Certain crystals such as smoky quartz and black tourmaline are believed to have the ability to absorb negativity and electromagnetic “smog;” and to put out pure, clean energy.
Wearing a black tourmaline around your neck protects you from electromagnetic emanations, including cell phones and computers, and turns back “psychic attack.”
Amber and jet jewelry will also protect your energy.
A large smoky quartz cluster or shaped point can look stunning as a decorative object as well as serve a practical cleansing purpose. Place one between you and a source of electromagnetic smog or geopathic stress or position it on your desk.
An amethyst geode has the same effect as smoky quartz.
If you find that computers have a debilitating effect on you, place a fluorite cluster or a piece of lustrous lepidolite beside it, and you will be amazed at the difference in how you feel.
A large citrine geode is decorative and will also help you to attract and keep wealth. Place it in the wealth corner of your home (the farthest left rear corner from the front door.)
