Descrizione

Locality: Namibia

Description: Pietersite, also called "eagle's eye," was discovered in 1962 in Namibia, Africa. Pietersite is a trade name for a dark blue-grey breccia aggregate made up mainly of hawk's eye and tiger's eye. Pietersite is almost always cut into cabochons. This is because, to maximize its chatoyancy, a tall, round cut is required. It is crucial that the cut must be precisely parallel to the length of the pietersite's fibers.

Pietersite's swirling colors resemble a storm, and is known as tempest stone. Traditionally, pietersite has been regarded as a stone of vision.

Chemical Composition: Quartz (SiO₂) with altered riebeckite (crocidolite) fibres, Na₂(Fe²⁺,Mg)₃Fe³⁺₂Si₈O₂₂(OH)₂

Grade: Lapidary Grade
Appearance: Opaque
Inclusions: Some fractures, but overall very stable for pietersite.

Approximate Size of 1 pc: 12cm x 9cm x 7cm
