Iris Agate is a banded agate where you can view a beautiful display of colors when light is passed across it. It is a normal stone when you see it without light falling on it. The term “iris” in iris agate depicts the display of rainbow-like colors. This is the reason some people call it “Rainbow Agate”. The iris effect on this agate is due to the translucent or transparent parts on the stone which have fine bands in them. The first specimens of this agate stone were found in 1933 by Fred S. Young, who was then the publisher of the Oregon Mineralogist. Since then various expeditions were undertaken to discover more of these stones. When light falls on the agate, it meets the corners of the small bands. These bands interrupt the flow of light and force it to take different paths through the thin bands of the agate. Thus, the bands work as a natural diffraction grating that diffracts the light and presents a display of spectral colors.
