Shona Stone Family of 3 African Art Modern Art

A couple of chips in the stone as photographed, heavy, approximately 7 inches tall by 5 1/2 inches long by 2 inches wide. Additional photos show comps. I do not know the artist nor the time period, open to reasonable offers and of course if you have more information on this item, please let me know! Some of the photo comps are of the figure only, not including the stone that surrounds them hence the higher price.
