This fluorite from Yindu is especially striking when backlit, as the internal color zoning becomes vivid and dramatic. The crystals are predominantly cubic, with sharp, well-defined edges, and they show a palette ranging from deep violet and indigo at the outer edges to warm golden-orange tones glowing from the core. The translucency of the fluorite allows the light to penetrate and reveal a fiery depth, almost as if the specimen were lit from within. The transition between purple and amber hues is gradual in some areas and sharply contrasted in others, producing a dynamic interplay of colors that is characteristic of fluorite from this locality. The surrounding matrix is pale and granular, framing the crystals and enhancing the luminous effect. Overall, the piece captures the duality of geometric precision in the crystal forms with the almost molten, glowing appearance revealed by transmitted light, making it a highly aesthetic and collectible example of Yindu fluorite.
