Hello Christian,
These are indeed rather odd beads.
The left specimen is clearly based upon an early 7-layer rosetta bead—and seems to have been overlaid with pieces of Mali millefiori eye beads (that would be about 1,000 years old—so older than the base bead).
The right specimen is more difficult to interpret, since the base is not clearly recognized by comparison. And, also, the chevron beads are not very typical nor easy to ascribe to a time and origin.
I have run your photos through Photoshop, to enlarge slightly and show both views together.
They are both rather curious! Jamey
That these might be "recycled" in Ghana is certainly a possibility. Please review past dialogues on this topic—which is one of my special interests.
What makes your beads interesting is that they cannot be compared to other beads of this genre, that I have documented.
JDA.
