Help identify the Staffordshire Hoard "mystery object"

It's beautiful, but what is it? Archaeologists are asking that question about three gold and silver pieces from the Staffordshire Hoard that fit together. Guesses include a saddle fitting and the decorative terminal to a parchment scroll. (photos)

The gold and garnet cloisonne object is believed to have been originally circular and domed, but it has been damaged. A silver plate was originally riveted inside. Holes were drilled in the object, presumably to allow wire to hold the piece together.

The experts have opened up the discussions to readers around the world. Suggestions may be submitted to Dr. David Symons, curator at BMAG, Research Advisory Panel at the website listed below.
