Natural Chrysoberyl Cat's Eye 6.18 Carat is a remarkable natural gemstone known for its fascinating cat's-eye effect, or chatoyancy. The gemstone displays a distinctive luminous band that appears to move across its surface when viewed under light, creating the characteristic appearance of a cat's eye. Chrysoberyl is a durable natural gemstone with a hardness of approximately 8.5 on the Mohs scale. The cat's-eye phenomenon is produced by fine, parallel inclusions within the stone that reflect light in a concentrated band. The quality of Chrysoberyl Cat's Eye is commonly evaluated by the sharpness, centered position, and movement of this chatoyant band, along with color, transparency, clarity, cut, and overall appearance. Also known as Lahsuniya, Lehsunia, or Cat's Eye, Chrysoberyl Cat's Eye has a special place in traditional Indian astrology. It is traditionally associated with Ketu, and is believed by practitioners of Vedic astrology to support protection, focus, confidence, intuition, and overcoming obstacles. These benefits are based on traditional beliefs and are not scientifically proven or guaranteed.
