Did you try some of the standard stone textures?  Often good to get some 
ideas.

You are usually safe trying a granite texture to start. ( That model 
brings a marble texture to mind also. )

If you want the pigment and the normal to match up you can do something 
like this:

#declare F_Granite =
function {
         pigment {
                 granite
                 scale .20
		turbulence .5
		//this affects the pattern:
                 pigment_map {
                         [ 0 rgb 0 ]
			[ .4 rgb 1 ]
                         [ .6 rgb 0 ]
                         [ 1 rgb 1   ]
                 }
         }
}

#declare T_Statue=
texture{

         pigment {
                 function {
                         F_Granite(x,y,z).gray
                 }
		//this applies the actual colours:
                 pigment_map {
                         [ 0 rgb <.2,.2,.2>  ]
                         [ .5 rgb <.9,.6,.6> ]
                         [ 1 rgb 1 ]
                 }
         }
         finish{ //tweak these
                 diffuse .8
                 specular .5
                 roughness .002
                 ambient 0
                 reflection{0}
         }
         normal {
                 function {
                         F_Granite(x,y,z).gray*.4
                 }
         }
} ;
