This specimen features a striking fluorite crystal associated with quartz and siderite from the Yindu locality. The fluorite displays an intense red to deep amber coloration that becomes dramatically vivid when backlit, revealing strong internal translucency and rich color zoning within the crystal. The cubic fluorite is well positioned in the matrix and contrasts beautifully with the surrounding light-colored quartz crystals and earthy siderite formations, creating a visually dynamic and natural composition.
