Vedic background
Gemstone remedies (ratna) are one of the nine classical upayas alongside mantras, yantras, and charity. The logic: each ratna refracts cosmic rays of a specific wavelength linked to a graha. Authentic Vedic texts caution that a wrong stone can amplify a malefic — which is why traditional practice recommends consulting an astrologer who has read the full chart before wearing one long-term.
