leverite

leverite n. (also leaverite) a worthless stone or rock, especially one mistaken as being valuable. Editorial Note: Paul Dickson writes in Family Words (1998, p. 79), “Heaverite, according to Raymond J. Nelson of Cody, Wyoming, is a rock that, upon examination, is only good to ’heave ‘er right now.’ Geologist Davide Dattie of Spring Valley, Minnesota, reports Nebulite is a rock you cannot identify—a rock of unknown or nebulous origin.” Etymological Note: As explained in the citations, “leverite” is a jocular transformation of “leaver ‘er right (there).” The -ite suffix is used to form the names of minerals and of organisms found in fossils, among other things.
