jemantem

Jemantem is a fictional mineral that appears in science fiction and fantasy works, as well as in some tabletop role-playing games. It is not a real mineral recognized by geology.

In many depictions, jemantem is a transparent to translucent crystal that glows faintly, often ranging in color from pale blue to violet. Authors frequently describe it as having a high refractive index and a distinctive inner luminescence. The precise chemistry and crystal structure vary by setting, but it is typically portrayed as highly stable and exceptionally hard. Its fictional properties can include energy storage, superconductivity, or field manipulation.

Formation and distribution of jemantem are explained differently across works. Some stories describe it forming deep beneath planetary crusts under extreme pressures, while others attribute its origin to meteoritic or geothermal processes. It is usually portrayed as very rare, coveted, and difficult to mine, with extraction posing environmental or ethical challenges in plotlines.

Uses and cultural role often center on its value and power. Jemantem may power advanced technology, act as a catalyst for energy systems, or fuel ceremonial artifacts and psionic or magical phenomena. It can function as currency or as a political lever due to its scarcity and perceived worth. In narratives, control over jemantem frequently drives conflicts between factions, civilizations, or individuals.

Notes on fictional status: Because jemantem exists only in fiction, its attributes differ across works. For canonical details, readers should consult the specific source material. See also: gemstone, fictional minerals, energy crystal.
