How big is jewelry for Rhino?
I keep hearing that jewelry is only a small part of Rhino. I don’t think so. As for production users I think it’s sizeable. You did not see this pages like these just 4 years ago.
Check out the Job section on Rhino:
http://www2.mcneel.com/rhinojobs/jobs.asp
11 out of 15 are jewelry jobs! These are not stale positions, they expire in 3 months. There is quite an international trend there.
For 3rd party Rhino products there is quite a large section for jewelry:

Also a Indian jewelry designers job board:
