Diamonds may be forever, but they aren’t what they were. True, they shine just as brightly and they’re as hard as ever, but scientists from the Carnegie Institution of Washington are giving them some competition. An international team led by Carnegie’s Lin Wang have discovered a new substance that is not quite crystalline and not quite non-crystalline, yet is hard enough to dent diamonds.
