Gemstone Information

  • This coloring is believed to be caused by very small Tourmaline, Rutile, or Zoisite inclusions within the Quartz.
  • Blue Quartz works mostly with the Throat and Third Eye Chakras.
  • By focusing in on the Third Eye Chakra, Blue Quartz can help one to connect to higher realms and work with ascended beings, and brings great clarity to psychic visions and enhances dream work. 
  • Blue Quartz enhances organizational abilities, self-discipline and orderliness by balancing the Throat Chakra and enhancing communication between upper and lower Chakras.
  • Physically, Blue Quartz is said to enhance the immune system and encourage proper function of the Lungs, Heart, Throat, and Eyes.

    • Her gemstone changed from a circular gem with a hexagonal facet (the same shape as Amethyst's) to a triangular, diamond-esque shaped gem (the same shape as Jasper's).
    • She gains a nameplate.
