn from before. But I can be sure that the price of these four ruby sapphires is definitely not lower than that purple diamond!"

The fat man muttered to himself, "With these four ruby sapphires, these eight gems alone are worth almost $175 million?"
