  • General : Is serpentine jade?

    I've recently seen serpentine minerals marketed as "jade". As a mineralogist this bugs me, as the term jade to me should be restricted to nephrite (amphibole) and jadeite (pyroxene). I've made the mistake of engaging a few of these dealers, and am told "serpentine is a member of the jade group".

  • Serpentine: The mineral Serpentine information and pictures

    Serpentine is not a single mineral, but rather a group of related minerals. Besides for the main members of Antigorite and Chrysotile, a distinction is not usually made between the individual members except under scientific study and classification.Antigorite usually represents the more solid forms, and Chrysotile usually represents the fibrous forms, especially asbestos.
