We love stuff growing inside other stuff! And Dendritic Opal (so named for the “dendrites” clearly seen inside the crystal) has that in spades. Dendritic Opal is a useful stone for ‘metaphysical comprehension’, which means it enhances clarity in spiritual intuition; so it can be very utilitarian for Healers and those wishing to increase their Third Eye Chakra abilities. It can be used to increase psychic visions, but user beware: if you are not used to what this means, be careful what you wish for. It is also valued highly for use in past life regressions. This crystal will combine and bring even the most intense spiritual energies into the physical realm.
