1st - Noticed this is your very first post - so, Welcome Aboard! You didn't list your state (or country) in your profile. So, you might consider jumping over to Sub-Forums: Select Your Area.... and selecting your state for information (i.e., clubs, hunts, finds, legends, maps, etc.) directly related to your state (or country).
2nd - How did you become the owner of that bracelet?
Did you ever consider that the movie used a piece of tourist trap clap and you have the same type of item? No idea about what you have, but just because something similar was in a movie is really not any indication of a value.
I have the EXACT same bracelet. Got it at a yard sale a few years back. I think we paid $1 for it. It does have a good look to it for a movie, so they probably just used something eye catching but not of much real value.
