I've missed some of the nomenclature but the ones that I do remember and their diameters are:
Boulder +250MM
Cobble 75-250 mm
Stone 25-60 mm
Pebble 4-64 mm
Gravel 2-75 mm
Sand 0. 062 -2 mm
Like the Arabic "rotl" the terms are user based. A cobble is apparently the size rock that you can pick up and support with one hand while placing it.
There is no opposite to cobble.
Cobble Hill Tunnel was created in 1844.

You have to get the last seachart that huge island on the chart that's the cobble kingdom
The cobble kingdom is actually the isle of ruins. (you need the fourth sea chart) :) :) :)
Success Academy Cobble Hill was created in 2012.
Well, one system says if a grain of sand is bigger than 2mm, it's a pebble, and a pebble bigger than 100 mm is a cobble, and a cobble bigger than 256 mm is a boulder, so you could use "pebble" for "gravel" I reckon.
