In front of Chen Shiliang, 25, is a high-speed rotating cast iron disc coated with diamond powder. In his left hand, he held a "hall" with a diamond (a special fixture), and his right hand was a 14-fold magnifying glass that was not put down for a moment. The look of the mill is focused on the mill. The "hall" of the left hand just leaves the disc and leaves. The particles are drawn with a silver arc... How is the diamond cut? It has not been known to outsiders... Reporter Walk into the mysterious diamond world of Panyu Shawan and witness the production process of diamonds at close range. This is a quiet factory in Panyu Shawan Jewelry Industrial Park. The entire industrial park is very secluded, but there are tens of thousands of skilled diamond cutters, most of them only in their 20s. In the world diamond industry, this group of young boys and girls who seem to be inconspicuous has a very respected title - the combination of Chinese workers, advanced technology and the skilled craftsmanship of skilled workers, making Panyu's diamond processing industry a global A model of cost effectiveness. Diamond cutting technicians give diamonds new diamonds Uncut diamonds are like ordinary gravel, without the brilliance of light, only diamond cutting technicians can give diamonds a second life. The Miqi Diamond Cutting Workshop at Panyu Shawan Jewelry Industrial Park is one of the mysterious diamond cutting workshops. The workshop is a completely enclosed space, air-conditioned, and you must punch in and out. The stone classification is the first process, and the purity of the original stone is determined by a magnifying glass to be initially graded. Most of them are done by female technicians. Before the eyes are filled with diamonds that are as ordinary as a hill, use a pair of tweezers to pick up a piece of rice-sized stone, and use a single-hole magnifying glass to observe it. According to the grade, use the tweezers to accurately throw it into the corresponding paper bag and pull it up in the air. Beautiful arc. “It’s a test for girls to repeat the same action for a long time. Only girls have such patience.†The selected diamonds should be designed to maintain the maximum weight and minimize impurities. The rest of the work is cutting and polishing. Cutting is now generally done with a laser, which is much more advanced than the traditional method. The most tested technique is grinding. Hundreds of cutters sit side by side in front of a high-speed rotating wheel, and the clamping lever in the handle gently touches the grinding disc, diamond and grinding disc. The silver arc is constantly shining. In the diamond workshop, the friction between the disc and the diamond is removed, the diamond sorting sound, and the tens of millions of dollars of diamonds are passed between them, and no one speaks. Improperly cut diamonds with diamonds will "explode" Diamonds are already the hardest substance in the world. What to cut and polish? “Just diamonds are used to grind diamonds.†Zhu Boyuan, production manager of Miqi Diamonds, said that diamonds will be twisted into two or more pieces along the grain direction as needed. If you don't find the texture, the laser is refracted inside the diamond. It is possible to form a focus point where you don't need it. The heat generated can easily change the internal pressure of the crystal in the diamond structure. If you encounter weakness in the structure, it is likely to Cracking during cutting. The cut diamonds must first be "rounded" by grinding all the petals (facets) on a cast iron disc coated with diamond powder and lubricating oil to give the diamond an attractive brilliance. Due to the slightly different hardness of the diamond in all directions, it is necessary to rely on experience when grinding. China's diamond cutter technology is world-class. Diamonds have 4C. Colour, Clarity and Carat are all natural. Only cutting is the key to determining the final value of diamonds. Now "Chinese workers" are gradually becoming synonymous with good craftsmanship and quality. Chen Shiliang, a 25-year-old Henan young man who has been in business for eight years, is a world-class diamond cutter in the eyes of his Belgian boss. In this Belgian diamond company with more than 300 cutters, almost all Chinese workers. In the past, Panyu's diamond processing was mainly based on small and medium-sized sawn and granular drills, and a small number of large rough diamonds. The diamond is small in size, high in hardness and high in value. It needs fine cutting and grinding during processing to reduce unnecessary loss as much as possible, and it has high requirements for all aspects of the practitioners. The cost of cutting and polishing 1 carat of diamonds in China is about $17.80 in China, and almost eighty-nine times more expensive in Belgium. China is the second largest processing country for small and medium-sized diamonds in the world. According to reports, there are more than 400 jewelry processing enterprises and 100,000 employees in Panyu. The product advantages are mainly concentrated on diamond blank processing and jewelry inlay business. It accounts for 1/3 of Guangdong Province, and the total import and export volume accounts for 24% of the country. In 2010, the annual export value of Panyu jewelry was 1.995 billion US dollars. China is already the second largest processing country for small and medium-sized diamonds in the world. At present, 70% of Hong Kong's jewellery is produced and processed in Panyu, and Hong Kong is one of the most important jewellery centers in the world. Antwerp is the world's diamond center. Mainland China (mainly Panyu) and Hong Kong are the exporters of 25% of the finished diamonds in Antwerp.
