quartzis

Quartzis is a term that appears in speculative fiction and theoretical mineralogy to denote a crystalline form of silica with distinctive properties. It is not an officially recognized mineral species by the International Mineralogical Association, but is used by some authors and researchers to explore alternative mineralogical possibilities.

Composition and structure: quartzis is described as primarily silicon dioxide (SiO2) with trace dopants of metals such as aluminum, titanium, or chromium. It is said to crystallize in a hexagonal system with a quartz-like framework, giving it a hexagonal prismatic habit similar to quartz. Typical descriptions assign a hardness around 7 on the Mohs scale and a refractive index close to that of common quartz, though dopants may alter color and translucency.

Formation and occurrence: in fictional contexts, quartzis forms in high-temperature, high-pressure environments within hydrothermal systems or arises synthetically in laboratory conditions that mimic geological processes. Real-world analogs include natural quartz varieties and laboratory-grown synthetic quartz used in electronics and optics, which sometimes inspire the fictional material.

Uses and significance: in stories, quartzis may be depicted as a material for energy storage, precision optics, or jewelry, valued for its color variability and stable crystal lattice. In practical terms, the concept echoes the real versatility of silica-based materials and the role of dopants in tuning optical and electronic properties.
