Diamonds take millions of years to form within the Earth's mantle, but now scientists are trying to produce them synthetically.
- Diamonds take a long time to form in the Earth's mantle.
- Made only of carbon scientists have tried to produce them in the lab.
- The HTHP process, simulates high temperature, high pressure found in the Earth's mantle to produce small diamonds.
- The CVD, Chemical Vapor Deposition method, is a more successful method. It uses diamond 'seeds', hydrogen and methane to produce carbon atoms that latch on to the seed.
Diamonds are forever, or more precisely they take a long time to form deep within the Earth's mantle.
But as diamond is just carbon, scientists have been working for years to find a way to recreate nature's most beautiful mineral.
Diamonds have been created in labs using the HPHT method.
HPHT – High ...
