These wonders of nature are obtained from the earth’s crust. Their chemical properties play an essential role in the effects they cause on the body. These gems are formed of minerals and atoms and are subjected to intense heat and pressure for millions of years. The interlinking of bonds that hold them together produces vibrational energy transmitted from gems to the person holding them. In astrology, it is believed that these gemstones should be in direct contact with your skin. This is because this interaction allows a continuous flow of energy.
