Diamond Mystery Solved
The hardest natural substance known to mankind, diamond, is formed when carbon is subjected to extreme temperature and pressure. But what does a diamond itself become when it is put under pressure? Scientists have been trying to answer that question for 40 years—that is, until recently. “It turns out that when enough pressure is applied at the proper angles,” reports The Buffalo News, “the hardest known natural substance turns into graphite, the same carbon . . . from which it is formed.” Scientists say that they hope to use what they have learned through their experiments to make better diamond tools.
