Nowadays, the gold investment products made by investors, such as T+D in Shanghai and paper gold in banks, are mostly the original price of gold mines.
After the gold mine is mined, it is thrown into a melting furnace to extract gold bars, which are cut and made into jewelry by craftsmen.
Mining fee, smelting fee and craftsman's manual fee are added in the middle, so the price difference will be above 100.
The cost of each jewelry counter is different. For example, the cost of jewelry stores in Liu Fu is slightly lower, because most jewelry is recycled gold, so gold jewelry in Liu Fu will be cheaper than other counters;
Chow Tai Fook and Zhou Shengsheng cut gold bars to make jewelry, and the cost is slightly higher, so the price of jewelry counters is also a little more expensive.
