You can use plain POV-Ray:
Use micronormals, possibly averaging a few randomly displaced instances. 
You need to use aa to get good results.
Average 100 to 255 large normals randomly displaced.


You can use the experimental Uberpov that support blured reflection 
where you can define a roughness that is to affect the reflection.
In your case, you could use something like:
reflection{0.5 metallic roughness 1}
