The list of healing and metaphysical properties provided below is the result of my own work with crystals:
Clear quartz has a high vibration and can amplify negative energy as easily as positive energy, so be careful. It is a wonderful crystal to use for the crown chakra as it brings in the clearest information.
Quartz can be used on all chakras as the white light within quartz contains all colors. I like using quartz druze and clusters to cleanse my crystals. I have some in my healing room and in my bedroom.
Amethyst is the spiritual smelling salt of the crystal kingdom. This crystal awakens one to their own inner wisdom. The stone is typically used in working with the third eye chakra, but I use it with my crown chakra too. Amethyst was used in ancient Greece for sobriety. Amethyst is a good ally for protection during your dreamtime or during times of grief.
Lapis Lazuli is helpful in assisting one to speak their truth. First it seems to open me up to feeling the truth, so then it can be spoken. A stone of strength and support it is also calming. I use this crystal with my throat and crown chakras as it also opens the third eye. According to John Van Auken, a Director at the Edgar Cayce organization, the Association for Research and Enlightenment (A.R.E.)., Edgar Cayce recommended Lapis Lazuli, “More than any other stone!” There must be something to it right? Try this stone on your third-eye for yourself.
Malachite assists one in going deep into their core. The stone supports deep healing ultimately leading to positive growth. Be prepared to face your issues when using this stone. I like to wear malachite close to my heart. Looking at the images alone at this point gets the energy in my heart chakra moving. The energy of this stone is magnetized, so be ready for interesting energetic sensations.
Citrine is a crystal of vitality, exuberance, and happiness. Citrine has a unique ability to uplift and easily dissipates negativity and lethargy with its effervescence. I like to carry one in my car for protection and to increase prosperity by placing it with my change. Meditating with a citrine crystal at your solar plexus chakra is revitalizing. Focusing on the solar plexus chakra brings courage and confidence.
Carnelian is a beautiful deep orange to red agate. Many times you can see beautiful white layers between the orange strata. Carnelian is a crystal that is supportive of the sacral chakra. It assists one with issues related to sexuality and reproductive health. Awakens sexual desire in those lacking.
Red Jasper is a dark orange to red stone. It is vibrant! And yet gentle and soothing. Red Jasper can be used with the sacral or root chakras. The stone is supportive, protective, and down to Earth helping you stay grounded.
