Where to find Pietersite
Namibia
The primary and most significant source of Pietersite, particularly the blue and golden varieties. Discovered in 1962 by Sid Pieters in Outjo, Namibia.
China (Henan Province)
A more recent discovery, producing Pietersite with slightly different color variations, often with more reddish and brownish tones, sometimes referred to as 'Chinese Pietersite'.
Collecting tips
- Look for Chatoyancy. The most distinctive feature of Pietersite is its strong, swirling chatoyancy. Rotate the stone under a direct light source to observe the moving bands of light.
- Observe Color Patterns. Pietersite exhibits a chaotic mix of blue, grey, golden, and reddish-brown colors in swirling, brecciated patterns, unlike the more linear bands of Tiger's Eye or Hawk's Eye.
- Examine for Fibrous Structure. Although cryptocrystalline, a close examination (sometimes with magnification) can reveal the underlying fibrous structure of the silicified crocidolite, contributing to its unique appearance.
- Consider Origin. Authentic Pietersite is primarily from Namibia or China. Be wary of mislabeled or imitation materials.
