kelvollien

Kelvollien is a fictional mineral described in speculative geology and science fiction settings. In these works, kelvollien is a rare silicate mineral noted for its green to teal coloration, a vitreous to pearly luster, and its tendency to form well-shaped crystals in hydrothermal veins.

Physical properties commonly attributed to kelvollien include a Mohs hardness around 6 to 7, a density near 3.3 g/cm3, and a moderate refractive index. Crystals are described as prismatic, often displaying color zoning. It is said to fluoresce faintly under ultraviolet light, producing a pale yellow-green glow.

Geological occurrence and formation are portrayed with kelvollien forming in high-temperature hydrothermal environments within metamorphic belts. It is typically found in association with quartz, calcite, fluorite, and magnetite. Deposits are described as rare and small, contributing to the mineral’s desirability among collectors in the fictional world.

Etymology and history within the fiction suggest the name kel Vollien derives from a constructed lexicon intended to evoke water and stone. In various works, the mineral is attributed to discovery by fictional researchers, with dates ranging across the late 21st to early 22nd century depending on the narrative. The term is used across stories to signify a visually striking and geologically intriguing specimen.

Uses and cultural context in the imagined universe emphasize Kelvollien’s value as a collectible gemstone and as a subject of mineralogical study, rather than as an economic resource, due to its rarity and fictional properties.
