Pietersite crystallizes in the form of masses, the structure a result of inclusions in jasper where the inclusions are pseudomorphs after asbestos. 

The color is blue/black and the mineral exhibits a chatoyant quality. It was discovered by Sid Pieters, Windhoek , Namibia , and is truly lovely.

Although crocidelite asbestos is simply a variety of riebeckites occurring in oriented silky fibers as cross-fibre veins, the mane riebeckite is usually applied to the mineral when it is in disoriented rouses. As a rule this material does not enter the re of ornaroentation, but as silica of such material does occur in thus may be suitable for cutting and polishing. That this is so exemplified by an occurrence of silicified reibeckite with limonite which is found in the neighborhood of Outjo in South-West Africa . Attractive variegated golden-brown cabochons of this material have been prepared and marketed by Mr. S. Pieters a mineral dealer of Windhoek , who sells the finished product under the name Pietersite. The density of one such piece was found be about 2.6 and the Mohsi hardness to be similar to that found for tiger-eye. Another alteration product crocidelite reibeckite; consists of a mechanical mixture of silica and hydrated iron and has hardness of 4 on Mohsï scale. This material has been named griqualandite, but it has no place in nur study and as only included in this survey for completeness. A chatoyant fibrous quartz has been obtained on the Cuyuna iron range of Mines in the United States of America . No opportunity to examine this material has presented itself.

Mention must be made of the so-called Hungarian cats-eyes. These yellowish-green chatoyant quartzes containing fibrous amphibloe inclusions are obtained form the database of Holf and other place in the Fichtelgeberge in Ravaria. They do not come from Hungary . Such stones are inferior to the cat-eyes found in India and Ceylon , and probably abey are offen artificial stained different colors.
