A polished tiger's eye slab, golden brown with the fibre structure visible across the face.
Those fibres are crocidolite, the fibrous form of the mineral riebeckite, and under any other circumstance it would be called blue asbestos. In tiger's eye the fibres are bound into solid quartz rather than sitting loose, which is why a finished, polished piece handles like any other stone and not like a hazard.
The distinction matters only if you take tools to it, which is the one thing not to do.
Mineral: Tiger's eye (a variety name, not an IMA species), quartz (SiO₂) with fibrous riebeckite (crocidolite)
Crystal system: Trigonal
Origin: Northern Cape, South Africa
Hardness: 6.5 to 7 on the Mohs scale; durable, though the polished face dulls if knocked about
Treatment: None to the stone. Resin stabiliser applied around the edges
Dimensions: 8.6 x 1.17 x 28 cm
Weight: 600 g
Note: Do not cut, grind or sand it. The fibres running through tiger's eye are crocidolite, locked into the quartz and inert in a finished slab, but power tools release them as dust.
