Real-Life Rocks

• Can you melt a diamond?
• Diamond isn't easy to melt, which is why the
  scientists used Sandia's Z machine, the world's
  largest X-ray generator, to subject tiny squares
  of diamond, only a few nanometers thick, to
  pressures more than 10 million times the
  atmosphere's pressure at sea level.
• Can humans make enough heat and pressure to make
  stones?
• Diamond-making machines subject a graphite-carbon
  core at a pressure of 850,000 PSI (pounds per
  square inch) for four days, recreating conditions
  similar to those 100 miles below the earth's
  surface. The lab-grown diamonds that come out are
  optically, chemically and physically identical to
  those that occur in nature.
