- The Opal's beautiful colour play was an impossible phenomenon until the 1960ís when a team of Australian scientists discovered, with the aid of an electron microscope that small spheres from silica gel caused interference and refraction manifestations (Gem by Gem). The spheres, arranged in a more or less compact structure, diffracted the light entering the stone into the spectral colours (Hershel, 2005). In Common Opals the spheres are disordered or too compact to permit any light from refracting (Hershel, 2005).
