Detailed Product Description
Natural Quartz Cat's Eye (Lahsuniya) – 5.61 Carat (6.16 Ratti) Cabochon
This Natural Quartz Cat's Eye (Lahsuniya Ratna) weighs exactly 5.61 Carats (6.16 Ratti) with calibrated dimensions of 13 x 9 x 7 mm. Expertly fashioned into a smooth, polished Cabochon, this Earth-mined gemstone displays a characteristic silky chatoyant band that glides across its surface under directed light.
Mineralogical Identity & Physical Constants: Cat's Eye Quartz is the precious optical variety of Natural Quartz (silicon dioxide, SiO2) exhibiting the diagnostic phenomenon of chatoyancy (the "cat's eye" optical slit). This effect is produced by light reflection across fine, dense, parallel microscopic fibrous inclusions (such as rutile or amphibole needles) aligned perpendicular to the cabochon base. Ranking at Mohs hardness 7.0, it exhibits a refractive index of 1.544 to 1.553 (birefringence 0.009, uniaxial positive), a specific gravity of 2.65 to 2.66, and a diagnostic trigonal crystal system.
Geographical Origin & Lapidary Profile: Mined from authentic crystalline pegmatite belts of India (notably Odisha, Andhra Pradesh, and Rajasthan), this gemstone is 100% natural, unheated, and untreated. It is free from thermal treatment, chemical dyes, and synthetic resin stabilization. It has been shaped en cabochon by skilled lapidaries to achieve maximum definition of the central chatoyant ray.
Cultural Legacy & Traditional Wearing: Known in Sanskrit as Vaidurya (वैडूर्य) and universally in Indian tradition as Lahsuniya (लहसुनिया) or Lehsunia, cat's eye is historically linked in Vedic astrology with the descending lunar node (Ketu / केतु). In classical traditions, it is customarily mounted in Panchdhatu or Sterling Silver (925 Silver) for rings or pendants worn on the middle finger (Madhyama) or little finger (Kanisthika) of the working hand.

Care Instructions
- Clean gently with lukewarm water, a mild dish soap solution, and a soft microfiber cloth, then pat completely dry.
- With a Mohs hardness of 7.0, quartz cat's eye offers good durability for regular jewelry wear, but should still be shielded from violent impacts and hard abrasive surfaces.
- Avoid ultrasonic and steam cleaning: Internal parallel fibrous structures are best preserved through gentle manual cleaning.
- Store separately in a padded jewel pouch to prevent scratches from harder gemstones like corundum (sapphires/rubies) or diamonds.
