The round pieces were probably ornamental pieces worn. The tiny round things were beads.
The little stones that are N S E W look like those "Rose of the Desert" rocks.
The white "arrowhead" shaped things look like Gar Scales. Could have been used for arrow points, but I doubt it.
Not sure on the face in the middle. Could be authentic. Don't know for sure.
The other arrowheads look authentic.
Good find for $10!
