I'm sure what I have is sandstone, not granite. Hard enough that it won't crumble in your hands, but softer than, say, a brick, I think. About the same color as red brick (but then, I suppose brick isn't always the same color, is it?). The building I salvaged it from was mostly brick but with a few bits in stone. The demolition company apparently wasn't making any effort to save the stone. Most of it was broken, heaped together with the brick, even those pieces with ornamental carving. That's why I felt OK "liberating" a few chunks.
