    Sorry, Your assertions about the hardness of Turquoise are totally
    off base. Turquoise is seldom anywhere near Moh's 7on the hardness
    scale. Since most Turquoise is impregnated with resins you can also
    assume that muchTurquoise is about as hard as the plastic that it
    has absorbed i.e. about a hardness of 3.....
