It forms as a secondary mineral from volcanic activity and is commonly associated with other zeolites like heulandite, apophyllite, and scolecite. Hydrated Framework: Stilbite, like other zeolites, has a unique crystal structure made up of a framework of aluminosilicate tetrahedra, which can trap water molecules and cations (like calcium, sodium). Distinct Crystal Form: Stilbite crystals are usually tabular or sheaf-like, often forming in bundles. Their pearly or vitreous luster gives them a delicate, attractive appearance. Softness and Cleavage: On the Mohs hardness scale, stilbite ranks around 3.5–4, making it relatively soft. It also exhibits perfect cleavage in one direction, which can make it fragile to handle. Water Purification: Stilbite, as part of the zeolite group, is used for water purification. Its porous structure enables it to filter contaminants like heavy metals and ions from water. Ion-Exchange Material: Stilbite can absorb and exchange ions, making it useful in applications like softening water or in industrial catalysis. Heat-Resistant Material: Stilbite’s thermal stability and porous structure make it a subject of study for various high-temperature industrial applications, such as in catalytic converters. Adsorption Properties: Like other zeolites, stilbite is used for its ability to adsorb gases and liquids. This property is useful in the fields of gas separation and storage. Color Variations: Stilbite can vary in color from white, pink, and orange to pale yellow, depending on the trace elements present during its formation. The Deccan Traps are particularly known for producing some of the most aesthetically striking pink and white stilbites. Co-Occurrence in Geodes: Stilbite often forms in geodes alongside other zeolites such as apophyllite and mesolite, making the Deccan Trap region a treasure trove for mineral collectors. Stilbite from the Deccan Traps is not only visually stunning but also scientifically valuable due to its unique properties and applications in fields such as water purification and catalysis.
