Jewelry design is pretty fantastic. It doesn't seem like something that every silly little girl wants to do, like some of the other corners of the design trade (i'm looking at you, fashion), and it could be a cool area to work in. I took clemson's lapidary arts class, and it was super, despite the fact that it was for 3 hours at 6PM on a Wednesday. Some examples from the Design Innovation Award, 2006 (Several of the pieces look like mall jewelry; the others are delightful) : Georgia Wiseman's ring of rings, from Scotland.

whirlwind ring, by Alexa Blampied:

although I couldn't find a very good picture of this one, it looks like it could've been made in Form-Z, which puts an interesting perspective on scale in those programs. I know engineers use 3d modeling all the time for designing parts, and that's most likely what the programs were created for, but it's interesting seeing something created entirely for aesthetics that could be done. in other news, platinum isn't really the best material for making jewelry out of; it's not that shiny, mostly just rare.
