African Serpentine Chess Set (Malawi)

This is a beautifully carved African Chess set most likely serpentine stone from Malawi. Each piece is hand carved and each one is a work of art by itself, as there are slight differences in even the like pieces.

This is all I have found from my research. I can't find one exactly like it online. The Malawi set is the closest I've found, but still not completely the same. All I know is each piece is extremely heavy for its size and the king and queen are about 4 1/2 inches tall.

If anyone has any more info on this African chess set, please let me know.

Thanks!
