Kivonnakrich

Kivonnakrich is a fictional mineral commonly used in worldbuilding and speculative geology to illustrate mineral formation and resource use in imagined environments. It does not exist in the real world. In fictional descriptions, kivonnakrich is a silicate mineral with a green to blue color, a vitreous to resinous luster, and a transparent to translucent appearance. It is said to crystallize in the monoclinic system, with occasional tabular crystals. Reports assign it a Mohs hardness near 7 and a density around 3.2 g/cm3; refractive indices are given as n≈1.62–1.66.

Formation and occurrence in these narratives describe kivonnakrich forming in hydrothermal veins within ultramafic host rocks, crystallizing from mineral-rich fluids during late-stage alteration. Deposits are often described in faulted basins or orogenic belts, with the largest hypothetical occurrences in the Kivon Basin and adjacent regions. It is frequently described as being associated with chromite, olivine, and magnetite.

Uses and cultural role attribute significant value to kivonnakrich due to purported optical stability and chemical resilience. It is depicted as useful for precision optical components, high-end jewelry, and ceremonial artifacts. Some fictional cultures attribute protective or focusing properties to the stone, integrating it into folklore and ritual practice.

Etymology and history trace the name to a constructed language in which "kivonn-" means clear and "-akrich" denotes stone. In the narrative, the mineral was first described by the fictional geologist Dr. Lysa Mentes around 2147.
