Ancient Stone Beads

Ancient beads are hard to nail to any particular time made unless you know exactly where they were found..I've been collecting for a long time and I know these are really old! I can tell by the way the holes through them were drilled and the edges of the holes.. White Banded Agate from the Yuruba Tribe , Africa. They are gently on their way here.. Average size 1.4 inches in length.
