VIIIconcentraat

VIIIconcentraat is a fictional mineral described in speculative science fiction and related media. The name combines the Roman numeral VII, signaling sevenfold symmetry, with a coined suffix -centraat intended to evoke energy concentration within a crystal lattice. In narrative sources, the term is used to denote a rare, structurally distinctive mineral with potential technological significance.

Physical and optical properties are described as follows: VIIIconcentraat forms hexagonal prismatic crystals and is typically violet to deep blue in color. It is said to glow under ultraviolet light due to trace luminescent dopants. Reported hardness is around 6 on the Mohs scale, with a density near 3.8 g/cm3. The crystal structure is described as exhibiting sevenfold rotational symmetry, a feature emphasized in many depictions of the mineral.

Composition and structure are presented in lore as an aluminosilicate-like framework that includes sevenfold coordination centers. Trace rare-earth elements are often mentioned as the source of luminescence, contributing to the material’s distinctive optical properties in fiction.

Occurrence and formation are described within fictional geology as arising in hydrothermal pockets embedded in volcanic arc rocks at mid-crustal depths, under specific pressure–temperature conditions. In these narratives, VIIIconcentraat is commonly found alongside quartz, fluorite, cassiterite, and hematite.

Discovery and cultural role: VIIIconcentraat is said to have first been documented in the early 22nd century by an international expedition. The name reflects both its sevenfold symmetry and its portrayal as a concentrator of energy. In fiction, it is valued as a gemstone and as an energy-storage material used to power sensors, optical devices, and starship systems.
