Part 2 (synthetic diamond jewelry)
Also, under close inspection with a loupe, the facet shapes of some CZs appear different from diamonds. Both gems disperse light a little differently. (synthetic diamond jewelry) Dispersion is just a scientific term for the breaking up of light into its spectral colors. With a dispersive power greater than diamond (0.060 vs. 0.044), the more prismatic fire of CZ can be seen by even an untrained eye. (synthetic diamond jewelry)
(synthetic diamond jewelry) Dispersion occurs based on the gem’s refractive index. In this case, refractive index simply indicates how much a beam of light will bend, based on the direction in which it is traveling when it passes between two materials of different optical densities (such as between diamond and air; or between CZ and air). (synthetic diamond jewelry) Being that CZ has a refractive index of 2.176, compared to a diamond's 2.417, diamonds are therefore said to be brighter than CZ.
