It was only in the last centuries that a few theories appeared suggesting possible effects a pyramidal shape can have on humans and even objects.
It is said that the pyramids may represent a unique source of life force, capable in certain conditions to recharge the human body with positive energy.
Nowadays you may encounter a variety of pyramids made of Rock Crystal, Amethyst, Fluorite, Nephrite, Carnelian, Rhodonite, Cacholong, Malchite and Lapis Lazuli.
These are usually quite small, so that they can be easily hidden in your palm.
It is also believed that talismans shaped as pyramids are reliable protectors against harmful and unwanted radiation, emanating either from earth or industrial sources. They may have beneficial effects on cardiovascular, sexual and motor systems as well as the brain function.
Some believe pyramidal talismans affect positively the chakras.
The usual advice is to keep such pyramids both at home and at workplace.
Different minerals in the pyramid may produce different effects. Rock Crystal or Amethyst may help to achieve peace of mind, shake off depression; Pink Quartz and Rhodonite would stabilize cardiovascular activity. Carnelian piramid, which is associated with the influence of the Sun is believed to boost one’s life forces.
