Cat's eye or Lehsuniya (for Ketu)
This protects its wearer from hidden enemies, mysterious dangers and diseases. It is normally milky in colour. The gem is very hot in nature. In the event that it does not suit the wearer, the gem sometimes gives immediate signals like uneasiness, restlessness etc.

Cat's Eye is supposed to counter the evil effects of Ketu and diseases caused by Mars. It may prevent unexpected mishaps of life, curing mania, paralysis etc. It protects the wearer from accidents and secret enemies. For businessmen, it is a miraculous result-giving stone, bestowing wealth by secret means like horse racing, gambling, stock exchange market and speculations. It also protects from drowning, intoxication, and Government punishment. It is said to bring fortunes to those who gamble (horse racing, casinos) and should be worn in gold on 2nd finger or 3rd finger of right hand. The weight should be 3, 5 or 7 grams.

Physical properties
Cat's Eye is a gem which displays a band of light at the top which moves when the gem is tilted. The Mineral is chemically known as Chrysoberyl (BeO.Al2O3). The chemical bonding is rhombic. It is generally found in greenish, brownish, yellowish and colourless shades. It has a specific gravity of 3.71 and hardness of 8.5 on the Moh's scale. It is a fairly hard material which wears well as a ring stone, although it is brittle. Occurence
Cat's Eye is found in Sri Lanka, Brazil and India on a very big scale. It is also found in South Africa, Russia, Burma and U.S.A. In India, it has been found in a very big way in Orissa. It is also found in Kerela, Andhra Pradesh, Karnataka, Tamil Nadu and Bihar.

Identification
Being an opaque gem poses certain difficulties in differentiating the natural gem from artificial material. One striking difference which one can tell after some experience of seeing natural Cat's Eye Gems is that the artificial Cat's Eye will be too clear and the Cat's Eye effect will be too marked. But a closer examination under magnification will show signs of a natural gem - like small marks, grains of stone and the small irregularities below the polished surface. The lower part of a Cat's Eye is not polished but only ground, so one can see the roughness of the stone there.

Pearl or Mukta (for Moon)
One who possesses or wears a good pearl enjoys the blessings of Laksmi, the goddess of prosperity. This blessed one will live long and become free of evil, developing vitality and intelligence. He or she will achieve much renown and come to a high position due to the wisdom endowed by the pearl.

Physical properties
The best pearls are moonlike, shining white in colour, with a perfectly round, globular shape. They should be compact, with a high specific gravity, spotless and free from blemishes. The appearance should be lustrous and smooth. Pearls may be white, giving spiritual gifts, rosy, giving intelligence and power, yellow, bringing material prosperity. Black pearls are rare, but are not ideal for development. Coppery or non-lustrous, dirty, cracked, misshapen or otherwise defective pearls should be avoided as they are inauspicious.

Occurence
Pearls are found in Sri Lanka, India, Persian Gulf, Venezuela, Mexico and Australia. Australian pearls are generally considered less desirable. Sri Lankan pearls are considered the best, though pearls from Bahrain are highly prized. In India the best pearls come from Bay of Bengal and fom Tuticorin in South India.

Identification
Pearls grow inside oysters and rarely elsewhere (bamboo, cobra, conch etc). Today cultured pearls are available which may be distinguished from genuine pearls by the bore, which is uniform in the genuine, but thin at the start and wide in the middle in the cultured pearl. Another difference is the structure, which is concentric in the genuine pearl, but parallel in the cultured. Natural pearls are also available. These are created like cultured pearls by the intentional insertion of foreign matter into the oyster, but mother-of-pearl is used rather than glass bead. natural pearls are better than cultured pearls, but both are acceptable if a genuine pearl is unavailable.

Imitation pearls made from fish scales are also sold, but these are not suitable for our purposes. Misshapen or otherwise defective pearls are not suitable either, although very small genuine pearls (too small for jewellery) may be powdered and used for medicinal purposes.

One very important factor, which anyone trying to identify a Gem should note, is that some "faults" are always present in a genuine Gem - their absence and not their presence should be a cause for concern. However, as a rule, any Gem should be shaped in a pleasing manner, lustrous, of pure colour and fine texture. Pearls in particular should not be misshapen.
