Cats Eye Stone known as Lahsuniya Ratna in Vedic astrology, is one of the most intriguing and mysterious gemstones. Named for its incredible optical resemblance to the slit-eye of a cat, it is a stone that works quickly, bringing both instant effects and immense long-term benefits to its wearer. A primary "shadow planet" gemstone, Cats Eye is associated with the malefic south node of the moon, **Ketu**. In Vedic astrology, Cats Eye represents **Ketu**—a shadow planet known for being chaotic, reclusive, and spiritual. Ketu is responsible for karmic connections, liberation, and spiritual insight. Because Ketu has a quick-acting and often disruptive energy, Cats Eye is not recommended for general use and should **only be worn after a precise astrological reading**. Psychic Protection: It forms a strong shield against witchcraft, black magic, ghosts, and negative energies, especially for those in mystical or reclusive environments. Karmic Healing Ketu governs spiritual growth. The stone is worn to resolve intense past-life karma and aids in deep meditation. The optical effect that makes the Cats Eye unique is called **chatoyancy**, which originates from a French term.
