Yes, this stone is amazing as the photos! 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. 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!
