If you haven't had the pleasure of seeing a true Rainbow Calcite in person, then prepare to be amazed.  There is not really any other natural gem material that compares.  Needless to say, this does not translate particularly well to a still photograph, however, the display of colors is nothing short of astonishing; if you can see the rainbow flashes in the photos, then simply intensify this by a magnitude of 10 and you will be getting close.  Set against a completely colorless background these are magnificent - a full spectrum constantly emitting from the stone.  This is a lovely example - a manageable size and with a perfect, precision cut.  The key to these is that the Calcite must be cut from a twinned crystal - and, as is often the case, you can actually see the twinning plane running through the stone - it is not an inclusion at all, it is simply seen because the angle of the dispersion changes.  Very impressive!
