"a tiny ring-like structure about 10 to 20 micrometers in diameter"

On the atomic scale 10 to 20 microns is far from tiny. You're dealing with things this sort of size: which are about 25 microns across and showing much finer structures on the surface. They're easily observable with the light microscope with the fine structure being just about at the limit of resolution.
