Our shastras indicate that gems affect the human body, giving either good or bad effects. Every gem has the power to absorb the radiation emitted by a particular planet. Therefore, in order to receive its benefits, the gem pertaining to the particular planet should be worn. The native should avoid the use of gems related to malefic planets in the horoscope.
