Is it true that the price of diamonds is based on a monopoly?
De Beers is the company most cited as the near monopoly. They used to own a massive chunk of the diamond supply and intentionally restricted that supply to increase the price. In recent decades, new sources of diamonds have reduced the De Beers' singular grip. They still have a large share though. Video about this from Adam Ruins Everything: https://www.youtube.com/watch?v=N5kWu1ifBGU it turns out this ancient tradition [of giving diamonds rings for engagements] was invented less than a century ago by the De Beers Diamond Corporation... in 1938, the De Beers Diamond cartel launched a massive ad campaign, claiming that the only way for a real man to show his love is with an expensive hunk of crystallized carbon, and we bought that shit. It continues The only reason diamonds are even expensive is that De Beers has a global monopoly on diamond mining and they artificially restrict the supply, to jack the prices up. Because of this artificial supply restriction, the resale value of diamonds are quite low.
