Just something to ponder on... If you take 2 similar settings, one with say a 1mm stone & another with a 10mm stone.

If you were to magnify the smaller to the same size as the bigger, you should find they look about the same.
In other words, the amount of metal holding a stone remains constant relative to their size.

The thickness, bead, claw, bezel remain fairly consistent relative to the size also.

There are always instances of exceptions, but I`d say overall it`s a safe way of figuring out how you should be looking at things.
