Major poems in the book include Geodes and Diamonds.
Bök explains the title in an introduction. Crystallography refers to both the science of crystallography and a reanalysis of the word's roots: crystal meaning "clear", and "graph" meaning "writing".
Inspired by the etymology of the word “crystallography,” such a work represents an act of lucid writing, which uses the language of geological science to misread the poetics of rhetorical language. Such lucid writing does not concern itself with the transparent transmission of a message (so that, ironically, the poetry often seems “opaque”); instead, lucid writing concerns itself with the exploratory examination of its own pattern (in a manner reminiscent of lucid dreaming).
