Geene

Geene is a fictional mineral described in speculative fiction as a rare, luminescent silicate with exceptional energy-storage and optical properties. The term is used in several narratives to denote a crystal capable of storing electrical energy and emitting light when stimulated. Geene crystals are depicted as colorless to pale blue, with a glassy to translucent appearance, Mohs hardness around 4–5, and a high dielectric constant.

In the stories, geene forms in high-temperature hydrothermal environments and is often found with quartz and fluorite. The supply is limited, leading to regulated mining and ethical debates within the worldbuilding. Synthetically produced geene is described as possible through advanced high-pressure synthesis, enabling controlled luminescence and enhanced conduction. Proposed applications include compact energy storage devices, optical processors, and sensors. Cultural depictions vary from practical resource to symbol of untapped potential. Real-world researchers sometimes use geene imagery as a placeholder for discussing energy materials, mineral deposition, and scarcity.
