We have known about gem stones from our ancient time, they also find mention in ancient puranas as all the nine vedic astrogical gemstones have been clearly mentioned.
Precious stones (and metals) have fascinated mankind by their sheer luminosity and colour, and have served as items of adornment reinforced by a belief in their occult powers. Since Vedic times it has been an accepted belief that gems have curative and prophylactic qualities that influence man's fate. People seek guidance from wise astrologers to select a particular gemstone that will enhance their fortune and protect them from evil planetary influence.
In this feature, I shall discuss the talismanic qualities of various gemstones. While choosing one’s birthstone it is important to select it after detailed study of one’s birth-chart. One should neither select one’s birthstone according to the month in which one is born nor on the strength of one’s Zodiac sign. These are broad classification and hence may not be very effective. It is only through a proper study of the birth-chart of an individual through astrology that can reveal the best gemstone for the person.
After erecting the horoscope, the astrologer has to ascertain the strength of each planet and their effects on the individual. A planet found weak in birth-chart tends to harm and hinder the progress of a person. In such an event, astrologer advises him/her to wear the gemstone governed by this particular planet. Sometimes the astrologers advise to wear particular gemstones, whose ruler is situated very strongly, in one’s nativity. This helps to enhance the good qualities indicated by the planet to assure progress, prosperity, physical and mental well being of the person. Even the physical characteristics of an individual could give us a clue as to the person’s ruling planet. Once you have understood the ruling planet by observing the physical built, the personality, likes and dislikes, and the choice of profession, it will become easier for you to choose your lucky gemstones. In this feature on gems, I have tried to elucidate qualities of each gemstone, and also the professions ruled by different planets.
There are nine planets, nav-graha, governing nine gems, nav-ratna, traditionally accepted in Hindu astrology. These are Sun, -governing ruby, Moon - pearl, Mars – coral, Mercury – emerald, Jupiter, - Pukhraj or yellow sapphire, Venus - diamond, Saturn - Blue sapphire, Rahu, - Hessonite and Ketu – cat’s eye.
