Cat’s eye Tourmaline Lehsunia is a gemstone which has a resemblance with Cat’s eye. This Cat’ss Eye Tourmaline gemstone has a striking white ray, passing through the center that gives a resemblance to a cat’s eye. It is the largest encountered gemstone found in natural form. It is a hard, translucent gem ranging in color from a honey yellow or honey brown to yellowish green to an almost emerald green. Cat’s eye tourmaline is composed of mineral of aluminates beryllium. It has a velvety or silk like texture and, when properly cut, displays a brilliant whitish line of light right down the center, appearing almost to be lighted from inside. This stone is also known by many others name as Lehsunia, Chrysoberyl, Vaiduria, Cymophane. It has hexagonal appearance, because of triplet of twin alienated at 120 degree. Black cat’s eye is used to nullify the malefic effect of Ketu.
An important gemological clarification is required here. Several properties in the above description belong to Chrysoberyl Cat’s Eye rather than Cat’s Eye Tourmaline. Tourmaline is a complex borosilicate mineral group that crystallizes in the trigonal system and has Mohs hardness around 7–7.5. Chrysoberyl, on the other hand, is beryllium aluminium oxide, BeAl₂O₄, has hardness 8.5 and an orthorhombic crystal structure that can produce pseudohexagonal twinned crystals.
Lehsunia, Vaidurya/Vaiduria and Cymophane are traditionally associated most strongly with Chrysoberyl Cat’s Eye in the gemstone and astrological trade. Therefore, if this AstroKapoor product is genuinely Cat’s Eye Tourmaline, its laboratory certificate and product description should clearly state Tourmaline rather than Chrysoberyl.
What Is Cat’s Eye Tourmaline?
Cat’s Eye Tourmaline is natural Tourmaline that displays chatoyancy—a narrow reflective band resembling the pupil of a cat’s eye. GIA notes that cat’s-eye Tourmalines occur most commonly in green, blue and pink and that their eye is often broader and softer than the very sharp eye seen in fine Chrysoberyl Cat’s Eye.
The phenomenon is usually produced by numerous parallel tube-like inclusions formed during Tourmaline crystal growth. When the rough material is correctly oriented and polished as a cabochon, light reflects from these aligned inclusions and produces the moving eye.
Cat’s eye Tourmaline is the gemstone of Ketu. It is very excellent in removing malefic effect of Ketu in one’s horoscope. Cat’s eye stone gives auspicious result to the wearer. It has been known, that this stone transform negative thought of a person to a positive one. It promotes tolerance and harmony in one’s life. It stabilizes wisdom and intelligence and removes obstacles of life. It has been found in Brazil, Burma, china and Srilanka, Zimbabwe, Norway.
Associations with Ketu, auspicious results and removal of obstacles belong to Vedic astrology rather than gemological science. Another important distinction is that traditional Ketu recommendations usually refer to Chrysoberyl Cat’s Eye/Lehsunia. A Cat’s Eye Tourmaline should not automatically be assumed to have exactly the same astrological status.
Cat’s Eye Tourmaline Gemological Properties
Indian name – Lehsunia-Sutra Mani
Planet – Ketu
Color – Golden Yellow-Yellow with brown, Green, Lemon, Red, Orange, Pink, Black, Gray, Purple, Voilet, Yellowish Green
Appearance – Tabular transparent crystals
For accurate identification, Cat’s Eye Tourmaline should be described according to Tourmaline properties rather than Chrysoberyl properties.
- Mineral group – Tourmaline
- Mineral class – Complex borosilicate
- Crystal system – Trigonal
- Colors – Green, blue, pink and other colors depending on Tourmaline species
- Mohs hardness – 7 to 7.5
- Specific gravity – Approximately 3.06, with natural variation
- Refractive index – Generally about 1.624–1.644 for gem Tourmaline
- Birefringence – Approximately 0.018–0.040
- Transparency – Transparent to translucent
- Lustre – Vitreous
- Main phenomenon – Chatoyancy

- Cause of eye – Usually parallel growth tubes or aligned inclusions
GIA gives Tourmaline hardness as 7–7.5, refractive index around 1.624–1.644 and specific gravity about 3.06, although values vary because Tourmaline is a group containing several closely related mineral species.
What Causes the Cat’s-Eye Effect?
The white or bright line is not a separate stripe inside the gemstone. It is an optical reflection called chatoyancy. GIA explains that numerous thin growth tubes commonly run parallel to the length of Tourmaline crystals. When they are sufficiently concentrated and the stone is oriented correctly during cutting, they reflect light as a cat’s-eye band.
A properly cut stone should show an eye that moves across the cabochon as either the gemstone or a single direct light source is moved. GIA has even documented rare Brazilian Paraíba Tourmaline showing exceptionally sharp chatoyancy caused by fine parallel growth tubes.
