Chrysotile is an asbestiform sub-group within the serpentine group of minerals. There are three known species of chrysotile: clinochrysotile, orthochrysotile and parachrysotile. The chemical formulae for the three are the same: Mg3(Si2O5)(OH)4. Chrysotilevaries in color from gray-white to golden yellow to green. It has a hardness of 2.5 – 3 on the Mohs Hardness Scale which makes it a relatively soft mineral. The three varieties form the fibrous members of the serpentine group and have been extensively mined as asbestos.

Of course, government and scientific agencies disagree, finding that all asbestos fibers can cause asbestosis, lung cancer and mesothelioma.
