Diamond
The maker states no particle size. Anything shown is our inference, drawn as such.
Each grade below shows its size in microns, its spread (the published distribution, where a maker or standard gives one; most makers publish none), and where that size lands on the reference scale , a shared yardstick for reading grit numbers across makers.
