When force is applied to a material like steel, the atoms can shift around due to its flexible structure, and the impact is absorbed, as opposed to shattering the steel. Due to the lack of flexibility in a diamonds structure, a strong impact can break the stone.

Answer 2

Explanation:

Yes, even though a diamond is the hardest naturally occurring substance, it can be broken with a hammer. Diamond are susceptible to chipping or fracturing from impact. If conditions are just right, they may even break apart along their cleavage lines.
