tulitte

Tulitte is a fictional mineral described in worldbuilding, speculative fiction, and role-playing settings. It is commonly depicted as a rare silicate with distinctive luminescent properties and a violet color range.

Etymology and classification: The name tulitte is typically linked to a fictional region or culture, such as the Tulit Mountains. In most renderings, tulitte is described as a layered silicate with a sheet-like crystal habit, though exact chemical composition varies by author.

Physical properties: Tulitte crystals are usually tabular to prismatic, with a vitreous luster. They range in color from pale lavender to deep violet and exhibit strong luminescence under ultraviolet light. Mohs hardness is commonly placed around 6, and the typical specific gravity is about 3.2. Cleavage is described as imperfect in one direction, with conchoidal fracture in other directions.

Occurrence and formation: In fictional lore, tulitte forms in high-temperature metamorphic environments or within pegmatitic pockets where hydrothermal fluids interact with aluminosilicate minerals. It is often described as occurring in association with other invented minerals in the same geological setting.

Uses and cultural significance: Because of its glow, tulitte is prized as a gemstone substitute in jewelry for its color and luminescence. In some technoscience-flavored settings, tulitte is imagined to have photoluminescent or optoelectronic properties, though no real-world application exists.

Limitations: There is no verified occurrence of tulitte in the real world; tulitte remains a construct used for fictional worldbuilding and entertainment.
