To synthesize the crystals, the team compressed highly ordered pyrolytic graphite to pressures as high as 20 gigapascals, roughly 200,000 times the atmospheric pressure at Earth’s surface.

Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder.
