Rainbow Crystals
Natural holograms sometimes appear in clear quartz crystals. These ancient “iris rainbows” are optical illusions that occur when light refracts and reflects from thin cracks in the quartz. Interference patterns create the evanescent ever-changing colors. Look for varying color schemes, depending on the thickness of the cracks- from one-thousandth of an inch to one-thousandth of a millimeter.
