jagite

Jagite is a term encountered mainly in speculative geology and science fiction to denote a hypothetical mineral or advanced material. It is not listed as a recognized mineral name in major reference databases, and there is no widely accepted chemistry or crystal structure for jagite in real-world mineralogy.

In many fictional or educational treatments, jagite is described as a dense, hard silicate or mixed-oxide with a glassy to metallic luster. The color is commonly greenish, ranging from deep emerald to blue-green, though depictions vary. Sources often emphasize jagite’s supposed durability, suggesting a strong crystal network that resists fracture and remains stable under extreme environmental conditions. Its formation is typically placed in high-pressure, high-temperature settings such as deep crustal or mantle environments, or in extraterrestrial contexts like meteorites and asteroid interiors.

Occurrences and contexts in fiction frequently link jagite to technologies requiring robust materials, such as spacecraft hulls, energy storage devices, or protective armor. In educational or world-building exercises, jagite serves as a case study for how new minerals are described, named, and rationalized within a fictional or hypothetical framework.

Etymology for jagite is not standardized, since the term is not part of formal mineral nomenclature. In fictional works, the name is usually chosen for its distinctive sound and ease of association with a durable, enigmatic material.
