These are one of the most distinctive of all Garnets.  From a well known (and now completely off-limits) Japanese locality,  the iridescence is caused by the twinning of the garnet crystal and is close to the surface only - too deep a polish will remove it entirely.  Anything symmetrical from this locale is scarce - these are often left as freeforms to lessen the likelihood of polishing away the iridescence.  A beautiful example with a fine degree of color and superior luster; remarkably, there is even some translucency to the garnet's bodycolor.  One of the few examples of stones from this find that could easily be incorporated into jewelry.
