Many people buy diamonds when they want to propose to their lovers, and diamonds have become a symbol of love. However, since the price of natural diamonds is always too high for ordinary people, the rhinestone market has become robust in recent years. The sales of rhinestones now have increased by more than 60 percent than its sales in 2021.

Nearly half of the world's cultivated diamonds are produced in China, with 80 percent of the production coming from Central China's Henan Province.

Given the main composition of diamonds is carbon, which is also the composition of black graphite, scientists got the idea to artificially transform the cheap and plentiful graphite into shiny, expensive diamonds. There seems to be no difference between natural diamonds and artificial ones from a naked eye, but the price of rhinestones is only one-third of the price of natural diamonds. 

Now Henan has mastered the superior, refined and advanced technology of "turning dust into gold," breaking down the international technological monopoly. Other than making jewelry, different kinds of diamonds are used in many important areas, including aerospace semiconductors, as well as coal and carbon mining. Netizens are marveled at the advanced technology that Henan has mastered.
