TPNK+GS raised on the turn

[thesharpie]

Button recently raised me on the turn when a 3rd flush card fell, I folded and he showed a flopped set. He does seem tricky though, he defended his blind against a button open raise, led 3 bet the flop with a flush draw, check called a blank turn, and check raised the river representing a straight with just a busted draw. UTG in this hand is aggressive preflop and pretty aggressive postflop. He could be calling with a wide range of hands. Do you call the river? If he was on a flush draw a spade draw seems more likely, he probably would've raised the diamond draw on the flop.
