The law of this world is that one who takes birth is sure to die. Like a person dies after a certain age limit. Similarly, these gems also have an age limit. Which depends on the mutual holding power of their crystals and on the affective power of the planets in the solar system. However, rubies can be worn for a maximum of 4 years. It is not effective after 4 years. After this, a new ruby should be worn again to get the positive effect of the sun.
