We often refer to all small, loose stones as “gravel.”. But actually, there is a fundamental difference between gravel and crushed stone. Gravel is a material of naturally occurring loose stone chunks with rounded edges. You can find it occurring naturally, perhaps in a gravel pit or river. Crushed stone, on the other hand, is manufactured.
