this might be the surrounding geometry / texture environment / hdri - depending on which one you used.
turn the camera around and and check what the reflection "sees".

there are no other objects in the scene?

just replace the object with a perfect sphere - apply the texture see WHAT EXACTLY is shown in the reflection.
you uploaded a very small and grainy close-up. so we can only guess what the problem is.

ok.
what kernel do you use? if direct lighting - did you try increasing the specular/glossy depth?
if that doesn´t help - can you upload the c4d-file?

Looks to me like you just haven't let it render enough. More passes needed I would say.

problem is possibly related with two specular mixing and big aperture with DL kernel. And your maxsamples is low.
Try different settings, also add hotpixel factor little and try pathtracing
