Cleopatra Granite in Kitchen

Thank you for the great information on your website.  I wish I had seen it
before we insalled the Granite (http://tanbrown.org) in our kitchen.  We installed Cleopatra in
our kitchen about 1 year ago.  We have found it to be very absorbent.  Water
glasses leave a dark ring but then go away over time.  The Granite (http://tanbrown.org) hasn't
stained but it is getting darker where I frequently cook.  I did the lemon
test on a scrap piece and (http://maplered.com) it got dark right away.  It did not however get
dull.  I see from your website that you sell the Cleopatra so I'm hoping you
can tell me what to do to prevent it from discoloring.  I'm afraid this is
one of those Stone (http://g603.net) s you would never put in a kitchen.  Please help.
Thanks you!  Jennifer
