 The amazing optical effect on this jewelry is created by using the principle of “diffraction”. Thousands of microscopically small groves are etched into patterns with the incredible accuracy of a Laser.  These grooves form a “Diffraction Grating”.  When light is reflected from the surface of the jewelry it breaks into the component colors of the spectrum.
