De Beers is concerned about the flooding of the market with synthetic diamonds, which, according to the company, could undermine the sustainable development of the industry in the long term.
De Beers Director for Strategy and Corporate Affairs, Bruce Cleaver, said that "inferior" stones could also have a negative impact on profits, APA reports.
He added that synthetic diamonds may prove even more dangerous if their producers do not put market participants in the knowledge that the stones were created in the laboratory.
"Manufacturers are able to create diamonds, but we continue to explain to customers how to distinguish an artificial stone from the real one," Cleaver said.
De Beers controls more than 30% of the world diamond market, the total value of which is estimated at $ 14 billion.
According to APA, the synthetic stone market is estimated at $ 9 billion.
