There are a number of different gravels that you can call "clear" or "clean".

Washed river gravel has a rounded surfaces and can't be compacted. Crushed, washed gravel has angular surfaces that allow compaction, but less than you could achieve with fines. When you get to larger walls with higher loads a washed river or rounded gravel would cause problems. Where as the crusher run washed will hold the load but not show the 95% compaction that you would like to see with a stone that has fines.
