Is it possible to distinguish a diamond grinding wheel from a CBN grinding wheel by sight alone? If so what should I look for there are no markings on the wheel in question. thanks in advance.

Not a very good photo but this is a CBN wheel with two working surfaces on an aluminum hub.

the CBN looks like a rubber similar to a cratex grinding wheel. The Diamond wheel looks like a granular metal surface.

I have also found the need to grind clearance for the
18mm wrench to tighten the compound bolts on a
Nardini I once had.
