Pietersite was discovered by Sid Pieters in 1962 in Namibia, South Western Africa. It is sometimes called Tempest Stone. Pietersite belongs to a branch of the tigers eye family called Riebeckite. Tiger's Eye is what geologists refer to as a pseudomorph, one mineral that changes into another. Tiger's Eye began its life as the mineral crocidolite, a form of asbestos. As quartz replaced the crocidolite it took on the shape of the fibrous mineral and that is what causes the flash of colour, or chatoyancy in gemstones of this family.

This stone is said to stimulate the pineal gland, which produces melatonin–-a hormone that regulates sleep patterns and seasonal functions. Additionally, it is said to enhance your intuition, insight and assist you in reaching specific spiritual goals.
