Globally, thomsonite is one of the rarer zeolites. Thomsonite was first identified in material from Scotland in 1820. It is named for the Scottish chemist Thomas Thomson. The crystal system of thomsonite is orthorhombic. The Mohs hardness is 5 to 5.5. It is transparent to translucent and has a density of 2.3 to 2.4.

Thomsonite is a hydrous calcium sodium aluminum silicate member of the zeolite family that crystallizes in the form of spherical concretions, layered aggregates, and slender needle-like prismatic crystals. The color of Thomsonite can range from orange, pink, yellow, and white, to even green and brown!

Thomsonite is a mineral belonging to the zeolite group of minerals, which has over 35 different recognized members. Thomsonite is one of the rarer zeolites. It forms tight acicular radiating clusters and sphericules as well as some blockier crystals and is found in the vesicles or bubbles of volcanic rock, as are most other zeolites.
