Aesthetic specimen of blue fluorite with quartz and siderite, originating from Yindu, Inner Mongolia, China. The fluorite crystals display a vibrant blue coloration with subtle purple zoning, typical of this famous locality. They are sharp, transparent, and exhibit well-defined cubic forms with a gentle glassy luster. Delicate quartz crystals are scattered across the matrix, adding sparkle and textural contrast, while clusters and coatings of warm beige to honey-colored siderite provide a striking complementary tone to the cooler fluorite hues. The combination of these three minerals forms a balanced and elegant composition that is both visually appealing and mineralogically significant.
