I completely agree. I do lots of work with shells (way upscale from the typical $5 surfer girl necklaces) and think that would fall into the same catagory. I've also seen some really interesting beads made of seeds, nuts and bone/horn. That would probably fall into that catagory as well. A great source for those kinds of beads is www.beadsandpieces.com. They also have wood beads--very good prices.
