Villiaumite specimens for sale

Villiaumite is a rarer fluoride mineral with the chemical composition NaF. It forms transparent to pale to deep crimson crystals that can be small tabular shapes or prismatic masses, often exhibiting a vitreous to resinous lustre. In some specimens, the fluorescence under short-wave ultraviolet light is notable, a feature that makes high-quality pieces particularly sought after by collectors. Notable localities include Russia and Namibia, with other important examples reported from diverse settings, reflecting its relatively restricted market occurrence. Collected samples often come from uranium- or fluorite-bearing deposits where nodular or vein-hosted pockets can yield well-formed crystals, sometimes interconnected in microcrystalline aggregates.
