Catapleiite
Mineral
Catapleiite (Na2ZrSi3O9·2H2O) is a dimorph of gaidonnayite rarely found by itself. Its name derives from the Greek words "κατα" (kata) and "πλειον" (pleion) meaning "with more" as it is mostly accompanied by a number of rare minerals. When pure it is colorless, but it is most often seen as a tan, brownish-red, light yellow, dark brown, flesh red or orangish in color. It is mostly found on Låven Island, Norway. Its hardness on the Mohs scale is around 5.5-6. It has a monoclinic crystal system.
