Pietersite can be spelled as petersite.
Pietersite is a variety of chalcedonythat is embedded with fibres ofamphibole minerals (sodium, calcium, magnesium, iron and aluminium). While the fibres cause a chatoyancy effect, it is not found in continuously structured bands or fibres, more in swirls, swathes and fibrous segments. Pietersite colours include various blues, golds and reds, brown and black that may appear together or alone. Blue is the rarest colour, followed by red. The blues range from a baby blue to a dark midnight blue. Golds can be light to very deep and rich, sometimes having a reddish hue.
