Reeglite

Reeglite is not a mineral recognized in major mineralogical references. The term is used in informal discussions and some works of speculative fiction as a fictional mineral or a placeholder name for a hypothetical species; there is no standardized composition or set of properties.

In fictional contexts, Reeglite is often described as a crystalline mineral with a distinctive color and habit; descriptions vary, with properties assigned by the author—color from blue to violet, hardness around 5 to 7 on the Mohs scale, and occasional luminescent or anisotropic optical effects.

There are no verified natural occurrences. No specimen or locality is documented in major mineral databases; the term does not appear in peer‑reviewed mineralogy literature.

Etymology and naming: The name Reeglite appears to be a coinage, with no universally accepted etymology or official naming history.

As a result, Reeglite is primarily of interest to students and readers as a case study in fictional minerals and in exercises on mineral nomenclature rather than as a geological object.
