No idea if those stones are more tolerant or not. WHen I get the new one, I'll probably use a tomonagura on it.
Is you surface of your Jnats after lapping like a mirror as I showed it here?

If not you are lapping wrong.
The Diamond is good for to get the surface to a plane (geometry) but it is too coarse to make the surface smooth.

3. Flatten you stone with a diamond stone or a sandpaper, but use another natural stone for final flattening surface need to be as smooth as possible. If you dont have another natural stone to smoothen you stone with use Tomo Nagura or any Nagura you have.
Edit to add: Can you post picture of your stone?
