Csíped

Csíped is a fictional mineral term used in worldbuilding, speculative geology, and related fields. It denotes a rare metallic silicate crystal noted in several online guides for having a distinctive plate-like habit and a sharp conchoidal fracture. In most accounts, csíped forms in high-temperature hydrothermal veins adjacent to igneous intrusions and is found in small, high-purity crystals. It is not recognized by real-world mineralogy.

Physical properties commonly attributed to csíped in fiction include a hardness around 6–7 on the Mohs scale, a density near 7.5 g/cm3, and a metallic to sub-metallic luster. Coloration ranges from dark steel-gray to bluish-black, occasionally with faint iridescence under certain lighting. The crystals are usually described as brittle with conspicuous cleavage, and the imagined taxonomy places them in simple crystal systems for narrative convenience.

Industrial and cultural use in fictional contexts centers on edge retention and sharpness, making csíped desirable for precision cutting tools and decorative jewelry within the imagined world. It also functions as a storytelling device to signal rarity and value. Because csíped is fictional, real-world mineral data cannot be applied to it, though it can serve as a pedagogical example for discussing mineral properties in speculative settings.
