Collection: Cat's eye

Cat's eye stone , also called cat's eye chrysoberyl , is a gemstone that exhibits a unique optical effect called chatoyancy .

🌟 Main Features

• Scientific name: Chrysoberyl (when talking about the real cat's eye stone)

• Hardness (Mohs scale): 8.5 (very strong)

• Color: Usually greenish yellow to golden brown, but can vary

• Luster: Vitreous to silky

• Chatoyancy: A fine luminous line moves across the surface of the stone, like the pupil of a cat's eye — hence its name.

🔍 Origin of the cat's eye effect

This effect is due to the presence of parallel fibers or tubular inclusions in the stone, which reflect light in a particular way. To maximize this effect, the stone is cut into a cabochon (a smooth, curved shape without facets).
