This is indeed a top quality fluorite from Yindu. The crystals are sharply defined cubes, transparent to translucent, with a glassy luster that emphasizes their geometric perfection. What makes this specimen outstanding is the intense internal color zoning when backlit, the deep crimson core ignites with a radiant glow, contrasting beautifully with the cooler violet and indigo tones that frame the edges of the crystals. The interplay between these saturated magenta-red centers and the purplish halos around them creates a dramatic, almost gemstone like effect.
