lagaramma

Lagaramma is a fictional mineral used in worldbuilding and speculative fiction. In most depictions it is a rare silicate crystal notable for its blue-green iridescence and remarkable resilience. The mineral is described as forming in deep hydrothermal vents and volcanic arcs within a fictional archipelago, where chemical gradients foster slow crystal growth.

It is said to have been first documented by exploratory expeditions in the late 22nd century. Extraction is described as difficult due to extreme depths, high pressure, and toxic plumes; mining is predominantly conducted with autonomous underwater vehicles under strict regulatory frameworks in the story’s setting.

Physical properties attributed to lagaramma include a Mohs hardness near 9.5, high thermal stability, and luminescence that intensifies under ultraviolet light. Its purported electrical conductivity and photonic responses have made it a candidate for speculative energy storage devices and advanced optical components in some narratives.

Culturally, lagaramma serves as a symbol of technological prowess and resource control. In several works, it is the subject of trade routes, diplomatic skirmishes, and ceremonial artifacts. Real-world in-universe regulations resemble speculative commodity markets, with licensed mining, export restrictions, and environmental safeguards.

Name and etymology are described within the fiction as originating from the Lagaran language, where laga means light and ramma denotes stone. The term thus conveys the idea of light-bearing stone, a fitting metaphor for its described luminescence.
