Blue Fluorite Crystal – UV Reactive – Yaogangxian Mine, Hunan

This Fluorite crystal specimen originates from the renowned Yaogangxian Mine in Hunan Province, China, a locality celebrated for producing well-formed and aesthetically striking fluorite crystals. The specimen features a deep blue coloration, characteristic of fluorite’s diverse palette, and exhibits a cubic crystal system with distinct step-like growth patterns that enhance its geometric appeal. Embedded within the crystal are subtle calcite inclusions, adding textural contrast and complexity to the overall appearance.

Fluorite (CaF₂) is known for its vitreous luster and relatively moderate hardness of 4 on the Mohs scale, which requires careful handling to avoid scratches or damage. This particular specimen also displays UV fluorescence, a sought-after property among collectors, making it a unique addition to any mineral collection or display.

The combination of its origin, crystal form, and calcite inclusions contributes to the specimen’s collector value, as Yaogangxian fluorites are prized for their clarity and vibrant colors. To preserve its condition, it is advisable to avoid prolonged exposure to direct sunlight and to handle the crystal with care, ideally placing it on a stable surface away from potential impacts.
