Physical properties
Hardness: 6.5-7 (Mohs scale), Color: Swirls of blue, gold, and red, Luster: Silky/Chatoyant, Crystal Structure: Trigonal (as Quartz), Cleavage: None/Conchoidal fracture, Specific Gravity: 2.64-2.71
Formation & geological history
Formed through the brecciation of tiger's eye and hawk's eye, where fragments were later re-cemented by silica. Primarily found in Namibia and China.
Uses & applications
Mostly used in fine jewelry (cabochons), as metaphysical stones, and as high-end collector specimens due to its limited availability.
Geological facts
Known as the 'Tempest Stone' because its swirling patterns often resemble a storm. It was discovered by Sid Pieters in Namibia in 1962.
Field identification & locations
Identify by its unique 'chatoyant' shimmer that appears to move as the stone is tilted. It is distinctly brecciated (fragmented and re-joined) compared to the linear bands of standard Tiger's Eye.
