In addition, this opal variety fascinates with shimmering bands of light, which run across the whole stone according to the exposure to light. They remind us of the eyes of a cat, which is just observing you.The wavy light reflection is called „chatoyancy“ (French: chat = cat, oeil = eye). This phenomenon also occurs in other gemstones, especially when they consist of a fibrous mineral structure which runs at a right angle to the base of the stone. The cat’s eye effect shows itself only when the gemstone is cut into cabochons. Cat’s Eye Opals were discovered in 1991 close to Senhor de Pamfir in the province of Bahia. The opal is found in a highly weathered rock in 1 to 3 cm thick veins.Nature rarely grants an opal the phenomenon of the cat’s eye effect. Therefore, the Cat’s Eye Opal has become a popular and rare collectors’s stone.
Cat’s Eye Opal helps to gain a mental picture and to preserve serenity and joy.
