Name:
Named in 1797 by Jean-Claude de la Métherie from Greek στιλβη "stilbein", to glitter of shine, or "stilbe", a mirror, alluding to its pearly or vitreous luster. Originally, but inconsistently called zeolite in 1756 by Axel Cronstedt. Named crystalii ad centrum tendentes in 1758 by Cronstedt. In 1772, Johan Gottschalk Wallerius called this mineral zeolite selenitica lamellaris. Also in 1797, de la Métherie called this mineral zeolite nacrée. Werner (1780) called this mineral strehliger zeolith. René Just Haüy (1801) used the term stilbite anamorphique for a mineral now recognized as heulandite. Desmine was introduced in 1818 by Johann Friedrich August Breithaupt. Sphaerostilbite was used in 1832 by François Sulpice Beudant. Additional varietal names and synonyms have been proposed: blättricher zeolit, hypostilbite, puflerite, radiated zeolite, and syhedrite.
This name now refers to the zeolite subgroup including the Barrerite - Stilbite-Ca - Stilbite-Na - stellerite series.

The end members barrerite and stellerite are orthorhombic and the others monoclinic, but the differences are subtle and difficult to pick by XRD and so the species need to be confirmed by a reliable chemical analysis. Crystals of this group are usually also chemically zoned.

Prehnite and the Heulandite subgroup may also show a similar habit.
