Name:Named in 1867 by Charles U. Shepard. A similar material, from the same occurrence as cymatolite (boulders on the Barrus Farm, Goshen, Massachusetts), was named Aglaite by A. Julien in 1877, but cymatolite has precedence and is the common name used today. Cymatolite was originally listed as a variety equivalent to Pihlite.
