Noel,

    Every Gilson created Synthetic Opal that I have examined has shown a
    honeycomb effect. 

    Genuine Opal never shows this effect and Imitation Opal never shows
    this effect. 

    Imitation Opal (often referred to as floating Opal ) is either a
    glass or plastic and will generally have various color foil embedded
    in it.
