Analcime is a zeolite mineral with the formula Na(AlSi2O6)·H2O. It typically forms colorless to white crystals that can be transparent to translucent, often displaying a glassy to pearly lustre. Common crystal habits include trapezohedra and pseudo-cubic forms, sometimes as aggregates or as zeolite-rich crystal matrices. Notable specimens have been reported from several classic locales, including in the United States, Italy, and Iran, where well-formed crystals and large aggregates attract attention from mineral collectors.

Guides
All guidesAbout Analcime
Collectors value analcime for its crisp, geometric shapes and its ability to form clear, well-terminated crystals that can be isolated or part of shimmering zeolite matrices. The mineral often occurs in cavities within volcanic rocks and is commonly associated with other zeolites and minerals such as natrolite and stilbite. Size, transparency, and luster influence desirability, with clean, undamaged crystals from notable localities standing out in a cabinet of minerals. Its relative abundance and classic formation make analcime a reliable and approachable addition to many collections.
