Carlhintzeite is a rare, stable alumino-fluoride mineral with the formula Ca2AlF7·H2O. It typically forms transparent to translucent crystals that are colorless or white, displaying a vitreous luster and a triclinic crystal system. The habit is commonly radiating or bladed, and specimens are often prepared as micro-mounts to accommodate their small size.

About Carlhintzeite
Notable occurrences are reported from China, where high-quality micro-mount material has been collected. Collectors appreciate Carlhintzeite for its rarity and its delicate, needle-like or blade-like aggregates that emerge from coatings or cavities in host minerals. Its simple, pale appearance contrasts with the complexity of its chemical composition, making it a compelling addition to a focused collection of halide complexes and alumino-fluorides. While its physical properties are modest, the mineral’s accessibility primarily as micro-mounts appeals to specialists seeking niche specimens that illustrate the diversity of fluoride chemistry in minerals.
