Is De Beers still a monopoly?

No, De Beers is not still a monopoly. Although the South African jewelry maker is still one of the leading suppliers and jewelry houses in the world, it has not been able to largely control diamond prices since the early 2000s due to changes in the market. The shift occurred largely due to an influx of new, smaller suppliers located outside of South Africa. Shop a diverse assortment of De Beers diamond jewelry on 1stDibs.
