(Lansky)Do you get a cleaner polish/finish with a fine diamond stone?

I have the deluxe set, whose highest grit stone is a 1000 ceramic. Though it does get the knife very sharp, the edge finish looks very unclean and foggy. Does the diamond high grit stone get a mirror edge or at least a consistent finish/polish?
 
You have the yellow handle ceramic stone? If so that won’t get you to a mirror polish. You need the sapphire stone with the blue handle.

Sharpen your knife, progressing through the stones, going finer and finer. You definitely need to go fine diamond, yellow ceramic then sapphire to get a nice polish.
 
None of the Lansky diamond hones will come close to producing a polish. As with any diamond hone, they cut much deeper relative to their rated grit. The finest Lansky diamond hone is rated at 600. Compare that to others that almost come to polishing, like DMT's EEF hone, rated at 8000 mesh.

As mentioned, even the 1000-grit white ceramic from Lansky will only produce a hazy finish, still short of mirror-polished.

You can improvise a polishing hone with your existing ceramic hones. Some paper tape affixed to the surface of the ceramic hone and loaded with some polishing compound will work as a hard-backed polishing strop. The ceramic hones are good for this, because their surface is nicely smooth & flat to accept & hold a good bond with some tape.

Hint: Some adhesive-backed mailing labels for envelopes are pretty handy for this, BTW. ;)

I’ll give that a try, thanks for the tip.

Yes.
But that alone will not achieve a clean mirror edge. It’s the last step. Like I said progressing finer and finer, removing all the scratches is the key.

Yeah that's what I've been doing as I have all the stones from 70 grit up to 1000, I will likely try going for the polishing compound solution Obsessed with Edges Obsessed with Edges suggested.
 
lansky also makes a strop that will fit there sharpener that can be loaded with abrasive

holy shit I just got some polishing compound used this method you suggested with the paper tape and ceramic stone and I got a very good result. The finish is much clearer and cleaner, it's finally a mirror finish. And the knife is sharper than it ever was.

Thank you so much!
