We have had this lamp for a number of years and have loved it.  However, about two years ago, the base began to develop a horrible crack that runs around the bottom third.  The lamp has never been dropped or hit - nothing.  Needless to say, we were amazed when this happened.  We did not know what to do, after having owned it for awhile.  Still love the shade and have had many compliments on it.  The base, however, looks pathetic with the crack.
