ABOUT GEMS:- The Gems are classified as precious and semi-precious stones based on their cost. Gemstones are minerals with definite crystalline structures and chemical compositions. They are composed of atoms of energy. Each & every gem has its own chemical configuration, refractive index and physical properties. It is like a filter prism. It filters a specific ray according to its chemical and physical property. The specific wavelength absorbed by the gem stimulates our body cells. The right gem helps to ward off the evil effects and acts as a protective talisman. Gems are classified into two categories, cold and hot. Pearl, blue sapphire and topaz are referred to as cold gems, while ruby, diamond, cat's eye and red coral are known as hot gems. How Gemology works: - Gems generate constructive vibrations in the body. This helps counter the negative malefic powers released by the planets. When a specific gem is worn, it emits positive energy and provides a protective aura for the wearer. Duration: - Every gem has a specific life span. After this period, one should change the gem as it loses its impact for that particular individual. Nevertheless, the same gem will be effective for another person. Wearing of gems: -Gems should be worn after a proper selection. One should wear gems based on the planetary positions in the individual's horoscope. A trial period should be incorporated before any gem is worn. The proper purification and activation of a gemstone makes it effective. Gems should be worn after a pooja is performed in order to ward off negative planetary influences. It takes several months before the positive vibrations are activated, but the moment it is removed, the beneficial effect is instantly lost.
