Cat’s Eye Opal – Brazilian Magic

Iridescent Green Secret


Who is not fascinated by the mysterious eyes of a cat?

Coming out of a desert in north-eastern Brazil, Cat’s Eye Opals show the magic of yellowish-green to yellowish-brown color tones.

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 phonomenon also occures 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.
