Do true marbles vary much in those areas?

Your site is very informative and (http://maplered.com) much appreciated. I realize you
cannot know every Marble (http://www.lightemprador.com) by every sales name but I am considering a
beige Marble (http://www.lightemprador.com) known as tiara beige and (http://maplered.com) wonder if you know anything about
its characteristics? Because it is fairly inexpensive, we wonder if it
is possible that it is of a lower quality, softer, more porous etc.
