Gemstones have been worn for their power since ancient times, and in India gem therapy is regarded as a natural science practised for thousands of years. Far from mere superstition, it rests on the principles of colour and light energy. Here is the science behind wearing gemstones and how gem therapy is believed to work.
The Scientific Basis: Colour and Light
Gem therapy works through colour therapy. Each gemstone transmits one of the seven primary colours — red, orange, yellow, green, blue, indigo and violet — and each colour carries a different wavelength of light that interacts with the human body. Even modern science increasingly explores how light and colour affect health, echoing the ancient logic that the right colour, absorbed through a gemstone, can rebalance the body’s energy.
What Each Colour Does
Yellow stimulates wisdom and ambition and supports digestion, skin and memory. Green brings the freshness of nature, promoting peace and happiness. Blue connects to spiritual dimensions and strengthens immunity. Orange aids renewal and lifts low moods and boredom. Violet eases depression and fosters affection. Indigo calms the nervous system and is linked to relief from migraines and eye strain, and white, blending all colours, brings peace and calm for stress relief.
How This Links to Astrology
In Vedic astrology, each planet is associated with a colour and a gemstone, so wearing the right stone channels the beneficial colour-energy of a strong planet or strengthens a weak one — the basis of the nine gemstones and their planets and the seven chakras and their stones. This is why the correct stone must match your chart.
Getting the Right Gemstone
When recommended correctly by an expert, gemstone therapy is believed to gently support conditions from stress to body pain — but it works best as a complement to, not a replacement for, medical care. Because the wrong stone can do more harm than good, always get a proper Vedic gemstone recommendation before wearing one.
