Splendoris

Splendoris is a fictional mineral name used in speculative geology and worldbuilding. The term derives from splendor, reflecting the mineral’s reputed luminous appearance. In its standard worldbuilding description, splendoris forms in hydrothermal veins within ultramafic rocks and yields a distinctive iridescent or pearlescent luster. It is described as transparent to translucent with a vitreous to pearly surface, a hardness around 6 to 7 on the Mohs scale, and a high refractive index that produces bright colors when viewed from different angles. The mineral is said to crystallize in a trigonal or hexagonal system, often forming prismatic or tabular crystals, and it commonly occurs alongside quartz, magnetite, and chromite. Chemically, splendoris is depicted as a silicate- or borosilicate-rich phase with trace rare earth elements that influence its iridescence. In lore and decorative arts, splendoris is valued for its strong color play and brightness, making it a popular material for simulations of gems in games and stories. No natural occurrence or samples exist outside of fictional contexts, and the term does not correspond to a verified mineral in real-world geology.
