Spacers

[absolutme77]

I usually use a thin sterling band as a spacer between my e-ring and WB since I have a e-ring with pave in the undergallery and a half eternity as a WB. I have a number of stacking rings and was thinking of using one as a spacer instead of the sterling band. My only fear is that the rings I'm considering may rub against the prongs of my current rings and eat at them. I included pictures of the rings below - one is a 4-prong full eternity, the other a milgrained channel half eternity. Could either work as a spacer/stacker with my rings or would they cause damage?
My rings on their own:

The full eternity:

The channel set one looks like it will be OK to use as a spacer alternative.

Thanks, glad one of these will work.
