tratiach
Tratiach is a fictional mineral described in speculative geology and science fiction as an extremely rare silicate with exceptional strength and unusual optical properties. The name is used across different works, and there is no single canonical definition. In most depictions, tratiach is a dense, hard mineral with a Mohs hardness near 9, a refractive index that yields a vivid blue-green to violet color, and a bright, ultraviolet luminescence. It is often described as exhibiting anisotropic crystal growth, forming prismatic or tabular crystals in faulted veins.
Geology and formation: In fictional accounts, tratiach forms only under highly specific conditions in subduction-zone metamorphic
Distribution and availability: Tratiach is portrayed as extremely rare, with only a handful of specimens known
Uses and significance: Within narratives, its extraordinary hardness and potential energy storage or superconducting properties make
