Meerschaum

Hard to say. The carvers seem to be quite good at squeezing the most out of the stone they have available and as such, might from time to time, create some pretty short (in depth) pipes or, conversely, some short in length but condiderable in depth pipes based on the stone.

Bottom line though is if it doesn't look right to you, you'll not be happy with it. It is more important to select a pipe that you LIKE than to settle for one because that is what is available. Know what I mean? You want to like it enough that you'll smoke it regularly, not resent; thereby relegating it to collecting dust instead of collecting color.
