ciocrlia

Ciocrlia is a fictional mineral species described in speculative geology and worldbuilding. It is typically presented as a blue‑green silicate mineral with a vitreous luster and a hexagonal crystal habit, used in various fantasy and science fiction settings to illustrate mineral diversity and geological processes.

Physical properties commonly attributed to ciocrlia include translucent to transparent crystals ranging in color from azure to teal. In worldbuilding references, its Mohs hardness is often placed around 6.5, with a refractive index near 1.62 to 1.66 and a specific gravity in the vicinity of 3.2 to 3.4. Crystals are described as forming in short, prismatic habits, occasionally appearing as tabular forms within hydrothermal veins.

Occurrence and formation narratives place ciocrlia in late‑stage hydrothermal systems within volcanic host rocks such as andesite or rhyolite, at temperatures roughly between 300 and 450 degrees Celsius. Its coloration is typically linked to trace cobalt and lithium content, and it is frequently listed as associated with quartz, magnetite, and chlorite in fictional mineral assemblages.

Etymology and classification in worldbuilding schemes usually derive ciocrlia from the fictional Ciocral region, with the name treated as a silicate mineral species in imagined taxonomic schemes that group cobalt‑bearing silicates together for narrative purposes.

Uses and cultural significance within fiction often emphasize ciocrlia’s vivid color and durability, making it desirable for jewelry, ornamentation, and plot devices related to wealth or ritual importance. As with many invented minerals, ciocrlia serves as a plausible material in worldbuilding rather than a real-world specimen. See also: list of fictional minerals.
