THOMSONITE SPECIMENS

Thompsonite is a relatively rare mineral belonging to the zeolite group, known for its striking radiating needle-like crystal formations. It typically forms in shades of white, pink, yellow, or even pale green, with a soft pearly luster that adds to its appeal among mineral collectors. Thompsonite can be found in botryoidal (grape-like) clusters or as radiating sprays, often filling cavities in volcanic rocks like basalt. This mineral is primarily composed of calcium, sodium, aluminum, and silicate, and it's noted for its ability to absorb water, a characteristic trait of zeolites.
