This dazzling cluster of iridescent andradite garnets from Nara, Japan is a top-tier specimen in our collection—showcasing some of the brightest surface diffraction seen at this size. Measuring 22.75mm x 21mm x 17.65mm, the piece features a dense aggregation of sharp, well-formed crystals that shimmer with an almost mirror-like metallic luster, flashing brilliant hues of electric green and fiery orange across every angle.

The iridescence here is exceptionally intense, with lamellar diffraction patterns that ignite under even modest lighting. Each crystal is coated in a smooth, reflective sheen that enhances the vividness of the color play, making this specimen appear almost electroplated in chromatic metal. The balance of crystallization and color saturation is rare for material from this locality, where muted or textured surfaces are more common.

Known for producing some of the most coveted rainbow garnets globally, Nara’s deposits are limited and highly selective, making fine, bright pieces like this increasingly difficult to source. The geometry, condition, and sheer vibrancy of this cluster make it a gemological standout—a miniature jewel of Japanese mineralogy that embodies both structural beauty and optical fire.
