Iron oxides give the reds, oranges and yellows found across the majority of banded agate. Blue and grey in chalcedony usually work differently: there is often nothing blue in there at all. The colour is produced by light scattering off structures far too small to see, the same physics that makes the sky blue rather than transparent.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eWhich is why this piece will not look the same in two places.
