Siberian Blue Quartz is a laboratory-grown crystal, which is made in Russia. It is created by a process in which natural quartz is broken down and re-grown with cobalt which is the source of the new deep blue color. Its hardness is about 6.5 to 7.  Mystic Lore: Intuitive sources say that Siberian Blue Quartz can help to activate the 5th & 6th chakras, the energy centers of communication and inner vision. It is said to enhance one's psychic abilities, such as clairvoyance & telepathy, and to increase visionary experience.
