Here you go !
This is the black marble texture you are looking for.

#declare Black_Marble =
texture{ pigment{marble turbulence 1.0 color_map{
[0.0,0.3 color rgb<0.30,0.30,0.30>color rgb<0.45,0.45,0.45>]
[0.3,0.7 color rgb<0.45,0.45,0.45>color rgb<0.60,0.60,0.60>]
[0.7,0.9 color rgb<0.60,0.60,0.60>color rgb<1.00,1.00,1.00>]
[0.9,1.0 color rgb<1.00,1.00,1.00>color rgb<1.00,1.00,1.00>]
