We have so far clarified that every gemstone has some kind of miraculous powers which is often referred to as divine powers. According to its color, every gem represents a planet of the matching color. As for example, Venus has white color so it is represented by diamond. Red or pink ruby similarly represents the sun and yellow sapphire represents Jupiter. 

 

Every gemstone has the power to draw energy or beams from its respective planet and channelize it into the wearer's body. This property of a gemstone is helpful in exerting its influence in miraculous ways.

Each gem of the Navratna category represents a planet of the solar system. When we wish to enjoy the favorable effects of a particular planet, we wear the stone representing that planet on our fingers, neck or arm. It is also important here to know that stone of a particular planet must be worn on the finger that represents it. In astrology, every finger is believed to represent a particular planet viz. Thumb represents Venus, index finger represents Jupiter, middle finger represents Saturn, ring finger represents the sun and little finger represents Mercury. 

 

Suppose a particular planet is not strong enough in the horoscope of a person and a person was hence suggested to wear the stone that represents that planet. The stone draws positive energy from the planet and channelizes it into the body of the wearer. The planet, since then, begins to bestow its good effect on the person who then climbs the ladder of success quickly, reaps great benefits and enjoys good food. Now even if the person doesn't make fervent efforts, the luck still gives him strong support. 

 

Effects of the stones can be compared with the way modern medicine employs to remove the deficiency of vitamins in body. As for example green vegetables are prescribed to remove the deficiency of vitamin A and iron and basking is suggested to correct the disturbances in the level of vitamin D. Similarly stones are suggested to remove the deficiencies in the influence of particular planet.

 

People blinded by the dazzles of modernity do not reject the prescription of modern medicine. In fact they cannot do so. Thus, they have no moral right to reject the science that had helped since millennial, millions of people to live a healthy life and reap good fortune especially when they have not tested the validity of it themselves. It is possible that such people or their relatives might have worn some stone and did not receive expected results. Such cases are exceptional but not truth entirely. If you have worn a wrong stone at a wrong time for a wrong planet and could not get expected results or suffered adversely, you are prone to reject whole science of gemology as mere superstition. But such petty instances are not enough to prove the whole science of gemology wrong. Often people fail to get real gemstones or they get underweight gemstones which do not exert full influence. Such cases also cause suspicion to arise in people's mind. 

 

There are many more reasons behind the gemstones being effective to channelize the influence of a particular planet. Each of the nine planets represents many fields of activity, things and human conditions as well as diseases. Suppose a person is suffering from a disease which is proving incurable even to the best of the treatments. The person ultimately consults his astrologer. The astrologer studies the horoscope of the patient and finds out the planet responsible for the disease and prescribes him a particular gemstone. The patient follows the advice and wears the gemstone and his disease miraculously disappears within a few days.
