Answer
I have heard of this happening when a diamond has a flaw in it. A jeweler will be able to let you know about diamond flaws.
Answer
Yes - A diamond can chip or fracture irrespective of flaws.
While diamonds are quite hard (scratch resistant), they all have 'fracture planes' as a result of how the carbon atoms are ordered, and thus their toughness (resistance to fracture or chipping) is good but not great. You can smash a diamond with a hammer for example.
I know several diamond cutters who do the bulk of their work recutting chipped diamonds, so it happens far more often than people would think.
