Heulandite
Heulandite is quite a common mineral, but not a particularly popular one. It is part of the Zeolite group of minerals and can occur in several colours including green, pink, yellow, and white.
It is pretty much only used as a mineral specimen, with some pieces showing very nice crystal formations.

Information about Heulandite
Heulandite is a series of zeolite group minerals which refers to five similar minerals – Heulandite-Ba, Heulandite-Ca, Heulandite-K, Heulandite-Na, Heulandite-Sr.
Heulandite-Ca is the most common of these minerals – however, it is common for minerals that have not been lab analysed to simply be described as Heulandite.
Heulandite often occurs alongside other zeolite group minerals, including stilbite.
Uses and History
Heulandite is primarily a collectors mineral and decorative stone.
Heulandite was named in 1822 by Henry James Brooke in honour of Johann Heinrich Heuland, a mineral collector and dealer.
In 1997 the mineral was divided into its individual sub species by its chemical composition.
Mineralogy
colourless, yellow, white, pink, pale pink, peach
Hazards and Warnings
Mineral collectors should wash their hands after handling specimens, to avoid any exposure to potential toxins.
Almost all rocks, minerals (and, frankly, almost all other substances on earth) can produce toxic dust when cutting, which can cause serious respiratory conditions including silicosis.
When cutting or polishing rocks, minerals, shells, etc, all work should be done wet to minimise the dust, and a suitable respirator or extraction system should be used.
