This is an epigenetic inclusion of iron oxides, i.e. that it was formed inside a fracture of the quartz after it had crystallized.
When the thickness of the hematite film is of the same order of magnitude as the wavelength of light, thin-film interference is created which causes the iridescence.
As you can imagine this is an extremely rare phenomenon.
Natural colors.
Very good quality.
