Scolecite is a tectosilicate mineral and a variety of the zeolite group. It was first described in 1813 as a distinct mineral named in Greek word as “skolex” meaning worm. The name refers to the tendency of the mineral’s ability to form worm-like aggregates.
Scolecite can be seen in volcanic rocks, particularly basalts and andesites, where it forms as a secondary mineral.
It is most commonly found in India, in the Deccan Traps region and also occurs in Iceland, the Faeroe Islands, Canada, and the United States.
Scolecite has limited commercial uses. It has been used rarely as a gem material and shown in using scolecite as a catalyst or for water softening. For the most part, scolecite is primarily of interest to mineral collectors.

Scolecite is a hydrous calcium aluminosilicate mineral which crystallizes in the monoclinic crystal system with a Mohs hardness of 5-6. Scolecite is typically white or colorless, with a vitreous luster. It has perfect cleavage in one direction.
Scolecite is considered a relatively uncommon mineral. Well-crystallized specimens can be of interest to mineral collectors, but does not have a significant global market or value outside of the collector community.
Prices for scolecite specimens tend to be modest, typically ranging from a few dollars to a few hundred dollars depending on the quality and size of the sample. Scolecite has a niche market appeal primarily among mineralogists and hobbyists.
Generally, scolecite is a zeolite mineral with limited commercial applications, but it retains some interest among mineral collectors due to its rarity and distinctive appearance.
Its global value and market presence are relatively small compared to many other minerals.
