irodaméret

Irodaméret is a fictional mineral described in speculative fiction and tabletop role-playing game sources. It is characterized as a silicate mineral with an iridescent color range and faint luminescence. In in-universe geology, irodaméret forms in hydrothermal veins within metamorphic rocks and is typically found alongside minerals such as zircon and tourmaline. Crystals are described as hexagonal prismatic, though reporting varies by source. The material commonly appears in shades of pale blue to violet, with a glassy to pearly luster. Reported Mohs hardness values range from 6.5 to 7, and some descriptions note weak birefringence under polarized light and subtle pleochroism.

Etymology and history: The name appears to derive from elements of a constructed language used in the fictional setting, with roots interpreted as "mirror" and "stone." The mineral is said to have been first documented by in-world scholars in medieval-like compendia, later appearing in gem catalogs and adventure modules. In many sources, a nominal discoverer is credited as the cartographer-mineralogist Lira Valon, though details vary between works.

Uses and cultural context: Irodaméret is primarily valued as an ornamental gemstone because of its color, clarity, and luster. In some narratives, its crystalline lattice is imagined to possess semi-conductive properties or to serve as a component in energy cores or rune devices. Culturally, it is associated with themes of reflection, insight, and resilience, and it features in fictional trade networks and treasure lore.
