BulletPoint2 : Stilbite is a common member of the zeolite group, and is found in most of the world's important zeolite deposits. Since its original classification, Stilbite was always regarded as a single mineral species with a slightly variable elemental makeup. BulletPoint3 : In 1997, the Zeolite Subcommittee of the IMA divided this mineral into individual sub-species, thereby regarding Stilbite as a series of two members: StilbiteCa and StilbiteNa. StilbiteCa is the calcium-dominating member, and Stilbite-Na is the sodium-dominating member. Stilbite-Ca is the more common type, and almost all Stilbite in collections are of the Stilbite-Ca type. A distinction between the two Stilbite types is rarely made, and most collectors simply refer to this mineral as Stilbite. BulletPoint4 : Stilbite is named for the Greek word stilbein, which means "to glitter", in reference to the luster of this mineral which is pearly on cleavage surfaces.
