The proper environment for diamond formation includes the right temperature, pressure and what else?

• A. Availability of water
• B. Availability of carbon
• C. Oxygen content
• D. Magnetic field strength

Answer: (B)

The key idea is that a carbon source must be available. Diamonds are made from carbon atoms arranged into a strong lattice, so even with the right high temperature and pressure, you need carbon to actually form the crystal. If carbon isn’t present, no diamond can form. Water isn’t required as a driving ingredient for diamond growth, though it can influence other mineral processes. Oxygen content isn’t a deciding factor for diamond formation, since carbon is the essential building block. Magnetic field strength doesn’t play a role in the crystallization of diamond under mantle conditions. So the presence of carbon is the missing piece that completes the environment for diamond formation.
