Diamond n Graphite?

Question

Why is diamond rarer in nature than graphite?Is it because of its structure or anything else.

Answer 1

may b bcoz of the crystal structure and the conditions causing the structural change. TEMPERATURE AND PRESSURE

Answer 2

Diamonds are actually graphite stones that have been put under enormous pressure and temperature for a long time. That's why the diamonds are a rare thing.

Also, some diamonds are of space origin. Like those that come from Namib desert. It is believed by scientists that the field there appeared as a result of a meteorite crash. That makes them a still more rare thing on Earth.

Answer 3

Yes, the structure of diamond doesn't form under normal conditions.  You need intense heat and pressure to create the crystal lattice.

Diamond forms deep within the mantle at around 400,000 psi and over 2,000 degrees F.  Graphite can form just about anywhere when something containing carbon is burned.

Answer 4

ya diamond is a octahedral structure whereas graphite is hexagonal structure...hence itn takes long long days to form...eventhough both of them are pure form of carbon

Answer 5

Diamond is rare because of the conditions required for its formation.  it requires very high pressures and temperatures. It is not stabe at surface or shallow crustal conditions.  

Also, diamond must be brought rapidly to the surface from where it is formed if it is not to re-equilibrate and revert to graphite.  These conditions are only met in very special circumstances.
