Guan-Di Amulet (My Name Is Bruce) - Found Item?

[Howlrunner]

Watched My Name Is Bruce for the first time last night and found it a lot of fun. Mr Campbell doing what he does best!

I was wondering, is the magical amulet that holds Guan-Di imprisoned custom sculpted for the film, or was it found? The low budget may mean it was a found item, but then Guan Di's costume (with what looks like custom sculpted metalwork) was made for the film.

Best pics I could take:

Nothing about this amulet at all on any of the documentaries on the 2 disc set.
