kumerust

Kumerust is a fictional mineral introduced in speculative geology and science-fiction literature. It is described as a dense, metallic material with unusual magnetic and conductive properties that set it apart from ordinary iron-nickel alloys.

In common fictional renderings, kumerust has a Mohs hardness around 6 to 7, a high density, and strong magnetic susceptibility. Descriptions often mention a metallic luster with a slate-gray to blue-black color and a crystalline or layered structure.

In these narratives it is said to form in deep, high-pressure crustal pockets or within carbonaceous meteorites, occasionally associated with tectonic or planetary processes. The precise chemistry is variable, with suggested compositions including iron-group elements and trace alloying metals.

The name is used in various works and fan encyclopedias, sometimes tracing to a fictional researcher or to linguistic roots within the imagined world. It is not recognized by real-world mineral databases and has no verified specimen.

In fiction, kumerust is sometimes proposed as a material for advanced technologies, including durable structural components or energy-related applications, although those properties are speculative and depictions are not grounded in real science.
