Unfortunately, gemstones are somewhat rashly and hastily prescribed based on 'picks' (lagna, moon, malefic, benefic). Gemstones need a careful consideration of the entire and specific charts and also after determining if that is the best suitable modality for the individual.
Not only is the quality of the gemstone of paramount importance but also the procedure around its selection, preparation of the ornament (ring etc) and when it is worn, with the mantras etc to activate what otherwise is a crystalline metal salt with a hefty price tag, if you know what I mean!
Without rehashing the entire nine yards again, I would request your attention to a URL for reading what I have written in details on this subject matter with examples at:

[quote="danrembrandt"]I WANTED TO WEAR GEMS TO IMPROVE MY LIFE.I HAD MANY TRADITIONAL READINGS AND EVERYONE SAID PEARL<CORAL AND SOME YELLOW SAPPHIRES.SEVERAL KP ASTROLOGERS HAVE RECOMMENDED ONLY EMERALD,WITH ONE SAYING DIAMOND ALSO. IWAS BORN AUGUST 3,1950 AT 5:23 A:M CST IN CHICAGO,ILLINOIS U.S.A. ACCORDING TO KP SYSTEM DOES EMERALD AND DIAMOND GIVE BETTER RESULT AS TRADITIONAL VEDIC ASTROLOGY SAYS CORAL AND PEARL,AND EVERYTHING ELSE IS BAD FOR ME. ALSO DO THE GEMS HAVE TO BE EYE CLEAN AS THEY CAN BE VERY EXPENSIVE? THANK YOU IN ADVANCE TO ALL WHO REPLY,DAN[/quote]
