Thanks Loki. By the way, the plane texture is copied from your "sphere on
checkered plane" picture !
My set has ridges too, but it is made of plastic and I thought the stone
sets were smoother. Your remark about the greasy marks sounds great, but I
don't get how to make the variations in the coefficients of specular
roughness (I am still quite a beginner in textures). The texture for the
black stones is simply :

    normal { crackle scale <0.3,0.1,0.3>*0.1 turbulence 0.2 }
    finish { phong 1 phong_size 15 }

Should I use layered finish or something like that ?
