Yes, of course - don't know what I was thinking when I typed "10," I've made many dodecahedron beaded beads.

Bead all by itself is the dodecahedron - two pentagonal ends, 5 pentagons on the upper half, five offset on the lower = 12. The zigzag seam around the circumference was ground.

The goofy bead with the pyramidal faces is the blobby one on the upper right of the strand - my crappy photo doesn't make clear what's going on, but it's not the usual cornerless cube.
