moliw

Moliw is a fictional mineral that appears in speculative mineralogy and worldbuilding discussions. It is described as a rare silicate forming under high-grade metamorphic conditions in ultramafic rocks of the imagined Asteris Range. The name is said to derive from the surnames Mori and L. Wren, authors of a hypothetical description used by writers and researchers in fictional contexts.

Its properties are described as a hard mineral with a Mohs hardness estimated at 6.5 to 7, a vitreous luster, and a pale blue to teal color in reflected light. Crystals are sometimes described as elongated prisms, and the mineral is noted for weak pleochroism and a cyan fluorescence under ultraviolet light. The assumed crystal system in some sources is orthorhombic.

Moliw is said to form during ultra-high-temperature metamorphism, within metasomatized ultramafic rocks, often in association with garnet, sapphirine, and quartz. In worldbuilding materials, it may crystallize from silicate-rich melts that interact with volatile-rich fluids, contributing to its luminous properties and perceived rarity.

Potential applications in fiction include decorative gemstones, photoluminescent components, and narrative symbolism for resilience or mystery. In real science, moliw is not a recognized mineral and has no verified occurrence or physical data.
