CHris, I'm having trouble visualizing the bead you are talking about - is it the loose bead on the upper right? I think I have a 12 sided dodecahedron bead from this genre but wanted to know if your bead has 10 or 12 pentagonal sides.

Does the bead with the pyramidal facets on each face have a total of 18 sides ? I'm counting the top & bottom in the total.
