Scapolite's name is derived from Greek words meaning "rod" or "shaft" and "stone," which describes the shape of its crystals. Originally discovered in 1913 in the Mogok stone tract of upper Burma, scapolite has been found in many locations. However, it is typically found only in small pockets, leading to its status of rarity in the gemstone world. Scapolite is a mineral group of colorless, or translucent pink, orange, yellow, green, blue, violet or purple gemstones.

Cat's-Eye Scapolite

The chatoyancy in cat's-eye scapolites can be caused by hollow tubes or rod-like needles that run parallel to the optic axis. Cat’s-Eye stones can be found Madagascar, Myanmar, Sri Lanka, and Tanzania.

Inclusions
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

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.