Cat’s Eye Tourmaline vs Chrysoberyl Cat’s Eye
This distinction is particularly important for this product because much of the existing description actually matches Chrysoberyl.
Chrysoberyl Cat’s Eye is BeAl₂O₄, orthorhombic and Mohs 8.5. It is the gemstone most commonly meant when the term “cat’s-eye” is used without specifying another mineral. Fine Chrysoberyl Cat’s Eye can display the famous sharp “milk-and-honey” effect.
Cat’s Eye Tourmaline belongs to the Tourmaline group, is trigonal, has hardness 7–7.5 and usually displays a somewhat softer cat’s-eye effect produced by relatively larger growth tubes.
Therefore, the following existing statements apply to Chrysoberyl rather than Tourmaline: composition as beryllium aluminium oxide, hardness 8.5, Cymophane terminology and pseudohexagonal appearance produced by cyclic twinning.
Cat’s Eye Tourmaline Benefits and Astrology
Gemstone BenefitsCat’s eye/Hessonite brings discipline and self association in one’s life. It can attract sudden wealth, as it is associated with Ketu. It has magical properties to heal negative thoughts and enhance wisdom and intellect. Cat’s eye safe guard its wearer from accidents and evil eye spirits. It saves a person from physical weakness. It brings happiness and serenity in life. Mental comfort is gained by wearing this stone.
An inauspicious Ketu may cause sudden loss and wasteful travels, so it can be prevented by wearing this stone. Cat’s eye is not worn whole life, but it is generally worn during major and sub period of Ketu in person’s life. Each color of Cat’s eye is for different zodiac sign. It is very beneficial for person born under Aries, Taurus and Capricorn.
These descriptions belong to Vedic astrology and metaphysical traditions. Claims about sudden wealth, protection from accidents, evil-eye protection or planetary effects are not scientifically established properties of Tourmaline.
Also, Hessonite should not be grouped with Cat’s Eye Tourmaline. Hessonite is a variety of Grossular Garnet traditionally associated with Rahu in Vedic astrology, while Cat’s Eye is commonly associated with Ketu.
If the stone is being prescribed specifically as a Ketu remedy, the mineral identity should be confirmed first because traditional Lehsunia usually refers to Chrysoberyl Cat’s Eye rather than Tourmaline.
Cat’s Eye Tourmaline Stone Jewelry
Cat’s eye gemstone is used in jewelry-rings, bracelet, and pendant to pacify malefic effect of Ketu. It should be studded in silver. This stone provide stability and attracts wealth. It promotes optimism, generosity and commitment. It increases creativity and confidence to work.
Natural Cat’s Eye Tourmaline can be used for rings, pendants, earrings and bracelets, with cabochon cutting preferred because a curved dome best displays chatoyancy. GIA considers Tourmaline hardness 7–7.5 with fair toughness, making it suitable for jewelry but deserving protection from hard impacts and sudden temperature changes.
Silver-setting recommendations belong to astrological practice rather than gemological requirements. Tourmaline can technically be mounted in silver, gold, platinum or other suitable jewelry metals.
Career and Profession
Writer | Scholar | Poet | Doctor | Judge | Film | Scientist | Film director
Along with the above profession cat’s eye is very beneficial for the person who are spiritual, life counselor, and philosopher. Person of dance, music and acting can also use this stone.
In traditional gemstone practices, Cat’s Eye stones may be associated with concentration, confidence, discipline and intuition, which explains recommendations for writers, professionals, administrators and creative people. Professional success, however, depends on knowledge, experience, skills and practical decision-making rather than gemstone use.
Cat’s Eye Tourmaline Lehsunia for Health
This stone cures leukemia, heart disease, paralysis, hormonal imbalance and leucoderma. This stone is very effective to heal injury after operation.
These statements require a strong medical clarification. There is no reliable scientific evidence that Cat’s Eye Tourmaline treats leukemia, heart disease, paralysis, hormonal disorders, vitiligo/leucoderma or post-operative injuries.
Leukemia, heart disease and paralysis are serious medical conditions requiring qualified professional diagnosis and treatment. A gemstone should never replace medication, surgery, rehabilitation, oncology care or other medically recommended treatment.

For this product specifically, the gemstone report should clearly identify whether the stone is Tourmaline Cat’s Eye or Chrysoberyl Cat’s Eye. This is essential because their composition, hardness, refractive index, density and traditional trade terminology are substantially different.
A useful certificate should include gemstone identity, natural or synthetic origin where determinable, weight, measurements, color, optical phenomenon and detectable treatments.
How to Wear Cat’s Eye Tourmaline Lehsunia Gemstone
Cat’s eye should be cleaned softly with soap and water, and then its ring or pendant studded in silver should be worn in small finger after consulting a Vedic astrologer. An auspicious day is Wednesday, Thursday or Friday for wearing this stone. Its weight shouldn’t be less than 6 carat.
