    Natural diamond grows predominantly in an octahedral form that provides several sharp points optimal for single point diamond tools. It also occurs in a long stone form, created by the partial dissolution of the octahedral form, used in dressing tools such as the Fliesen ® blade developed by Ernst Winter & Son. Long stone shapes are also produced by crushing and ball milling diamond fragments.
