Source/Origin: Yaogangxian Mine, Hunan Province, China
Key Features: Distinct phantom inclusions, vibrant blue cubic fluorite, UV-reactive fluorescence, quartz matrix for contrast
Introduction:
This exceptional Blue Phantom Fluorite on Quartz originates from the Yaogangxian Mine, one of the most famous mineral localities in the world. This specimen features sharp, cubic blue fluorite crystals exhibiting distinct phantom zoning, a highly sought-after feature that captures the mineral's natural growth history. The translucent, jelly-like fluorite cubes rest atop a sparkling quartz matrix, adding both contrast and aesthetic appeal.
Under UV light, this fluorite displays a vivid blue-purple fluorescence, further enhancing its desirability among collectors. With its well-balanced crystal structure and striking clarity, this piece is an outstanding addition to any high-end mineral collection.
Geological Details:
Fluorite is a calcium fluoride mineral (CaF₂) belonging to the halide mineral class and crystallizing in the isometric (cubic) crystal system. The Yaogangxian Mine is well-known for producing world-class fluorite specimens with exceptional clarity and color zoning.
The phantom inclusions visible in this specimen are a result of intermittent mineral deposition, where variations in environmental conditions cause layers of fluorite to grow at different rates. This effect creates the striking ghost-like internal structures seen within the crystals. The presence of a quartz matrix suggests that this fluorite formed in hydrothermal veins, where silica-rich fluids provided a foundation for its cubic growth.
Rarity & Collector’s Value:
Fluorite specimens from Yaogangxian Mine are highly prized due to their vibrant colors, zoning patterns, and well-formed cubic structures. The phantom effect in this specimen adds to its uniqueness, as only a small percentage of Yaogangxian fluorites develop such distinct internal growth patterns.
Additionally, this piece exhibits UV fluorescence, glowing with a strong blue-purple hue under UV light, a characteristic that enhances its visual and scientific appeal. The combination of phantom zoning, UV reactivity, and an undamaged cubic crystal formation makes this specimen a premium collector’s piece.
Display & Care Recommendations:
This fluorite is best displayed under controlled lighting to highlight its internal phantoms and cubic structure. A UV light source can further enhance its fluorescence, making it an excellent feature for any high-end mineral showcase. Due to fluorite’s moderate hardness (Mohs 4), it should be handled with care and kept away from prolonged exposure to moisture or direct sunlight to preserve its clarity.
