[QUOTE="Hawkear, post: 661156, member: 4728"] Nothing is certain from remote images. Just picking up on clues. Another one maybe the area of refraction (rainbow colours). A prismatic thickness of glass can do that. There appears to be an white opaque area (crack or inclusion) where that prismatic light separation is projected and can be seen in a single view In the photograph. Correct me if I am wrong but I understand that natural silicates like opal will also display a range of colours, but I believe they will flash with one colour at a time rather than in a continuous spectrum that can be photographed from one viewpoint at any one time. Maybe our opalites could comment on my presumption there. [/QUOTE]
