This specimen features an exceptional electric blue fluorite associated with quartz, siderite, and chalcopyrite from the famous Yaogangxian Mine. The fluorite crystals display sharp cubic forms with an intense blue to blue violet coloration, showing excellent transparency to translucency and a strong vitreous luster. The cubes are well distributed across a contrasting light-colored matrix, creating a highly aesthetic and balanced composition. Associations with sparkling quartz, earthy siderite, and metallic chalcopyrite add depth and mineralogical interest to the piece.
