Pietersite is the most sought after pietersite due to its wide rage of colors which includes various shades of blues, golds, and red together or alone. The bluish-grey body color of Pietersite is the most sought and is the rarest color, followed by red. Pietersite is a rare dark blue-grey or reddish brecciated formation (rock made up of fragments embedded in a matrix). It is considered a type of tiger's eye having similar properties but with different patterns due to its formation.

There are only two sources of Pietersite, Africe and China. Pietersite was discovered by Sid Pieters in 1962 in Namibia, Africa. His discovery was published in 1964, and the material was named pietersite. Chinese pietersite is said to have been discovered in 1993, but did not come to market until 1997. Pietersite colors include blues, which range from light or greyish blue to dark midnight hues, red, gold, orange and brown. Chinese pietersite tends to have a brownish-red body color. Namibian pietersite has a bluish body color. Pietersite is also characterized by its chatoyancy which is the result of parallel microscopic needle-like inclusions and appears as multiple reflections of small silky and thread-like streaks of light. With only slight adjustments to its viewing angle, chatoyancy can cause a stone to change from light to dark and back to light again.
