Look at http://www.ignorancia.org/tech_page.php?image=6&db=tips
With an adequate pigment, phong or specular highlight and reflection
(constant or variable) values, you can realisticaly simulate most surface.

If you want blurred reflection, you can use this trick:
http://tag.povray.org/povQandT/languageQandT.html#blurredreflection
However, often it's enough to fake a "blurry" look by other means
and the image will still look good (like in the example posted in
the other reply).

This may be what you want. Pay special attention to camera blur settings
and the normal:
default { finish { ambient 0 } }
global_settings
{
assumed_gamma 1
}
camera {
location <0,.5,-5>
look_at 0
blur_samples 500//000//131072
aperture .02
variance 1/384
confidence 0.9
focal_point <-2,0,-1.2>
}
light_source { <0, 2, -100> rgb 1 }
light_source { <-100, 100, -100> rgb 2.5 }
//sky_sphere { pigment { color rgb <0.2, 0.5, 0.9> } }
plane { y, -1 texture {
pigment { checker
rgb <0.02, 0.05, 0.4>*2
rgb <0.02, 0.05, 0.4>*0.5
}
}
interior { ior 1.33 }
}
#declare textured = normal
{
spotted 1 scale .001
}
sphere { 0,10000 pigment { rgb 1 } finish { diffuse 0 ambient 1 } hollow }
sphere { <3,0,4>,1 pigment {color rgb <0.01,0.1,0.7>*1} finish { diffuse
0.7 specular .7 roughness 0.0005 reflection {0.1,1 fresnel }
conserve_energy } interior { ior 1.33 } normal { textured }}
sphere { <-2,0,0>,1 pigment {color rgb <1,0.1,0.05>*1} finish { diffuse
0.7 specular .7 roughness 0.0005 reflection {0.1,1 fresnel }
conserve_energy } interior { ior 1.33 } normal { textured }}
sphere { <1,0,10>,1 pigment {color rgb <0.01,0.5,0.2>*.25} finish {
diffuse 0.7 specular .7 roughness 0.0005 reflection {0.1,1 fresnel }
conserve_energy } interior { ior 1.33 } normal { textured }}
