Diamond with not so good C's more likely to break..?

Question

than better ones?

Answer 1

The C's stand for clarity, cut, color, and umm, something else I think.

Color is immaterial to a diamond's strength. Cut is only a factor if it is an unusual cut, the normal cuts are very stable.

Clarity is thought o as a quality factor, but inclusions that affect clarity can weaken it's structure. Are you whacking your diamond with a hammer?

Having a diamond (on a ring, earring, bracelet, etc) break is so rare I have never met anyone to whom it happened.

Answer 2

Then they are not real Diamonds.

Answer 3

nope
