These are crystals that are blue in colour and are often associated with the throat chakra or third eye chakra. Those interested in metaphysics will often work with these energetically a blue healing ray of light, which can be associated with many energies of the spiritual world including archangel Michael, the Christ consciousness and Mermaid frequencies.
Dolphin energies and the christ consciousness are often experienced as a blue ray of light. The blue ray can represent wisdom of all kinds, it can also invoke calm and deep states of bliss.
Of course, crystals of the Blue Ray have many other properties well above and beyond what we are describing here.
