The name for the opal comes from the Sanskrit word "Upala", meaning precious stone or stone par excellence.
The Greek word "opallios" means "to see a change of colors".
The opal is an amorphous substance that belongs to the silica group. It is formed by a series of spherical microscopic structures of various sizes, which diffract light to show a beautiful play of colors.
