Pietersite

Pietersite is considered a type of tiger's eye, having the same properties as tiger's eye but with different patterns due to its brecciated formation. The fibrous structure in pietersite has been folded, stressed, even fractured and/or broken apart via the Earth's geologic processes. The fibrous materials have then been reformed and naturally recemented together by quartz. While pietersite has the lovely chatoyancy of tiger eye, it is not found in continuously structured bands. Rather it can form in swirls, swathes and fibrous (sometimes linear) segments. Thus the structure of the fibrous streaks in pietersite may appear rather chaotic, and can flow or exist in many directions side-by-side like bold paint strokes. Colors include various blues, golds and reds, that may appear together or alone. Blue is the rarest color, followed by red. The blues range from a baby blue to dark midnight hue. Golds can be light to very deep and rich, sometimes having a reddish hue. All fibrous color variations will have a superb and striking chatoyancy, the bright and subtly changing shimmer of color that moves along the surface of a gemstone as it is viewed from varying angles.
