The history of gems is perhaps, as old as the history of civilization itself. From the most ancient times, human beings have been using gems both for decorative as well as for healing and other purposes. 

Gems are basically of three kinds: 

  • Water based such as pearl and coral
  • Vegetable based such as amber
  • Mineral based such as by the mixture of sand, stone and chalk. 


































Onyx (Gomedh)


Cat’s Eye

These Gems have an unlimited store of cosmic rays of certain color, through which the vibrations of the planet associated with it can be obtained and hence the traits of that planet can be further amplified or strengthened. However, it is extremely crucial to first determine, which planets are to be strengthened in a chart. The most elementary and ridiculously simplistic principle is that a planet should be generally strengthened, if it is weak in the chart. The caution to be aware of is that we should be careful in strengthening the natural malefics, even if they are weak. If the benefics are weak, it would be safe to strengthen them. It is a folly merely to go by the Sun Sign or the Moon Sign or the Sign occupied by the Lagna. The natural as well as the functional malefics/benefics should be ascertained as described in the chapter on Yoga’s. Thus, if a natural malefic, if it is also a functional benefic, can be strengthened. Similarly, the Yoga karakas can also be strengthened. Further, the lords of 1,5,9 even though not weak, may be strengthened, so as to increase their positive energy in a Horoscope.

But, if a wrong choice is made, the use of gems can be more harmful and would give extreme (and sometimes, irrelevant) adverse results, than the use of prayers. Let one thing be very clear. If a native chants mantras or recites prayers prescribed by his religion of birth, such recitation, even though not specifically called for remedial purposes, will never do any harm to the native. If the proper meaning of the prayers is brought to the mind, while reciting, the effect will be even better. But even otherwise, the mantras will never ever cause harm. On the other hand, the use of the wrong gem can have devastating and adverse effects on the native. We shall now take a cursory study of the gems.


This is a red colored gem and come in various shades of red, but the shade of a grain of pomegranate is perhaps the best.

Availability: It is found in Burma, Thailand, Sri Lanka, Russia, America and Australia and also from Mysore in India.

Pearl is a gem of the water element and is obtained from a worm by the name of Mollusk (Oyster). Out of 35,000 such worms, perhaps only 21 are useful and of these also, only hardly 3 are perfect (without any blemishes). The longevity of these creatures is 7/8 years, during which they yield pearl twice or thrice. Pearls are of white, yellow, pink, green, blue or even gray hues. Natural pearls are of course the best. But they are extremely rare and hence quite costly. Thereafter in descending order of acceptability are cultured pearls, semi-cultured pearls and then imitation pearls.

Caution: Natives who suffer from bleeding, high fever, headaches, infections, ulcers should not use Cat’s Eye. If Ketu conjoins malefics, or is placed in 6, 8 or 12 houses, the native should not use this stone.


In all cases of use of gems, it must be clearly understood that the Gem should be in continuous friction with the skin of the native at all times.

As has been stressed earlier, prayers and the use of gems are not the end of remedial measures. The opportunities are innumerable. The propitiation of Deities, Yantras, Tantra, rituals, the use of colors, herbs, yoga, hydrotherapy, etc all collectively add up to remedial measures. In the recent past, dowsing and teletherapy, kirlian photography, judicious use of clairvoyance, clairaudience, medium ship, hypnotism, astral projections, etc. have also been added in this never ending range of remedial measures.

Yet, when a native has reached at the so called “crossroad of life” and is face to face with the hard reality of facing the consequences of his own previous karma, a somewhat simplistic suggestion can be made, i.e., either face the consequences stoically and with all humility, or proceed on a long voyage (journey). The counsel for the letter has potent astrological force of reason. For when a person goes on a long journey, he changes his place of residence and hence, forcibly alters the entire complexion of his “Progressed Chart”. This could have a great bearing on his health and fortune, for better or for worse, depending upon the advice of the astrologer. Which Nation/city can most suits a native can be ascertained (though this is a rather complex matter). But there are several instances in the past, where a native has benefited as a result of such change of residence. It could work adversely also, as indeed it did in the case of the great astrologer Sephariel, when he visited Madras, where he encountered many problems.
