First, the reason why diamonds were bought well at first was the advertising effect, because diamonds had no practical value and the demand was small. As a result, diamond dealer De Beers had to cut 90% production. In order to impress the world's demand for diamonds, he played? Are diamonds eternal? Classic slogan. It is precisely because this advertisement touched the hearts of many women that diamonds have such a high price.
Second, the appreciation space of diamonds bought by ordinary people is basically equal to 0. We ordinary people can't afford extra-large diamonds, nor can we afford extra-large diamonds, let alone very famous diamonds. So the diamonds we buy are diamonds that have no room for appreciation at all. If we take it back to the jewelry store for recycling after buying it, we may only receive the previous price110, and even this price is for the metal with diamonds, not diamonds.
Third, ordinary people buy diamonds only for marriage. Ordinary people buy diamonds because when they get married, the woman is like a diamond ring. Want one? An eternal one? Marriage. But there is absolutely no need to spend this money. If you spend it on other things, buying some gold jewelry will be more fragrant.
