molaarset

Molaarset is a fictional mineral described in worldbuilding literature and speculative geology. It is imagined as a rare aluminosilicate with a framework that allows substitution of various cations, yielding crystals that range in color from pale blue to deep green. The term is used in fiction and educational resources to illustrate mineral diversity and mineral formation at high pressures.

Composition and structure describe molaarset as generally a silicate with aluminum and magnesium in the framework, along with trace iron, manganese, and rare earth elements. The crystal system is often cited as monoclinic or orthorhombic, with a dense, prismatic habit. It reportedly exhibits a vitreous to subadamantine luster and a Mohs hardness of roughly 6 to 7. Under ultraviolet light, the mineral is described as luminescent, emitting a blue-green glow.

Occurrence and formation place molaarset in subduction-zone metamorphism and ultramafic igneous contexts within the fictional corpus, often found in deep crustal xenoliths. It is said to crystallize at high pressures and moderate temperatures, with formation influenced by trace element concentrations in the host rock.

Naming and usage explain that the name derives from the Molaar region in the fictional setting, with the suffix -set indicating a mineral. In worldbuilding contexts, molaarset is sometimes proposed as a gemstone for storytelling or as a benchmark material for photonic applications in speculative technology.
