Meionite is a tectosilicate in the aluminosilicate framework, typically forming colorless to brown, green, or violet crystals with a vitreous to resinous lustre. It commonly occurs in fibrous, granular, or massive habits and can exhibit a conchoidal fracture with a distinct cleavage. Under ultraviolet light, meionite displays fluorescence in white, red, and yellow hues, making it a striking specimen for display and study.

About Meionite

Significant specimens have been reported from the United States and Namibia, where meionite occurs in environments associated with metamorphic and hydrothermal activity. Collectors prize the mineral for its delicate crystal forms and its fluorescence, which adds visual interest under UV illumination. The combination of its tetragonal crystal system, moderate hardness, and transparent to translucent transparency contributes to its appeal as a mineral specimen suitable for cabinet displays and educational purposes.
