Every setting method has a seat cut to fit the girdle and a small edge of the pavilion. Prongs have cuts which also conform a little edge of the crown, too.
There would typically be beads to hold the stones or just small bits of metal pushed over the edge of the stone with a special graver
The setting method varies with the size of the stones, but the essentials (tiny bits of metal just covering the girdle) seems to be always the same for pave. Their "seats" are either carved into the setting or formed as a lattice to start with. At least, as far as I know.
If prongs are used, that is no longer "pave". Sometimes larger stones are assembled using prongs, but "pave" reffers to the above, as far as I know.
Pave' setting has a seat cut into the metal under the diamond. The diamond is a very tight fit inot the hole where it will sit. Then the beads are brought up by a pointed tool and lots of manual pressure and raised above the stone's girdle. Then they are bent over the edge of the girdle onto the crown. There is a lot more to it after that part is done, but that's the basics.
