Precious opal - the rarest, most sought after and also the most valuable. These are natural opals that were formed either by the weathering process (Australia) or by volcanic activity (eg Slovakia, Ethiopia) and have the ability to opalescent. Ie. that the incident light radiation decomposes in the spectrum of monochromatic light radiation, which the human eye perceives as spectral colors (red, orange, yellow, blue and purple). This "play of colors" or color change, as it is also popularly called opalescence, then creates an incredible kaleidoscope of color patterns and changes. For this property, natural expensive opals are sought after especially in jewelry stores for jewelry purposes.
