A cut and polished slab of South African tiger's eye, with resin stabiliser run around the edges.
Slabs get stabilised because the fibrous structure that produces the shimmer is also a line of weakness. Cut thin enough to see through the banding and the edges will chip or part along the fibres, so resin is worked in to hold them. It is standard for slab material and it is almost never mentioned on a listing. Nothing has been done to the stone itself.
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: 10.24 x 1.27 x 28 cm
Weight: 635 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.
