Caledonite ranges in color from dark blue to blue green. It forms in masses and small prisms, as well as coatings for other minerals. Caledornite stimulates the navel, throat, and third- eye chakras. It can help activate intuition and psychic ability, and assists in learning to utilize them once they’ve been triggered. Astral projection also benefits from the use of caledonite. The stone also helps those engaged in public speaking to keep calm under pressure.
