This 25.55 carat crystal from near Tenkawa Village, Nara Prefecture, is a rare and visually striking example of iridescent andradite, sourced from one of the most iconic localities on Earth for this optical phenomenon. Measuring 16 x 11 x 8 mm, it carries a distinctive aesthetic—its surfaces are nearly fully covered in colorful contact zones, creating a textural mosaic of spectral shimmer.

Rather than showcasing singular crystal faces, this piece offers a more organic and chaotic beauty, where light dances across fragmented planes and layered edges. It’s a different—but deeply compelling—expression of the Tenkawa aesthetic, embodying the locality’s unique lamellar interference and diffraction structures in an almost painterly arrangement.

A rare specimen for both collectors and optical mineral enthusiasts—a geological artifact of color, resonance, and crystalline complexity.
