It looks like a relatively new item, deliberately "aged". The graduated leaves look dyed, and from the crisp carved edges, not worn from use. They do look like they may have been inspired by the long pointed bone pendants (Sidamo tribe?) used on Ethiopian "waist beads" with red "skunk" eye beads and "feather" beads.
Here are a couple of images borrowed from the net.
