Beragamo,
The VPI ring is Stainless Steel.
As a former machinist I can tell you making a ring like this is difficult and expensive.
You're cutting away about 80% of your material, and it's very tricky to make something that thin stay flat and round.
The VPI price is high, but it's cheaper than buying a CNC lathe to make one yourself :-)
