Pietersite is the trade name for a (usually) dark blue-gray breccia aggregate made up mainly of hawk's eye and tiger's eye. It was discovered by Sid Pieters in 1962 in Namibia, and named in his honor. Pietersite colors include blues, rusty reds, golds and browns.
Pietersite belongs to a branch of the tigers eye family called riebeckite. Tiger's Eye is what geologists refer to as a pseudomorph, one mineral that changes into another. Tiger's Eye began its life as the mineral crocidolite, a form of asbestos. As quartz replaced the crocidolite it took on the shape of the fibrous mineral and that is what causes the chatoyancy in gemstones of this family. Unlike tigers eye, the surface of a Pietersite looks rather chaotic, with streaks and colors in every direction. This is because during formation of the crystal, the materials that compose it were broken apart, swirled every which way, and then were reformed and cemented together by quartz. Stones and crystals that go through that process are referred to as brecciated.
This is my third order from GemSelect. I was 100% satisfied with my first two orders. Their photographs and product descriptions are very accurate and helpful. Selection is great. Shopping is very easy.
This is my second purchase and if it's as great as my first then they will become my gemstone retailer. If my customer's are happy then I am happy then GemSelect will get the extra business. I loved all the items. I do wish that smaller opal facets were available. The Opal facets I received although great were a bit to orange for my customer. I wished they were a bit more opal like. I did have Moonstone's to offer ...
