Opal is unique in its color and luster. Its rainbow-like brilliance is colorful and mosaic-like, full of mystery, and is unmatched by other gems. Although it is called opal, it is not a single color. If it is only white, it has no value. Transparent, red, yellow color, mostly white and blue in Australia, one of which is dark like peacock feathers, called black opal, very beautiful, so the price is particularly high. The opal is a gemstone containing a silicic acid component, which blooms like a rainbow and has a high price. As a result of electron microscopic observation of the opal, it can be found that the particles containing carbon dioxide inside are arranged neatly and densely, and the voids of the particles contain water. When the light is incident, it is decomposed into seven colors. The rainbow is beautiful and shining.
