The diamond mall per carat is the assured mall designated by China Jianbao Association, and also the resident mall of the National Jewelry and Jade Testing Center and the National Quality Testing Center, which can definitely guarantee the quality of the goods sold in the mall. At the same time, the styles and categories of diamond ornaments in shopping malls are extremely rich, about 20 times more than those in traditional department stores. The shopping mall has also set up a personalized customization area, which can completely customize private styles according to consumers' wishes. In addition, each carat diamond jewelry store directly accepts bare stones from suppliers and processes them separately, so it doesn't need to pay expensive deduction points like traditional diamond jewelry sales in department stores, so the price of diamond jewelry in each carat diamond jewelry store will be 50% lower than the market price, that is, a diamond ring of 1 10,000 yuan, and only 5,000 yuan will be sold in each carat diamond jewelry store.
