Opal is one gemstone which is very much different in the crystalline structure and hence the name mineraloid was termed right for describing an opal. The ardent color play is due to the presence of tiny silicon sphere like patterns. This refracts the light on each sphere to throw a range of colors, which is called as sheen or scintillation. The color play is based on the intensity of the silica spheres. Most opals are cabochoned to maintain the color play and also in different shapes that maintain and enhance the play of colors. Fire opals are faceted at times, but all this is entirely based on the refractive nature of the densely populated spheres.