The finger, metal, minimum carat weight and auspicious day described here are astrological recommendations and are not gemological requirements. Their use can vary between Vedic astrology traditions and individual birth-chart interpretations.
From a jewelry-care perspective, GIA recommends warm soapy water as the safest cleaning method for Tourmaline. Ultrasonic and steam cleaners are not recommended because liquid inclusions and thermal shock can cause damage.
Identification of Cat’s Eye Tourmaline Before Buying
Color – Golden yellow, yellow with brown, green with red
Mohs scale hardness – 8.5
Luster – Smooth
Appearance – Bright transparent when polished
Specific gravity – High
The hardness value 8.5 belongs to Chrysoberyl, not Tourmaline. Genuine Cat’s Eye Tourmaline has hardness approximately 7–7.5. Its body color can vary widely, although GIA notes green, blue and pink as especially common colors in chatoyant Tourmaline.
Professional identification can include refractive index, specific gravity, microscopic examination, pleochroism and observation of the characteristic parallel tubes responsible for the cat’s-eye effect. A focused light source is useful for checking whether the chatoyant band moves smoothly across the cabochon.
Six Key Steps in Examining a Cat’s Eye Stone
Whenever possible, examine stones unmounted.
Make sure the gem is clean.
Hold the unmounted stone so that your fingers touch only the girdle.
View the gem under proper lightning.
The original list is titled “Six Key Steps” but contains only four steps. Two useful additional checks are:
- Examine the stone under a single focused light while gently rotating it to observe the movement and sharpness of the eye.
- Check the laboratory certificate to verify whether the gemstone is Tourmaline or Chrysoberyl and whether any treatment has been detected.
A desirable Cat’s Eye Tourmaline should show a visible moving eye, attractive body color, good polish and a well-proportioned cabochon. GIA notes that inclusions create the phenomenon and can therefore add value in cat’s-eye Tourmaline rather than automatically being considered defects.
Vedic Mantra and Pran Pratishtha
Vedic mantra for wearing: “Om ketuaye namah”
Please note that all Gems are already energized (Pran Pratishtha) before sending to our clients by special Pundits and Purohits having in-depth knowledge of Vedas. An auspicious day and Nakshatra is chosen by client Name, Date of birth and Place. A Matt is placed with its face towards East, North or North east while performing Pooja. A snake idol, brass plate, red or grey cloth, horse gram, sandal, kumkum, curd and bowl of sugar is used for pooja and Prasad. Snake idol is placed in front and red or grey cloth is covered on brass plate.
The gemstone is washed with holy Gangajal applied Kum Kum. An incense stick is lighted in front of the gemstone and mantra is enchanted along with marigold flowers in according to the concerned gemstone. After that name of the client, date of birth and place of birth is enchanted by our special pundits and Purohits to energize the gemstone with the concerned person.
This completes the procedure known as “Pran Pratishtha” of Gemstone. This procedure creates a live energy within the Gemstone. The eyes are closed and the mantra is enchanted as per the Gemstones. In Yellow sapphire it’s enchanted 7000 times. Curd is offered as a Prasad and bowl of sugar is donated. After the above procedure is completed the Gemstone is ready to be dispatched to you and since it has been energized you can direct wear it.
Pran Pratishtha, mantra chanting and gemstone energization are religious and spiritual practices rather than gemological treatments. They do not change the mineral’s measurable chemical or physical properties.
The reference to “Yellow Sapphire” and 7,000 mantra repetitions also appears to belong to a different gemstone procedure and should be reviewed before publishing this Cat’s Eye Tourmaline product description.
Buying Certified Cat’s Eye Tourmaline
When buying Certified Cat’s Eye Tourmaline, the first priority should be correct mineral identification. Because Cat’s Eye Tourmaline, Chrysoberyl Cat’s Eye and even fibre-optic glass may all display eye-like effects, the product should not be identified only by appearance.
For Tourmaline, consider body color, sharpness and movement of the chatoyant band, cabochon proportions, polish, cracks, transparency and laboratory certification. A sharper eye can increase desirability, although GIA notes that Cat’s Eye Tourmaline generally has a softer eye than fine Chrysoberyl Cat’s Eye because its tube-like inclusions are larger.
Cat’s Eye Tourmaline Care
Tourmaline ranks around 7–7.5 on the Mohs hardness scale and has fair toughness. It is normally stable to light and most chemicals, but excessive heat or sudden temperature change can cause damage, and heat may alter color in some stones.
Use warm water, mild soap and a soft brush or cloth for cleaning. Avoid ultrasonic and steam cleaners, especially because Tourmaline frequently contains liquid-filled inclusions and growth tubes. Store Cat’s Eye Tourmaline separately from harder stones such as Sapphire and Diamond to reduce scratching.
