To find out what gemstones should be worn by an individual it is necessary to draw up a jyotish birth chart. To do this an accurate birthtime,date and place of birth is required. From this chart it is possible to ascertain which planets in the persons chart need strengthening. This done the gemstone for that planet is selected and a recommended weight chosen.The weight chosen depends on the state of the planet in question.
In the case where the birthtime is not know accurately then a vedic astrologer may be able to perform a rectification; essentially working backwards from known life event dates to a probable birthtime. if this is not possible then it is recommended that a navaratna ring can be worn. As the navaratna ring contains all 9 planetary gemstones it can be worn by anyone no matter what birthtime.
In Vedic Astrology the planets (grahas=those that seize) are nine in number;
sun, moon, mars, mercury, jupiter, venus, saturn, ketu & rahu (the nodes of the moon)
no account is taken of neptune uranus or pluto in this system.
the corresponding gemstones are;
ruby, pearl, emerald, yellow sapphire, diamond, blue sapphire, chrysoberyl cats eye, hessonite garnet
there are also uparatna (substitute gems) They are generally less expensive, they are not as powerful as the primary gems so they may need to be of a higher carat weight.
red spinel/garnet, moonstone, peridot, topaz/yellow beryl, white sapphire, Amethyst/Blue Topaz/Spinel,
