Wollastonite is a calcium silicate mineral that forms in contact metamorphic and skarn environments, typically presenting as white to pale pink crystals or fibrous, satin-like masses. It often occurs as slender, acicular aggregates or columnar to granular aggregates with a vitreous to silky lustre. Notable specimens have come from classic skarn districts in the United States, Canada, Madagascar and Afghanistan, where hydrothermal fluids and rapid crystallization promote clean, sharp crystals and attractive luster.

About Wollastonite

Collectors prize wollastonite for its bright, uncolored to subtly colored crystals, clean cleavage, and the way it can form striking needle-like or radiating crystal groups. In hand specimens, its white to pale ivory tones contrast well with associated minerals such as calcite, garnet, or diopside, highlighting texture and habit. While not as widely sought as some dimorphic silicates, finely formed wollastonite from renowned localities remains a welcome addition to mineral cabinets for display and study.
