Rainbow Pyrite


A really interesting and unique specimen! A brown-gray spherical concretion (or nodule) that is broken open to reveal internal shrinkage fractures that have been lined with iridescent Pyrite microcrystals. From the outside it appears to be nothing but a mud ball, but once it is opened up, quite another story. This particular piece has an exceptionally dense coating of iridescent Pyrite making the contrast between the Pyrite and the “mud” truly impressive. Note, this is completely natural – there are zero alterations to this piece – this is exactly how it is formed. Truly amazing!
