Zodiac stones have been used from times immemorial for luck and as good omens. Some astrologers also prescribe wearing of appropriate zodiac stones, gemstones, or birthstones for mitigating the malefic effects of some planets. The astrologer examines the horoscope and determines which planet (or planets) is antagonistic to the native and prescribes the zodiac stone or birthstone to be worn with details of what to wear, when to wear and how to wear.

Ruby, Pearl, Coral, Emerald, Topaz, Sapphire, Diamond, Agate, and Cat’s eye respectively refer to Sun,Moon,Mars,Mercury, Jupiter,Saturn,Venus,Caput and Cauda. At times, people do not know their time of birth, they know only the date of birth and the preparation of an accurate horoscope becomes difficult, if not impossible. Such people can be told to wear the birthstone pertinent to the date of birth. Thus, those born on the 1st, 10th ,19th or the 28th of any month can wear ruby or red coral to begin with. Then, by trial and error and after consultations the correct zodiac stone or gemstone can be worn
