Kristallit

Kristallit is a fictional crystalline mineral that appears in science fiction and speculative mineralogy discussions. Descriptions vary by author, but it is commonly depicted as a transparent to translucent crystal ranging from colorless to pale blue, sometimes with an iridescent edge or a faint glow under ultraviolet light.

Physical properties commonly attributed in fiction include a hardness on the order of 6–7 on the Mohs scale, a vitreous luster, and a hexagonal-prismatic crystal habit. It is often described as having a high refractive index and striking birefringence, which writers use for optical effects in devices and displays.

Occurrence and formation: In-universe geology situates kristallit in deep crustal or planetary contexts, frequently within hydrothermal veins, high-temperature metamorphic zones, or as crystallization products around conductive melts. Some accounts associate large crystals with past impact events, where rapid cooling fosters crystal growth.

Uses and cultural role: In fiction, kristallit is depicted as having energy storage or semiconducting properties, and as a luminous material for signaling, art, or data storage. Its rarity and optical qualities make it a sought-after resource in trade networks or frontier settlements in the narrative world. Because kristallit is a fictional mineral, its properties are not consistent across works.
