I'm assuming what you're thinking is that no single diamond is going to pay you off on the end here, unless you get lucky and he has Jx-Xd. So the only hands that call a push here have you beat. Which is probably right.

I dunno though. Not much has you beat here. And especially not much has you beat here that would risk a check through on the river in the event that you were on a(n aggressively played) diamond draw. I think I bet it. Which of course is a push here.

I think it's close.

edit: oh, i forgot to mention: why the call on the flop? were you thinking that you wouldn't be able to push him off a diamond regardless, so you may as well wait for a blank turn to fire out on? just wondering what your thought process was.
