This is an example of Fairyland Lustre china in the Z5158 pattern, as marked on the bottom of the piece. Some people can misread the mark as just 5158 or they think the Z is a 2 and read it as 25158. Please remember that the picture above is just one example of a Wedgwood fairyland lustre piece from the Z5158 pattern number. What you have could look significantly different. Your piece will also be marked with the Portland vase, followed by Wedgwood England or Wedgwood Made In England.
