If you see someone selling off a mineral under the trade name Chrysotile,Crocidolite, Tremolite, Actinolite, Anthophyllite, Amosite  or quartz with asbestos inclusion please don’t risk your health by buying it. It doesn’t matter what the company may claim, all forms of asbestos are equally harmful and can cause lung cancer. 

Lately I have seen asbestos under this trade name, tigerseye crocidolite is an exception to this as the fibers have been replaced by iron oxides. Tremolite in its fibrous form is literally asbestos so please be aware when buying.
