First: from the composition of diamonds, worthless diamonds are actually diamonds, which are mainly composed of carbon. In terms of composition, it is no different from graphite. Diamonds can be produced by chemical methods, which means diamonds can also be produced, so diamonds are not scarce in quantity. Generally, the rarer the jewelry with limited reserves, the more valuable it is. Take gold and silver as an example, its reserves are limited, so it can't be produced and can only be purified, so the value of gold and silver is higher than that of diamonds.
Second: the reserves of diamonds are very large. Even without artificial diamonds, the reserves of natural diamonds are very rich. If you follow? Things are rare? In principle, the value of diamonds is definitely not that high. Moreover, due to the limited reserves of diamonds, it is impossible to buy diamonds unless they are very large carats. If ordinary people buy a diamond ring with 50 cents or 1 carat and want to invest, they will definitely lose money.
It is precisely because of the large reserves of diamonds that a large number of natural diamonds have been dug up, so if you want to recycle diamonds after purchase, you basically need to discount them. Now the price of diamonds on the market is already very high, but from the perspective of investment return, buying gold and silver is not cost-effective, so diamonds are completely IQ tax.
Third: the essence of the merchant's gimmick diamond is diamond, and the biggest feature of diamond is its high hardness. Moreover, things with high hardness are definitely rarely broken and damaged. So in order to give diamonds higher commercial value, do merchants have it? An eternal one? A stunt show. When diamonds are associated with love, many people hope that their love will last for a long time, and diamonds are just indestructible and hard things. So businesses take advantage of this.
It is a good idea to link diamonds with love and let consumers compete to buy diamond rings. When you fall in love and get married, you will buy a diamond ring. But in fact diamonds have nothing to do with love. This is just a gimmick that merchants want to promote. However, we have to admit that this kind of marketing is successful. Up to now, people still believe that diamonds are associated with love. I hope my love can be as eternal as a diamond.
As long as consumers believe in the meaning behind diamonds, even if diamonds are worthless, some people are willing to pay the bill and can sell them at sky-high prices.
