No break texture when mining stone

I was doing mining on my minecraft world, and when I came to mine some normal stone (not cobblestone) there was no breaking texture. I thought maybe its on all blocks, but I tried cobblestone and the break texture appeared. Its not a major bug that affects the entire game, but I just thought I would point it out. I was unable to get a picture as it is kind of hard to get a picture when you are mining.
