About Pietersite - History and Introduction
Pietersite is a rare dark-gray or reddish breccia aggregate (rock made up of fragments embedded in a matrix), comprised mostly of hawk's eye and tiger's eye. Pietersite from Namibia was first described in 1962 by Sid Pieters, who named it in his father's honor. The term "pietersite" is now used as a general term to describe brecciated tiger's eye.
Pietersite is characterized by its distinctive swirls or streaks of gold or orange, due to the crocidolite inclusions within a microcrystalline silica host. Crocidolite is the same material responsible for tiger's eye chatoyancy. When polished, the inclusions in pietersite exhibit chaotic chatoyancy whereas in tiger's eye, the inclusions are arranged in parallel lines and give the appearance of a continuous line.
Identifying PietersiteBack to Top
Pietersite can be identified by its distinctive chaotic chatoyancy, caused by brecciated crocidolite inclusions, which appear as golden swirls. Pietersite may have dense or sparse crocidolite inclusions, resulting in a differing appearance. Therefore, it could appear mostly gray-blue, orangey-brown, or an equal mixture of the two.

Pietersite belongs to the large family of quartz gemstones. It is composed of both tiger's eye and hawk's eye. Pietersite is a pseudomorph of quartz, which means that it started its life as another mineral, crocidolite, but over time, quartz replaced the crocidolite fibres. Crocidolite is one of several minerals which belong to the riebeckite family of amphibole silicates.The quartz family includes many gemstones, including many popular gems, as well as some lesser-known quartz varieties too.
The two main branches of quartz include macrocrystalline quartz and cryptocrystalline quartz. Macrocrystalline quartz includes transparent to translucent gemstones, such as amethyst, ametrine, rock crystal, blue quartz, citrine, prasiolite (green amethyst), quartz cat's eye, smoky quartz and rose quartz. Hawk's eye, tiger's eye and pietersite are rare examples of opaque macrocrystalline, as most other quartz gem types have excellent transparency. Cryptocrystalline quartz includes a wide variety of opaque to translucent quartz gemstones, including agate, onyx, chrysoprase, bloodstone, jasper and carnelian.

Pietersite Gemstone Jewelry Care and CleaningBack to Top
Pietersite is quite a tough substance that is suitable for everyday wear, but in order to maintain its luster and color, it should be cared for properly. To clean your pietersite, simply use soapy water and a soft cloth. Be sure to rinse well to remove soapy residue. As with most gemstones, ultrasonic cleaners and steamers are not recommended. Always remove any jewelry or gemstones before exercising, cleaning or engaging in harsh physical activities such as sports. Store pietersite away from other gemstones to avoid scratches. It is best to wrap gemstones in soft cloth or place them inside a fabric-lined jewelry box.
