This bracelet is formed from a ring of irregular pentagons taken from the center of a Pentagonal Hexacontahedron. So not only do you get a fancy bracelet, you also get to sound all fancy when you tell people what it is. STL files are included for small and large versions. The large should fit over most hands and form a bangle bracelet. The small is for more lady-like hands. For those with larger hands like me, you can cut off a couple of rungs of the small version to make a C-shaped bracelet that is easy to put on and take off, and fits more snugly; this is shown in the orange picture.
