This is a natural crystal of clear quartz that has a deep blue-grey layer of fibrous minerals - probably riebeckite - running throughout one side: the surface on this side shows the minerals that comprise the blue/grey phantom layering very clearly. The crystal is double terminated: one end is incomplete; the other is self-healed, with one very pretty Isis face: interestingly, some call this mineral Blue Tara Quartz - Tara being an aspect of the Divine Feminine, as is Isis! This is a very nice example of its type.
