A term which refers to slabs which offer mirror images of each other as if opening on the pages of a book. This can be achieved with natural stone whereby two slabs are cut from the same block and the two adjoining faces are finished. Porcelain ‘slabs’ can be used to create this look, the opposite slabs being exactly symmetrical. Bookmatch slabs are always ordered in pairs or multiples of two to achieve the ‘bookmatching’ effect.
