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,
Uses and cultural role attribute significant value to kivonnakrich due to purported optical stability and chemical
Etymology and history trace the name to a constructed language in which "kivonn-" means clear and "-akrich"
