Gemstone therapy is an important healing arm of Indian horoscope-astrology. The ancient astrological scriptures consistently mention the relationship between color, planets, and gemstones. Just like ‘sound’, color is an ‘energy’ representation in the cosmos. The colors arranged in order of Red, Orange, Yellow, Green, Blue, Indigo and Violet, we see the relation perfectly as we have seven chakras or energy centers along the spine of our body and each is associated with a particular color exactly in order of colors of light passing through a prism.
