Cat's-Eye Scapolite Characteristic Physical properties
||The eye in cat's-eye scapolite is distinct and sharp. White, pink or violet material appears fibrous because hollow tubes create the chatoyancy. The cats-eye in reddish brown and brown material is caused by black and orange-red needle like crystals, elongated platelets, or dendritic inclusions. Madagascan material contains needles, hollow channels, and liquid-filled channels. Myanmar material has rod-like cavities or needles. Sri Lankan stones have parallel fibers or channels. Tanzanian material contains iron oxides and filled growth tubes. |
Iridescent Scapolite also known as “Rainbow Scapolite” was first reported in 2013. The iridescence is cause by stringers of Magnetite. Due to the presence of magnetite the stones are magnetic. The stones can be found in India.
