Cat's Eye (Lehsunia (लहसुनिया, Vaidurya)) — Gemstone of Ketu (south lunar node): Benefits, How to Wear

Cat's Eye and Ketu (south lunar node)

Cat's Eye, known in Hindi as Lehsunia (लहसुनिया, Vaidurya), is the gemstone of Ketu (south lunar node) in the Navaratna, the nine gems of Vedic astrology. Gemologically it is a chatoyant chrysoberyl showing a moving band of light. Ketu is the headless shadow planet of detachment, past karma, spirituality and moksha. Cat's eye is associated with insight, sudden gains and protection.

Who traditionally wears Cat's Eye?

Astrologers usually suggest Cat's Eye for people in a Ketu period where Ketu is well placed — for intuition, spiritual progress and protection from hidden troubles. The choice depends on the whole birth chart — the ascendant (lagna), the house Ketu (south lunar node) rules and occupies, its strength, and the dasha running — not on the Moon sign alone. A planet that is a functional malefic for your lagna is usually not strengthened with a gemstone.

How to wear Cat's Eye

1. Get the stone tested and certified as natural and untreated (or with the treatment disclosed).
2. Set it in silver or panchdhatu so that the stone touches the skin, as is traditional.
3. On Tuesday, Thursday or Saturday (practice varies), wash the ring in raw milk or Ganga jal, then clean water.
4. Light a lamp and incense, and chant the mantra ॐ स्रां स्रीं स्रौं सः केतवे नमः 108 times, or as your astrologer advises.
5. Wear it on the little or middle finger (practice varies) of the working hand (traditionally the right hand).

Cautions

Like blue sapphire, it is considered quick-acting and is often tried first. Traditionally not combined with ruby, pearl or red coral. Remove the stone if you feel it does not suit you, and consult your astrologer. Weight and quality recommendations (in carats or ratti) vary widely between astrologers.

Substitutes

If the main stone is unaffordable, astrologers often suggest an upratna (substitute) such as tiger's eye, apatite cat's eye, considered milder in effect. Chanting the planet's mantra, charity on its day and fasting are traditional remedies that need no stone at all.

Gemstone recommendations are part of traditional Vedic astrology (jyotish) and practices differ between astrologers and regions. They are not a substitute for medical, financial or legal advice, and no result is guaranteed. Consult an experienced astrologer with your full birth chart before wearing a strong stone, and buy only natural stones with a certificate from a recognised gem-testing laboratory.
