Varieties, structures,formations,opalescence and play-of-color of Opals have been demonstrated in detail in this paper. The nanostructures of a common milky opal have been llustrated by the TEM experimental results.According to optical theories the opalescence effect in opal is governed by the Rayleigh scattering equation and the mechanism of play-of-color in opal is mainly due to diffractions of the visible incident light by some 1D or 2D diffraction of SiO_2 Nano-particles gratings. The ways of economic development of opals are discussed as well.
