riferitie

Riferitie is a fictional mineral name used in speculative fiction and hobbyist glossaries to denote an imagined rare mineral with extraordinary optical and physical properties. It is not a mineral name recognized by the International Mineralogical Association or by standard mineral databases.

In world-building contexts, riferitie is described as a translucent to iridescent crystal with a high refractive index and pronounced birefringence. Descriptions vary, but it is often said to form in extreme environments such as deep-sea hydrothermal systems, subduction-zone metamorphism, or meteorite impacts. Some accounts attribute luminescent behavior under ultraviolet light and unusual chemical stability.

Because it is fictional, there are no verified specimens or natural localities for riferitie. The term appears mainly as a plot device or world-building placeholder in science fiction and speculative non-fiction glossaries, where it is clearly labeled as fictitious to avoid confusion with real minerals.
