$50NL - Does villain have bigger flush?

[Sir Winalot]

Oink oink, all you can eat. Shove river over his raise.

[Janabis]

My concern on the river was that my hand made the worst possible flush, since the only diamonds smaller than mine would make a straight flush. So I went ahead and called, but lost to A2d. But given the size of the pot I suppose there was no avoiding that.
