Cat’s Eye or Lehsuniya is gemstone for Ketu (Ketu is the rest of the body of Rahu). It bestows spiritual tendencies, asceticism, and non attachment to worldly desire1s and ambitions. Ketu is also a half-planet that bestows wisdom, powers of discrimination, and gyana-spiritual knowledge, the knowledge of the self.
Cat’s Eye (Lehsunia stone) is also known as Cymophane or Chrysoberyl Cat’s Eye, this is the name given to the yellow, yellow-green, or grey-green variety of Chrysoberyl, which displays the phenomenon of Chatoyancy (Cat’s Eye). Some fine gemstones are honey brown.
Rahu and Ketu are so attached to each other that they could not be talked about in different sentences. Ketu is almost the another print of Rahu exploring different shades and in different confinements which could be seen in its icon Cat’s Eye Gemstone or lehsunia on land. Similar to the prediction about Rahu, Ketu is also believed to be a shadow image of earth in the study of the universe.

Physical Properties of Cat’s Eye Birthstone
The quality of this gem is judged by the display of chatoyancy effect. A cat’s-eye ( Chatoyancy) is the band of light that runs length wise from one end of the stone to the other. Chatoyancy is caused by a parallel needle or a hollow tube like inclusion inside the gem. When the gem is rotated while light is flashed on the gem, it gives an image of the opening and closing of an eye, thus its name. It is found in a range of colors from yellow to yellowish green, greyish green to brown and brownish yellow.
The natural chrysoberyl rough must be cut in a manner that highlights the cat’s eye effect. This means that the natural chrysoberyl gem should display the opening and closing of the cat’s eye when light is thrown on it and the gem is rotated.
The needles in the stone must be perpendicular to the stone. Thus, a very skillful and experienced lapidarist is required to cut this gem. The gem should be cut in a dome-like oval or round shape, also know as “cabochon cut” (not faceted, just plain polished dome ) and polished to display its chatoyancy.
The commonly used size of the gem in the market is between 0.10ct and 3.00cts. However, gems up to 150 carats in weight are also known to exist. Large gems are rare and are of higher value.
The gem of nature has a milky appearance and transparent gems are almost never found.
