Pietersite is a relatively rare and beautiful mineral that's only mined in Namibia. It can apparently also be found in China but due to flooding the deposit has been closed for many years.
Despite doing a considerable amount of our buying in South Africa which is just across the border, it's still incredibly difficult to find pietersite of this grade for our collection. Most of the material that is available has either been turned into cabochons or is pretty low grade.
This shard of pietersite is quite magnificent and has only been polished on one side. The optical phenomenon of chatoyance can be seen in small sections especially those with darker shades of colour. It would undoubtedly make a superb addition to any collection of rocks and minerals.
