Since the time immemorial, shiny objects like gold and diamond have attracted humans.
In fact, many wars have been fought over these precious objects.
After a long wait of nearly 80 years, engineers have finally succeeded in converting hydrogen into metal.
The team came up with some ideas about what might be causing the diamonds to fail and corrected them.
One possibility was surface defects, so they etched all diamonds down by five microns to eliminate these.
Another problem may be that hydrogen under pressure could be forced into the diamond itself, weakening it.
So they cooled the hydrogen to slow diffusion and added material to the anvil that absorbed free hydrogen.
