Question

Can diamond be destroyed with atom bomb?

Answer 1

Diamond burns just like charcoal because it is the same stuff, actually this is how diamond was proved to be carbon.

Answer 2

Even diamond has a melting point that is far below the temperatures reached in an atomic blast.  

Yes, it would melt and boil away in a fraction of a second.

I guess you were really thinking would the blast shatter it, and hence you are probably confused.  Diamond is the hardest substance, but that does not mean it can't be shattered.  People shape diamonds, so I am sure an atomic blast could fragment a diamond, but firstly it would be obliterated by the heat.
