Opal is the most vibrant gemstone of all. It shows an iridescent play of the dazzling colors varying from the point of seeing. This eye capturing phenomenon is often known as the opalescence. The derivation of its name is credited to the three sources, ‘Upala’ (precious stone) from Sanskrit, ‘Opalus’ form Latin and Opallious (change of color) from Greek.
