How to Buy a Genuine Cat's Eye (Lehsunia)
Cat's Eye (Lehsunia) is chrysoberyl displaying chatoyance — a single sharp band of light that appears to glide across the stone's dome as it moves — and it's worn in Vedic astrology to address Ketu, the shadow point paired opposite Rahu in the lunar nodes. The first thing a serious buyer needs to understand is that only chrysoberyl cat's eye counts for this purpose; the cheaper quartz version sold under the same name is a completely different mineral.
Genuine chrysoberyl cat's eye reaches the market essentially untreated — there's no routine heat-treatment or enhancement convention here to navigate. The real risk buyers face isn't a hidden treatment, it's material substitution: quartz cat's eye (a much more common and far cheaper mineral that also shows chatoyance), along with tourmaline and apatite cat's-eye material, are frequently sold under the same "cat's eye" name to buyers who don't ask for species confirmation. Only chrysoberyl is recognized as valid for Ketu remedial use, which makes species verification the single most consequential thing to get right when buying this stone.
Cat's eye isn't judged by clarity in the way a transparent gem is — value here is almost entirely about the quality of the eye itself. The sharpness, straightness, and centering of the chatoyant band when the stone is turned under a single point-source light are what separate a fine stone from a mediocre one, and the most prized appearance, sometimes called the "milk and honey" effect, is when the band visibly splits the dome into a milky-white side and a warm honey-colored side. Base body color comes next — a rich honey-yellow to soft greenish-yellow is the classic benchmark tone. Carat weight and overall size matter too, since larger stones that still hold a sharp, centered eye become disproportionately rare. Origin plays a role as well: Sri Lanka (Ceylon) has historically produced the finest, sharpest-eyed material, while Indian sources, including Kerala, supply more of the market's commercial grade.
For astrological use, Lehsunia is traditionally worn in silver or gold on the middle finger, on a Saturday, typically at 4-5 ratti or more — and because Ketu is often considered alongside Rahu in a chart's overall reading, confirming with your own astrologer whether cat's eye is indicated for you, and at what weight, matters more here than general guidance can responsibly provide.

Common Cat's Eye Buying Questions
Is quartz cat's eye acceptable for astrological Ketu use, or does it have to be chrysoberyl?
Only chrysoberyl cat's eye is recognized as valid for astrological Ketu remedial use. Quartz cat's eye is a completely different, far more common and inexpensive mineral, and shouldn't be substituted despite the similar appearance and name.
What should I look for when judging a cat's eye in person?
Turn the stone under a single point-source light and check whether the band is sharp, straight, and centered rather than blurry or off to one side — the classic "milk and honey" split, where one side of the dome looks milky and the other honey-colored, is the most prized look.
