Diamond is the hardest. Diamond can cut from glass to steel. The Lawrence Livermore National Lab (LLNL) revealed that diamond can be stronger. The rapid compression process makes diamond even stronger than we thought.
The diamond can withstand nearly million times of atmosphere pressure before being crushed. The university of Rochester showed even powerful lasers could not disturb the diamond. The diamonds are formed under 87 to 120 miles under the earth’s mantle at a high temperature and pressure.
The diamond is formed by carbon containing minerals deep under from 1 billion to 3.3 billion years. The research found the behavior of natural diamond by subjecting it to high shock waves. The diamond shows considerable strength before the diamond melted. Around six million atmospheres of pressure the diamond melts itself.
