I agree this is the most exciting use of CAD that I've seen and
thanks for bringing it to our attention. I don't make convention
jewelry so three stones rings and such don't do it for me. This is
not a criticism of those who do make those things.
I spent some time looking at Bathsheba's site in amazement at the
things she's producing and the technology that allows her to make
them. The thing that struck me is the perfection of the mathematical
models of the sculpture.
Wm Morris once wrote an essay about the 'touch of the hand' in
making things. The essence of his essay was as I remember it was that
no matter how hard one tries to make a thing perfect, one can't
because of 'the touch of the hand'. The evidence remains that the
object was hand made. Perhaps if it's done just so; there's even a
little bit of the maker's soul in the object. These mathematical
models are so perfect that they look a bit alien in their perfection.
If the work you do doesn't change you; you're not doing it right.
