According to Indian astrology, stones are suggested only after verifying one's horoscope. If a planet is weak in the horoscope, wearing the particular stone for it is said to boost the influence of the respective planets in your life bringing with it the related benefits.
For every stone, astrologers recommend a finger on which it is to be worn and an auspicious time to commence wearing it. Astrology doesn't support the wearing of some stones and agrees with the use of others. But this depends entirely on the individual's horoscope. So the wearing of a gemstone should ideally be commenced only after consulting an astrologer. All gems have semiprecious stone.
