Pumice is a disordered material, a result of quick freezing of a boiling glass, and is irregular in all directions. It has no preferred cleavage direction, and indeed is not classed as a mineral, for it lacks both a single chemical form, and a defined crystal arrangement.
The pumice with which I'm most familiar is white to light yellow, but depending on the source material, it will be darker as the magma component is increased. Scoria is a more magma-rich form, and is denser than the white variety.
