Some astrologers prescribe gemstones as a therapeutic measure. I have in the past, but now cease to do so. It is not that I think gemstones are not powerful and wonderful things, they are. Rather I have come in my continuing study of the ancient classics to understand with undeniable clarity that there simply is no reliable correlation of a specific gemstone to a specific planet. Therefore a gem that may work therapeutically for one person often fails to be potent for another person with similar astrological factors, sometimes even being outright detrimental. Gems and crystals are gems and crystals. I encourage you to seek a specialist in that area if you wish to use them.
It is my clear understanding of astrology which makes me conclude that gemology and astrology are not directly correlated. In tens of thousands of ancient verses on the science of astrology, there is simply no definition of the principles astrologers attempt to employ regarding gemstone. That is why I no longer prescribe gemstones as a part of my suggestions for making peace with your planets.
There is no “abracadabra” way to make peace with your destiny, it is a real and practical affair of your inner heart. This is why my favorite techniques involve meditations on ancient prayers, mantras and devotional rituals specifically and clearly recommended by the ancient founders of astrology for making peace with specific planets.

In the West we have something we call “birth stones” – the concept that a particular gemstone is “yours” based on your zodiac sign. The logic behind this is that specific crystalline structures amplify the ketheric resonance of specific planets. So, a ruby, for example, amplifies the astrological energy of the Sun – and therefore people born in the Sun’s zodiac sign, Leo, should wear a ruby.
