A very interesting and unusual specimen in which individual free floating cubes of skutterudite? have been almost totally replaced by pale pink erythrite microcrystals.   Many of the cubes represent epimorphs, others pseudomorphs and these frequently show the existence of chemical zoning within the cubes.   These pseudomorphs range in size from 1 to 2mm and are within a dense mixed sulphide matrix with interstitial quartz.
