Chongzhen Emperor Zhu Youzhen and Zhang Huiyi were very happy, the two of them laughed softly, but they didn't know that this one was seen by Zheng Yuelin, who came out to shop, Zheng Yuelin's home was not very far from Zhang Huiyi's home, and Zheng Yuelin originally wanted to chat with Zhang Huiyi and talk about the affairs of tomorrow's court, but she didn't expect to see this amazing scene!

In Zheng Yuelin's opinion, Zhang Huiyi took the initiative to hook Chongzhen Emperor Zhu Youzhen's hand and walked, obviously the two of them were already like that, she was very uncomfortable, if the emperor didn't accept two people into the palace, and let two people be officials, it should obviously be fairer, obviously nothing should be done, why can you do this to Zhang Huiyi and to yourself?

In this game of love, women are stingy.

Zheng Yuelin left angrily, Chongzhen Emperor Zhu Youzhen and Zhang Huiyi didn't know, they arrived at the door of the house with a smile and a smile, just in time for Zhang Weiye to go out, Zhang Weiye saw that the inspector and his sister were like this, almost went crazy with joy, and was ecstatic! "Young Master, sister."

Zhang Huiyi was in a good mood at this time, she had already gotten along with the anger she had with Zhang Weiye just now, smiled lightly, and hurriedly let go of the hand that was still holding Xunlou's arm, "Brother." ”

Chongzhen Emperor Zhu Youzhen also smiled slightly, and nodded very elegantly, "Lord Zhang, I haven't seen you for a long time." ”

Zhang Weiye hurriedly saluted respectfully, "Young Master Jian is willing to go to the cold house, and he is carrying the thatched house, please hurry up, I was talking to my mother just now, and my mother also misses Master Jian very much." ”

Chongzhen Emperor Zhu Youzhen nodded, no matter who Zhang Weiye was, he rushed to this ability to communicate. Let Zhang Weiye be the prefect of Tianjin. And it's not too much.

Zhang's mother did see Jian Xun Lou this time. It's very different from before, the old people are all looking to their son, and now the son's future is in the hands of the inspector and the prince, and Zhang's mother can also see that her daughter really likes the young master, and she is very happy for this marriage.

Zhang Huiyi listened shyly and went back to the house by herself. Chongzhen Emperor Zhu Youzhen talked with Zhang's mother and Zhang Weiye for a while, and roughly revealed to Zhang Weiye that the new law was an imperative thing for the emperor, and Zhang Weiye was overjoyed! After Zhang Weiye left in the inspection building, he immediately went to report to Zhou Yanru! Emperor Chongzhen Zhu Youzhen returned to the palace by himself, and he did not go into detail.

Chongzhen Emperor Zhu Youzhen found his own mineral storage information, and he did not forget the development plans that he thought of when he returned to modern times when he was shopping with Zhang Huiyi today! First you have to get treasures, and then you have to become a monopoly! And then buy a helicopter gunship, buy a set of technology for producing bomber high-explosive bombs, and get a few more samples!

Diamond refers to diamond that has been polished, and diamond is a natural mineral. It is the rough of the diamond. To put it simply, diamond is an elemental crystal composed of carbon that is formed under high pressure and high temperature conditions in the deep part of the earth. It is a symbol of love and loyalty. There are approximately 2.5 billion carats of proven natural diamond reserves in the world. Among them, 650 million carats in Australia and 550 million carats in Zaire. According to the mining level, the existing diamond reserves can only be mined for 25 years, but with the improvement of the level of prospecting technology, new mining areas are discovered every year, and the Canadian diamond reserves have increased significantly in recent years.

Since the diamond mining, a total of about 350 tons of diamonds, that is, 1.75 billion carats, are mined in the world every year in 90 million to 100 million carats, of which gem-quality accounts for the value of gem-quality diamonds, which is equivalent to 80% of the value of industrial-grade diamonds.

THERE ARE FOUR MAIN CRITERIA FOR MEASURING THE QUALITY OF A DIAMOND, NAMELY WEIGHT, CLARITY, COLOUR AND CUT, WHICH IS COMMONLY KNOWN AS THE "4CS". This standard was established by GIA (Gemological Institute of America) and is currently the most mainstream diamond evaluation standard in the world, including China.

Diamonds are evaluated by internationally recognized gemologists and issued by an independent third-party opinion, which is based on the 4Cs and then determines the price of the diamond.

Colorless is best, and the darker the tone, the worse the quality. In the grading of colorless diamonds, the top color is D color, arranged in order to Z, here only the color level from D to J, D-F is colorless level, G-J is near colorless level, from K downwards there is basically no collection meaning, K color below the ring is also very beautiful to make gold. Because the diamond will gradually turn yellow from K downwards, when choosing a diamond, choose the color above H, and the I-J grade is also in the near-colorless range, but a trace of yellowish can also be noticed. Colored diamonds, such as: yellow, green, blue, brown, pink, orange, red, black, purple, etc., belong to the diamond treasures and are expensive. Red diamonds are the most valuable.

Different countries and regions use different color grading systems, and the Gemological Institute of America is divided into 23 grades, which are represented by the letters D-Z. Among them, the 11 levels of D-N are the most commonly used. The European color grading system CIBJO is the representative. China's new national standard in 1996 integrates GIA and CIBJO, which divides colors into 12 levels and uses D-N and N to represent them, as well as percentages and text descriptions.

From the D grade downwards, the price also becomes lower, and the price difference between each color grade is generally 10 to 15 percent, and the price difference between the high color grades is higher than the price difference between the low color grades.

Chongzhen Emperor Zhu Youzhen looked at it for several hours, if he wants to bring it now, it must be to bring the famous treasures that have been discovered in modern times, he is not worried about arousing suspicion because of the similarity, because other people's same treasures will not cause any problems because they find a similar treasure, and the famous treasures are more valuable! Especially if you can have anything to do with politics!

Chongzhen Emperor Zhu Youzhen originally wanted to make a fortune in modern times in this way, but he has always been hesitating, he does not admit defeat, and does not believe that he will not be able to make a difference in modern times if he does not rely on his own ability, he originally wanted to be outstanding in both worlds, but after a long time, his arrogance was almost polished!

Chongzhen Emperor Zhu Youzhen has been in modern times for more than a year, except for studying, there has been no improvement, and he is the same in Daming! In addition to getting a little advanced technology and equipment, the power system in the Beijing-Tianjin area can only be supplied to the Imperial Palace and the Daming Ordnance Manufacturing Bureau.
