translucent crystal

Scolecite from Teigarhorn, one of the most famous zeolite locations in the country.

Scolecite forms as sprays of prismatic needles, with large deposits in Iceland.  The crystals will curl when exposed to intense heat which is how it came to be named for the Greek word for worm.

Teigarhorn is a natural monument and nature preserve in the eastern part of Iceland.
