2021 series! "Pocket stones" 40-45 mm Tigereye from South Africa.

Tiger eye is a quartz variety. The color of the stone is tan to brown, streaky and opaque. Locations include Africa, India, Mexico, California and Australia. Tiger's eye is caused by the black-blue asbestos silica-tion process called crocidolite. This creates solid inclusions of hair-like crystals in the quartz. The oxidation of the original crocidolite fibers creates the gold shiny limonite fibers of the stone. Tiger's eye is so named because the stone has a light reflection that is reminiscent of a tiger's eye. This slit-shaped light effect is called chatoyeren or "cat's eye effect". When the stone is cabochon (convex) cut, the beautiful cat's eye effect is best visible. The color of the stone gives it its name: the red type is called Cat's Eye, the blue Falcon's Eye and the yellow Tiger's Eye (golden yellow, golden brown).
