Fluorite - Khối bát diện Fluorite tự nhiên "Phát quang" (Trung Quốc)

I was surprised by how well these crystals catch light given their raw finish—the natural octahedron faces have a subtle gradient that shifts from pale green to violet. It’s a solid specimen for any collection, though the fluorescent effect is very faint unless you hold it under a UV source.

The octahedron faces are so cleanly defined that it looks almost machined, though it's clearly natural. Under direct light, there's a subtle glow that makes the whole piece feel alive on my shelf.

The crystals have surprisingly sharp, clean edges for natural specimens, and the octahedron shape is perfectly defined. Under a blacklight, it glows a soft, ethereal blue that lasts a few seconds after the light goes off. Really happy with this piece.
