Images of Mesolite

Mesolite is such a cool looking gem.  It looks like a crystal puff ball!  Mesolite has long, slender crystals the radiate out in all directions.It generally forms as radiating masses of slender crystals, but sometimes it will also form as compact masses or fibrous stalactites. Mesolite is a rather widespread stone being found in cavities in Basalt and Andesite, as well as, in hydrothermal veins.  Some of the best specimens are found in India, the Czech Republic ,Antarctica, the Faroe Islands, and in the states of Washington, Colorado, and Oregon.
