This 19.25 ct Japanese rainbow andradite garnet is one of the most unique and visually complex specimens we’ve encountered from this coveted locality near Tenkawa Village, Nara Prefecture, Japan. Measuring 17mm x 14mm x 14mm, the crystal exhibits a remarkable natural cross-section along one side, revealing an intense layering of multi-colored diffraction planes.

The lamellar iridescence bursts through with stacked bands of electric color—vivid greens, magentas, blues, and golds—tracing the internal architecture of the crystal’s growth in fine detail. This rare view into the garnet’s structure offers an extraordinary look at how the optical phenomenon develops through sequential mineral layering.

The main termination faces glow with warm bronze and pinkish iridescence, while side facets shimmer with subtle interference effects, giving this piece both surface beauty and interior complexity. A true collector’s crystal, blending science, geometry, and visual magic in one perfectly preserved garnet.
