Tiinquartz

Tiinquartz is a fictional mineral described in science fiction and fantasy literature as a titanium-rich variety of quartz. The name combines the chemical symbol Ti with quartz, reflecting its imagined origin and appearance. In its standard in-world presentation, Tiinquartz is valued for its color-shifting sheen and perceived energy properties rather than for any real-world mineralogical status.

Purported properties include a hardness near 7 on the Mohs scale, a vitreous luster, and a color range from pale silver-blue to amber and violet, often with an iridescent or cat's-eye effect produced by nanoscale titanium-rich inclusions. The refractive index is typically cited around 1.54–1.55, with crystals described as prismatic or tabular in form, and a specific gravity similar to basaltic quartz assemblages. In fiction, surface patterns such as asterism or adularescence may be attributed to layered Ti-rich nanostructures.

According to its fictional lore, Tiinquartz forms in hydrothermal veins and pegmatites where titanium-bearing fluids interact with silica-rich rocks. Color and optical effects are said to depend on trace elements and radiation exposure within the setting. It is often depicted as occurring alongside titanium minerals such as ilmenite or titanite.

Uses within stories typically include Tiinquartz as a gemstone in jewelry, a component in ceremonial regalia, or a power conduit in advanced technologies. In fictional economies, its rarity and aesthetic appeal drive trade, and it may be subjected to heat treatment or irradiation to stabilize color.

Note: Tiinquartz is not recognized as a real mineral by major geological authorities. It exists as a literary and entertainment concept used to enrich world-building.
