Poudretteite
Сyclosilicate mineral
Poudretteite is an extremely rare mineral and gemstone that was first discovered as minute crystals in Mont St. Hilaire, Quebec, Canada, during the 1960s. The mineral was named for the Poudrette family, the owners of the quarry where poudretteite was originally found. Poudretteite is very faintly radioactive.
