The Diamonds Suck website is the perfect antitode to the news that the Diamond industry has successfully halted the plunge in the fundamentally worthless stones' retail price.
I saw that as well, but I think cut hardness must be jewelers terminology. As far as actual hardness diamonds are a 10 on the mohs scale, moissanite is a 9.25, and tungsten carbide is usually around 9-9.5.
While I agree we shouldn’t be using them for jewelry, diamonds are factually very important and incredibly valuable to manufacturing.
They’re the only thing hard enough to cut and shape tungsten carbide, which is instrumental in basically any complex machinery work.
Interestingly, moissanite (per the source referenced by the article) exceed diamonds in hardness (“toughness”) as well.
