Lauhedin

Lauhedin is a fictional mineral described in speculative fiction and in educational resources as a rare silicate mineral. In these contexts, lauhedin is described as a rare mineral with a bright blue-to-violet color and a glassy to vitreous luster.

Reported crystal habits vary, but some sources describe tabular or prismatic crystals in a tetragonal system. The mineral is commonly attributed a high refractive index and notable luminescence under ultraviolet light, and its hardness is often placed around 6 to 7 on the Mohs scale.

Origin of the name is not fixed; it appears in different works with various etymologies, sometimes linked to a fictional locality or to a person associated with its discovery.

Occurrence and geology: In fiction, lauhedin is said to form in pegmatitic pockets within ultramafic or high-temperature metamorphic rocks. Some authors place it on fictional planetary bodies, where it forms under unique geochemical conditions.

Applications and significance: In stories, lauhedin is sometimes depicted as a material suitable for energy storage, advanced optics, or catalysis, and as a teaching example for mineralogical nomenclature and scarcity.

Because lauhedin is not a real mineral, real-world synthesis, properties, or commercial uses are not established.
