Fluorite - China

This stunning fluorite specimen from China presents a captivating cluster of cubic cleavage faces displaying a dramatic zoned coloration — rich deep purple at the tops of the crystals transitioning into smoky charcoal gray and near-colorless translucent zones toward the base. The natural cleavage planes are beautifully defined, giving each face a glassy, mirror-like quality that catches light with remarkable depth. Bright orange-brown matrix material clings to the base, providing a warm earthy contrast to the cool purple and gray tones. Small accessory mineral inclusions and surface deposits add character and authenticity to this natural, unpolished gem cluster. Fluorite (calcium fluoride, CaF₂) forms in hydrothermal veins and is prized among collectors for its extraordinary range of colors, which are caused by trace impurities and radiation exposure during crystal growth. China is one of the world's premier sources for fluorite specimens, producing some of the most visually striking examples with sharp cubic form and vivid color zoning. The deep purple coloration seen here is among the most sought-after varieties, caused by color centers created by natural irradiation within the crystal lattice. This specimen came labeled and curated by C.W.B. Minerals, indicating it is part of a traded or acquired collection rather than a local find. This piece is part of Brian's curated traded collection at Iron Mountain Ranch in the Tunk Valley — a testament to his wide-ranging passion for minerals that extends well beyond the remarkable geology of his own homestead. It makes a striking display specimen that will captivate anyone drawn to the deep, mysterious beauty of natural fluorite.
