Quartzite

With a quartz sandstone, it is easier to break around the grains than through them. This quartzite sample shows the cross-bedding that is preserved in some quartzites. The cross-bedding was created when it was soft sandy sediment, preserved when it was turned to a hard sandstone, and still preserved when it was metamorphosed into quartzite.
