Diamond is just a beautiful stone. According to the income data of domestic residents, people need to spend an average of two months to buy a ring. At most, many friends buy it because they are getting married. Marriage already requires a lot of money. Working overtime every day, braving the cold wind, and going to work for two months in the hot sun every day, only for a stone that has depreciated more than 50% after purchase. Do you think this is wise?
