I tested the same on the metallic material and no such artifacts exist.
Ray Epsilon has no affect.
The rings shift around when the metallic parameter is adjusted, in my case around the values 0.9 to 1.0
Can you confirm you are using RC7? I can see this artifact in RC6, and I have already resolved this bug.
Double checking in RC7, I am not actually seeing any of these artifacts anymore.

I have a scene in LW with snow and ice displaced planes that bumps through here and there on an object.. If I displace my ice using LW's displacement I do not get these offending black rings around my specular edges (exactly where they are poking through object and the two surfaces meet).. Switch to Octane displacement and they are there... I'd rather not show this scene, since it is for an ad. Let me know if I need to try and articulate this better.
