A low-quality 1-carat diamond costs $2000, and up to $20,000 for a high-quality 1-carat diamond, but only because evil corporations like De Beers control the supply of diamonds.
Diamonds are not only sold as useless retarded bling. Diamonds are also very useful in different industries.

De Beers like many other corrupt corporations driven solely by greed are guilty of many crimes like fraud, harassment, murder, etc., solely to increase the wealth of their evil pos shareholders.
But since all economic systems are corrupt, these evil assholes can bribe their way out of any criminal investigations or indictments.
A high-quality 1-carat diamond should cost less than $2.

A mine worker is X-rayed during a diamond check, 1954.
De Beers mine workers were X-rayed at the end of every shift before leaving the diamond mines in Kimberley, South Africa.

Most of them, who survived working in the mines, probably died of cancer caused by the x-rays.
