Inclusions and Phantoms
Although the transparency of the phi crystals is highly valued, Dr. Marcel Vogel and his assistants found that phi crystals do not have to be completely clear to be effective. In some cases, phi crystals with some internal clouding, occlusions, etc., may be more powerful than completely clear phi crystals. Phi crystals which are not completely optically clear, should not be disregarded; they may also have very important inherent properties which developed in a completely natural way. Thus, these phi crystals with inclusions may carry energies within, for example as with Kundalini or from Thor, energies that cannot be generated by a very, very clear phi crystal. Each phi crystal is an individual being with its own inherent energy; it is uniquely beautiful, creating special phantoms and/or inclusions for miraculous energies. Therefore, inclusions and phantoms have a very deep meaning. So, when buying a phi crystal, do not only pay attention to its transparency: carefully read the description and engage with the phi crystal. Thus, a phi crystal with phantoms or inclusions could carry exactly the energy that is meant for you.
