Pietersite - beautiful, unique minerals discovered in 1962 in Namibia. So far they have been found only in two places on Earth - Namibia in South Africa and Henan Province in China. They belong to the family of quartz minerals.
Minerals are mostly in shades of blue - from very light blue to navy blue. Pietersites originating in China are also found in shades of orange-brown. Pietersite is characterized by its distinctive swirls or streaks of gold or orange, due to the crocidolite inclusions within a microcrystalline silica host. 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. When polished, pietersite exhibits an attractive silky luster.
